Please visit our website for more information on this topic.

What Is Injection Molding

An injection molding process involves the injection of molten material into a steel injection mold and then allowing the material to cool, resulting in a solid shape and then ejected by an ejection system . It is possible to manufacture a wide range of objects via injection molding, including automobile parts, toys, and medical devices.

Material, usually metal or plastic, is melted inside the barrel at the beginning of the process. A high pressure injection is then used to inject the molten material into the mold via sprue,ruuner and gate. It is opened and ejected from the mold when the matter has cooled and solidified enough. The process of injection molding can be used to produce mass quantities of objects quickly and at a reasonable cost.

An overview of injection molding history

A history of injection molding can be traced back to the s. Alexander Parkes invented a method for molding cellulose into objects in , marking the beginning of injection molding. The first plastic injection molding machine was patented by John Wesley Hyatt in .

As a result of this machine, plastic objects could be mass produced in large quantities in a short time. With the advent of mass-production of plastic products in the early s, injection molding became increasingly popular. Medical devices, automotive parts, and electronics are among the types of products injection molded today.

Reliable China injection molding Suppliers: Why You Should Choose Them

It is important to select a reliable China injection molding supplier when you are facing so many suppliers. The importance of this can be attributed to a number of factors- the financial position of the China injection molding supplier, their experience in the industry and their reputation. In , the demand for injection molding products in China reached 25.77 million tons- an increase of 1.470 million tons from , an increase of 6.0% year-on-year, and the demand for injection molding products in China is expected to reach 26.91 million tons in

Some quality factors to consider when selecting a reliable China injection molding supplier- whether or not they have a factory, what type of quality assurance system they require and how many employees they have.

You may not be able to obtain high quality injection molding parts if your supplier is not reliable and your customers may become unhappy as a result and sales may be lost. With a reliable and flexible China injection molding supplier, you can win over customers who may be apprehensive about purchasing injection molding parts.

It is also possible that an unreliable injection molding supplier will not be able to deliver your products on time, which could result in sales being lost.The time it takes for the recipient to receive the order.You should ask the plastics supplier about their average time for delivery.

The third disadvantage is that you will have difficulty obtaining after service assistance from an unreliable supplier if there is a problem with your order.

There are a lot of risks involved in purchasing goods without any protection. You might not receive the item you ordered and the supplier might refuse to give you a refund. If this happens, then it will be hard to find someone who can help you get out of the situation.

Last but not least, working with a reliable injection molding supplier is generally more convenient- you will typically receive better customer service from them. They’ll take into consideration any requests you may have and give the same weight as any other business. they might even be able to secure you a refund in certain circumstances if their error caused you a problem.

Finding a potential injection molding supplier in China: How To Do It

Research is crucial when looking for mold manufacturers in China . It is possible to research potential plastic molding suppliers in a few different ways, and each has its own advantages and disadvantages.

Searching online – alibaba.com, made-in-china.com and globalsource.com – for potential suppliers is one method of researching potential suppliers. By doing so, you will gain a better understanding of what products or services a supplier offers, as well as their pricing. Nevertheless, keep in mind that not all information found on the internet is reliable, and it is important to do your research before making any decisions. Also you could find many suppliers via google.com and bing.com. In addition, you can also search for Chinese suppliers on social media platforms- facebook.com,linkedin.com, Instagram.com,pinterest… -many suppliers have their own social media accounts, and you can search for relevant keywords on these platforms to find suppliers of interest and make contact.

It is also advisable to speak with other businesses who have used potential suppliers in the past to conduct further research. The purpose of this is to provide first-hand information about the quality of the company’s products or services, as well as the level of customer service they provide. It is an absolutley useful way to avoid fraud suppliers

You could also attend a trade show– Aisamold and Chinaplas . There are many trade shows that feature Chinese injection molding suppliers. This is a great way to meet potential suppliers and learn about their products face to face.

