And when you consider just the wide range of injection molding benefits, understanding why millions of companies in some of the most demanding industries in the world are using it for bringing their part designs to life.

But why is injection molding machine manufacturing so effective? And how does it work?

To find out, let’s dig into the subject and answer all of the important questions, including what it is, the process behind it, its main advantages, and how to choose the right service provider.

What is Injection Molding?

Injection molding, а type of molding, is a manufacturing process of using plastic or metals to manufacture a wide range of parts and items. Although injection molding history can be traced back to the 19th century, it still remains one of the best ways to produce complex parts while keeping expenses under control.

The injection molding machine uses custom-made molds to fill them out according to specifications, creating identical copies that can be customized in a variety of ways.

What’s more, as is a very versatile process, injection molding supports a wide range of materials and finishes, which makes it a popular option in countless industries with completely different goals and requirements.

Because of this flexibility, the injection molding machine manufacturing is even used for some of the most demanding manufacturing projects in the world, producing parts in aerospace, medical fields, and the automotive industry.

Whether you’re looking to produce a small number of parts for testing, or need a reliable method for producing large quantities of parts in a hurry, injection molding can be an ideal choice, especially when working with plastics.

What’s more, the unique process when manufacturing part with an injection molding machine also means that you can produce complex parts with intricate designs, which is not something that can be said about all manufacturing options out there.

The ability to manufacture large quantities of parts at an affordable cost also makes it ideally suited for the production of various commodities. In fact, it’s likely that quite a few of the household items that you have could have been produced using injection molding.

How Does Injection Molding Work?

Even though the injection molding process is complicated, it can actually be broken down into a few essential steps that help understand how it works and why it’s so effective.

The injection molding machine is made up of three main components, which are the feed hopper, the screw, and the heated barrel. This machine works by taking plastic powder or granules and manipulating it to shape it into a part according to the requirements and dimensions.

When the feed hopper receives the plastic granules, it then uses frictional action of the screw to create heat. Once the plastic reaches the correct temperature, it is then injected into the mold cavity, where it eventually cools and takes the shape according to the mold design.

If necessary, advanced injection molding techniques such as repeated injection can be used to create parts out of multiple materials. It’s also possible to use insert molding to add plastic parts over existing parts made out of other materials.

The basic principles behind the injection molding process may seem simple, but in reality, it is a very complicated process that requires the right equipment and the right expertise. However, when it is executed correctly, injection molding can consistently produce excellent results even for the most challenging manufacturing projects. 

What are main injection molding parameters?

Understanding and controlling key injection molding parameters is essential for ensuring high-quality production.

• Injection pressure is paramount, typically ranging from 500 to 1500 bar, to ensure proper material flow and mold filling.
• Mold temperature significantly impacts part quality, with precise control required to balance flow and cooling.
• Nozzle pressure is crucial for consistent material injection, while mold locking pressure maintains mold integrity against the force of the injected material.
• Recovery rate, determining the speed at which the material is prepared for the next cycle, influences production efficiency.
• Shrinkage rate is another critical factor, affecting the dimensional accuracy of the final product.
• Clamping force ensures the mold remains closed during the process, preventing defects.
• Screw speed affects material homogenization and injection consistency.

What are the Different Injection Molding Types?

Injection molding can be categorized into several types, each with unique characteristics and applications, highlighting the depth and flexibility of the process as a technique.

Thermoplastic injection molding

Thermoplastic injection molding is the most prevalent form of this manufacturing process. It involves melting plastic pellets until they are sufficiently fluid to be injected under pressure into a mold. This type is particularly favored for its reversibility; the plastic can be reheated and reused, which suits a wide range of consumer products including toys, automotive components, and household appliances. Its ability to quickly produce large volumes of parts makes it indispensable in sectors demanding high production throughput alongside consistent quality