Another method you can use to find a China plastic injection supplier is to contact a sourcing agent. Sourcing agents are companies that help businesses find suppliers in China. They have experience working with Chinese injection molding suppliers and can help you find the right supplier for your needs.

Get quotations from multiple Chin injection molding suppliers

If you’re looking for an injection molding supplier in China, it can be difficult to find the best one: with so many different companies competing for your business, it can be hard to find the best price and quality.

To make sure you’re getting the best deal available, it’s important to take a few minutes to read through the supplier’s website and compare prices between them.This is where Blueprints can help.

Asking Your potential China injection molding suppliers the right questions

If you have any questions or concerns about the product or service being provided, it is important to speak with your China injection molding supplier , especially if the supplier is based in China.

By doing so, you can get answers to any of your questions and ensure that your purchase is in good condition. It is also important to be aware of any potential problems that may arise. If you have any questions about the injection molded product or service, it is best to reach out to the supplier.

In order to enter into an agreement with a Chinese supplier, the following 4 questions should be asked:

1. How long has your company been in plastics business? As a result, you will be able to gain a better understanding of the company’s experience and how long it has been in injection molding and tooling business. The company’s website should provide a list of services or products they offer, as well as some examples of customers who have purchased these items.You should also pay attention to the lists: whether they focus on international or domestic operations, how long their business has been in operation, the size of their workforce and where they are located.
2. How would you describe your main plastic products and services? In order to determine whether the company is a good fit for your needs, you should know what it specializes in, and how it operates .You should also be aware of how long the company has been in business, as this can indicate whether it is trustworthy or not.
3. Are there any references you can provide? By speaking with references, you can gain an initial understanding of both the quality of the injection molded products and services offered by the company. In addition, you can gain an understanding of their level of customer service. and their ability to meet deadlines.
4. What is the minimum order quantity (MOQ) for your products?Minimum Order Quantity, or MOQ, is a set number of injection molded units that must be ordered for a certain product to be made in one batch. This often prevents companies from taking on small orders and can lead to high costs per unit. Despite this, there are some benefits of MOQs, including the added security of having enough inventory to last an extended period of time.

A supplier contract should include the following features

It is important to look for certain key elements when entering into a supplier contract to ensure that your company is protected. You should be aware of the following:

1. Contract scope – The supplier’s scope of work should be clearly defined in the contract. As a result, there will be no misunderstandings in the future. There are a number of different types of contracts. The contract should have the following elements: the name of the parties, the time period for which it will cover, the subject matter of the work to be performed, and-its scope.
2. Pricing – Ensure that the contract clearly states the pricing to avoid surprises down the road. Price term (Incoterms) includes: FOB (Free on Board), CIF (Cost, Insurance, and Freight), CFR (Cost and Freight), CPT (Carriage Paid To), DDP (Delivered Duty Paid).
3. Terms of payment – Before signing any contract, make sure you understand the terms of payment. Getting stuck with unexpected costs is not something you want to happen.Be sure that you know what your supplier is asking for when it comes to payment. You should be prepared to pay upfront or in installments. Normally for injection mold: 30% down payment, 30% after cutting and 40% after samples approval.
4. Delivery schedule – Make sure that you and the injection molding supplier are on the same page when it comes to delivery schedules-normally for tooling,6-8 weeks. By doing this, you will be able to avoid any delays in receiving your goods or services. As mentioned earlier, it is essential to understand the risks involved with injection molding and make sure that you are prepared. If you want to lower your risk of experiencing a delay in production or a poor quality product, then it is important for you and the company that will be handling your injection into have an agreement in place.

It is important to be aware of the different cultural customs and norms when interacting with people from other cultures. It is also important to be patient when learning about the customs of others. When communicating with people from other cultures, it is important to use proper grammar, vocabulary, and idioms. If you are able to show respect for the cultural values of others, you will be able to build a strong relationship that can help facilitate better communication.

With these tips, you can build a good working relationship with your supplier that benefits both of you.

Visiting the China Supplier’s Factory

Before placing an order to a new China injection molding supplier, it’s always a good idea to visit their factory. This will give you the opportunity to see the injection molding manufacturing process and meet the people who will be making your products.

It’s also a chance to make sure that the factory is up to your standards in terms of cleanliness, safety, and working conditions.

When you visit a China plastic injection molding supplier’s factory, there are a few things you should keep in mind.

When planning your visit to a factory, it is important to consider when the business is open-most. Many Chinese injection molding suppliers also work on Saturdays, which is one of the secrets of their ability to make money. During business hours, you will be able to see the factory in action and get a better understanding of how the products are made. Make sure to schedule your visit for during these times so that you can maximize your experience.

• If you’re not happy with the price or delivery time offered by a supplier, don’t be afraid to counter-offer. Many Chinese suppliers already leave room for counter-offer on their first offer.
• Make sure to be clear about what you are looking for, and be prepared to walk away from a deal if you don’t think it’s fair.
• Be persistent, but don’t overstep your boundaries; remember that your China injection molding supplier is also trying to make a profit. Do a fair deal.

When visiting a supplier’s factory in China, be sure to schedule plenty of time to tour the facility and meet with key personnel. Be prepared for a language barrier, as most workers will not speak English.

While on the tour,

• Pay close attention to the cleanliness of the injection molding factory and whether or not safety precautions are being followed.
• Pay attention to the availability of a relaxed working environment.
• Ask questions about the molded production process and get a feel for how organized and efficient the operation is.
• Finally, be sure to inspect the plastic products that are being produced to ensure they meet your quality standards.

By taking these steps, you can get a good sense of whether or not a particular supplier is right for your company.

Conclusion: The Importance of Choosing a Reliable China Injection Molding Supplier

As the world increasingly turns to China for injection molding manufacturing needs, it is more important than ever to choose a reliable supplier. This is especially true when it comes to injection molding, as the process is complex and requires precision. There are many factors to consider when choosing a supplier, such as cost, quality, and delivery time.

To some people, DFM (design for Manufacturability) might seem a little overkill or an unnecessary step in the already lengthy process of developing a new product. However, it is one that we at Sofeast take seriously and is a step that pays off time and time again resulting in saving time, money, and headaches down the line. Here’s why tooling DFM is crucial for successful injection molding.

Let’s look at a scenario where you are thinking about skipping tooling DFM: you think you have a great design, and you move straight into mold tool production, however, during mold tool production, unexpected challenges arise. The design needs modifications, leading to delays, rework costs, and a dent in your budget. Tooling DFM would have helped you avoid this nightmare scenario.

By proactively identifying potential issues early on, Tooling DFM saves you from costly fixes later. It analyzes your design through the lens of manufacturability, highlighting areas that could lead to expensive mold modifications or production delays. Addressing these concerns early in the design phase minimizes rework and keeps your project on track, both financially and temporally.

But DFM doesn’t stop there. It also helps you choose the right material for your needs, minimizing waste and reducing material costs. Additionally, a DFM-optimized design translates to smoother production with less downtime and potential machine adjustments, further saving you operational costs. In essence, DFM helps you get the most out of your investment, ensuring every penny counts towards a successful outcome.

DFM also plays a key role in ensuring your injection molded parts meet the highest quality standards. It considers critical factors like wall thickness, draft angles, and gating, minimizing the risk of shrinkage, warpage, and other defects that can impact part quality and functionality.

In the image below you can see our own internal feedback during DFM on a product about the size of the gate and the requirement to add some material on the inside of the rim which shows the level of detail the team goes into during a DFM review to ensure that we have the absolute minimum gate mark on the surface of the product.

We get asked about plastic injection molding cost on every project we manage and it is not always that easy to answer. Let’s break it down into two parts, first, the cost of the mold tools and second, the cost of the injection molded parts.

A. Injection mold tooling cost

When it comes to injection molding, the tooling itself is the most expensive part, but what factors contribute to all the cost?

The complexity, size, and material of the mold heavily influence its cost. Here’s a closer look at each factor:

• Complexity: Simple, single-cavity molds with basic geometries are naturally cheaper than intricate, multi-cavity molds with complex features like undercuts or tight tolerances. The more intricate the design, the more machining and finishing work is required, driving up the cost. Simple, single-cavity molds for small parts might cost around $1,000-$5,000, while complex, multi-cavity molds for high-volume production can soar to $25,000-$80,000 or even more.
• Size: Larger molds require more material and machining time, resulting in a higher price.
• Material: Steel is the most common mold material due to its durability and heat resistance. However, it’s also the most expensive. Aluminum offers a cost-effective alternative for simpler molds or low-volume production but with potential limitations in durability and heat tolerance. These days, aluminum tools are not very common in China as most toolmakers prefer to go directly to steel.

Where would the mold tooling usually be fabricated?

Most mold tooling is fabricated in China; mostly around Dongguan and Ningbo, where there is a very dense network of toolmakers and prices are quite competitive. Here’s our advice for you when requesting quotes from mold tooling shops in China.

B. Plastic injection molding cost for parts

Several factors will determine the plastic injection molding cost for your parts with the material selection having a significant part in this equation. We have already touched on some of the plastics commonly used, however, it is not the cost of the material that should influence the selection, it has to be the required properties like strength, heat or chemical resistance, etc.

Another factor that will impact the cost is volume. High-volume production benefits from economies of scale, bringing the cost per part down especially if multiple parts can be molded with a single shot (multi-cavity tooling). Conversely, low-volume projects might have a higher per-unit cost due to mold setup and processing costs.

We’ve written more about the costs of tooling and purchasing process in these blog posts:

• How to avoid paying in full for your tooling
• Buy China Tooling For Plastic Production Abroad? (Benefits & Risks)
  
• Should Tooling Fabrication and Plastic Injection Molding Be Done Together?

As with the question about costs, the answer to how long it takes to make a mold tool is not a straightforward one as no two projects are the same.

Mold complexity is probably the single most influencing factor to the time it will take to fabricate your mold tooling. Single-cavity molds with basic geometries are quicker to create, often taking 2-4 weeks. But intricate designs with multiple cavities, tight tolerances, or complex features like undercuts can push the lead time to 6-8 weeks or even longer. The more intricate the design, the more steps and time required.

The second part of this complexity equation is the mold size. The more cavities involved, the larger the mold itself, the larger the mold, the more machining is involved which increases the time.

Another factor to take into consideration is the mold maker’s schedule. With a busy workshop, your mold may have to wait its turn which adds to the overall lead time. On top of the mold maker’s lead times, you have the supply chain to consider where material shortages or delays in components like cooling systems can add unexpected waiting periods.

Key factors to remember when planning the build of your mold tool are:

• Estimates are your friends: Experienced mold makers can provide an initial estimate based on your design and requirements. Keep in mind, that this might change depending on unforeseen circumstances.
• Communication is key: Stay in touch with your mold maker throughout the process. Understanding potential delays and adjustments helps manage expectations and adapt your timeline accordingly.
• Planning is crucial: Factoring in the mold lead time when planning your overall project timeline is essential. Rushing the mold creation often compromises quality and can lead to costly rework later.

An example of the difference in mold tool fabrication lead times between China and India, and why they’re not the same.

China is still the fastest place to have mold tooling fabricated. The same mold might get made in 3 weeks in China (not including DFM, mold design, first trial, etc.), and 7 weeks in India, simply because Chinese toolmakers have automated the processes much more than in India where a lot of the finishing is done by hand (which is a more labor-intensive process).

Prototype plastic injection molding is a must for prototyping your design before mass production for many businesses, as it is crucial for identifying flaws, refining functionality, and ensuring a smooth transition into the tooling phase. While 3D printing has emerged as a popular prototyping tool, various injection molding-specific methods offer distinct advantages and cater to diverse needs. Here we will look at the different prototype tooling methods, exploring their materials, lead times, limitations, and what they can produce:

Rapid Injection Molding (RIM):

This method utilizes simplified, single-cavity molds often crafted from aluminum or epoxy resin. These molds are quicker and cheaper to create compared to their production counterparts, offering faster lead times and lower upfront costs.

• Materials: Aluminum, epoxy, nickel-plated steel (for higher durability)
• Lead Time: 2-4 weeks for simple designs, longer for complex geometries
• Limitations: Limited part size and complexity, lower durability and repeatability compared to production molds, potential dimensional deviation from the final part
• Applications: Functional testing, design validation, low-volume production runs

Prototype Insert Molding (PIM):

PIM leverages inserts made from materials like aluminum or beryllium copper, integrated into a standard production mold base. This offers faster lead times than full production molds while delivering closer quality to the final product.

• Materials: Aluminum, beryllium copper (for higher heat resistance), steel (for complex geometries)
• Lead Time: 4-6 weeks for simple designs, longer for intricate features
• Limitations: Can be more expensive than RIM, limited to mold base configurations, might still not be a replica of the final production part
• Applications: Functional testing, design verification, pilot production runs, pre-production validation

3D Printing for Injection Molding Patterns:

The 3D printing rapid prototype approach utilizes 3D-printed patterns to create sand molds for casting metal molds. It offers a relatively fast and affordable way to produce prototype molds, particularly for simpler geometries.

• Materials: 3D printing materials like ABS, SLA resins, SLS nylon (for better heat resistance)
• Lead Time: 1-2 weeks for simple designs, longer for complex geometries
• Limitations: Limited material options, lower mechanical strength, and heat resistance compared to metal molds, not ideal for complex geometries or high-precision parts
• Applications: Initial design verification, early testing, low-volume prototypes with simple shapes

In many cases, going straight from 3D printing to hard steel tooling makes sense when one considers the overall lead time of the project. One common exception is product designs that rely on technical assumptions that can only be validated by getting parts in the right polymer coming out of a mold.

Aluminum seldom makes sense if a mold is fabricated in China (which we cover later). Steel is the most common injection mold material, but choosing the right injection mold steel material is similar to selecting the foundation for a building: it dictates the mold’s durability, performance, and ultimately, the quality of your parts. As engineers, we understand the critical nature of this decision.

Let’s delve into the three most common types of hard steel and pre-hardened steel utilized in injection molding:

Hard Steels:

1. / / H13: This trio offers a workhorse option. After hardening, they achieve a Rockwell C hardness of 49-53 HRC, making them suitable for ordinary hardening molds. Their versatility allows for applications across various projects.

ESR: This steel takes the performance of the previous group a notch higher. It boasts the same hardness range (49-53 HRC) after hardening but excels in applications demanding both durability and a highly polished finish.

S136 / S136SUP / : Don’t be fooled by the “steel steel” reference – these are actually high-performance stainless steels. Their strength lies in corrosion resistance, making them ideal for molds processing materials like POM and PVC, which can be corrosive to standard steels. Additionally, they hold their own when it comes to achieving a polished finish.

Lifespan: Mold tooling made from hard steels like 1.#, #, and # will usually last for around 300k-500K shots, but can reach 1 Million if the mold structure is simple.

Pre-Hardened Steels:

S50C / S55C: These steels offer a cost-effective option for mold bases, providing adequate strength and machinability. However, their lower hardness limits their suitability for high-wear applications.

718 / 718H: Renowned for their toughness and ability to achieve a good surface finish with standard polishing techniques, 718 and 718H are popular choices for mold cavities and inserts. Their well-rounded properties make them a versatile option for various applications.

738 / 738H: Offering superior rigidity compared to 718 grades, 738 and 738H excel in core and insert applications. While their polishing capabilities are considered “ordinary,” their rigidity often outweighs this limitation for specific applications.

A Note on P20: It’s important to clarify the perception of P20 steel in China. While technically encompassing a series that might include materials like 718 or 738, the term “P20” in China often refers to a lower-grade steel with potentially less desirable properties compared to the 718/738 series.

NAK80 / XPM: The champion of pre-hardened steels, NAK80 boasts a hardness of 37-43 HRC. This, coupled with its excellent polishing capabilities, makes it the go-to choice for molds requiring high-precision parts from materials like PC, PA+GF, and PC+GF.

Remember, this is just a starting point. Selecting the optimal steel grade requires careful consideration of factors like part complexity, plastic-type, production volume, and budget. Consulting with experienced mold makers and material suppliers is crucial to ensure you make the best choice for your specific project.

Lifespan: For pre-hardened materials the mold life is usually 100K-300K shots.
In particular:

• 278#; 718#; p20#: 100k-200K;
• NAK80; XPM: 200-300K

Watch these videos on how to test steel’s properties which may help you to select the types you require.

When we talk about tonnage or the term ‘tonne’ in the injection molding process, it means the injection molding press machine capacity regarding the clamping force it can exert. It has nothing to do with the weight of the machine.

So, if you encounter a statement like “this mold requires a 120 Tonne machine,” it essentially means that the mold needs a press capable of exerting a minimum clamping force of 120 tonnes (metric tons, specifically) to hold the mold halves tightly shut during the injection molding process. This force ensures:

• Proper mold closure: Prevents molten plastic from leaking out under high pressure (known as flash).
• Dimensional accuracy: Maintains the mold cavity shape for precise part formation.
• High-quality parts: Minimizes warpage and other defects caused by insufficient clamping force.

It’s important to understand that injection molding machine capacity isn’t the only factor to consider when choosing a plastic injection molding press. Here are some additional key parameters:

• Shot size: The volume of molten plastic the machine can inject into the mold. This needs to be compatible with the part size and material selection.
• Injection pressure: The pressure applied to force the molten plastic into the mold cavity.
• Clamping stroke: The maximum distance the mold halves can travel during opening and closing. The size of the injected parts needs to be removed between the two halves of the mold when it is open.
• Platen size: The dimensions of the movable and stationary platens that hold the mold.

The allure of speed and affordability often leads to the question of soft tooling, particularly aluminum molds. While this approach might seem appealing at first glance, let’s delve deeper to understand why, in many cases, hard steel molds remain the preferred choice for the average plastic injection molding process:

Cost Considerations in China

In China, the cost differential between hard steel and aluminum molds is often surprisingly minimal. This eliminates the initial cost advantage that aluminum might seem to offer elsewhere.

Automated Process

Modern injection molding facilities leverage automation extensively.  While machining hard steel does take slightly longer due to its inherent hardness, the difference is typically measured in days, not weeks. This automation advantage significantly diminishes the time-saving argument for soft tooling.

Durability and Production Efficiency

Aluminum molds, by their nature, are less durable than their hard steel counterparts. This translates to shorter lifespans, more frequent replacements, and ultimately, higher overall costs, especially for high-volume production runs. Hard steel molds provide significantly more cycles, maximizing production efficiency and minimizing downtime for mold changes.

Part Quality and Precision

Soft tools can struggle to maintain the same level of dimensional accuracy and surface finish as hard steel molds over extended use. This can lead to part quality issues, increased scrap rates, and the need for additional finishing steps. Hard steel molds ensure consistent part quality throughout their lifespan, minimizing rework and maximizing yield.

Our Experience

We’ve been approached about soft tooling in the past, and after careful analysis, we’ve consistently concluded that hard steel molds offer the best overall value. Their durability, efficiency, and ability to deliver superior part quality make them the smarter long-term investment, even when considering the slightly longer machining times.

The Takeaway about Aluminum Molds

In China, the combination of readily available steel, efficient machining practices, and economies of scale often shrink the cost gap between hard steel and aluminum molds.  When you factor in the superior durability, longer lifespan, and higher production efficiency of hard steel molds, they often become the more cost-effective choice in the long run, even for initial production runs.
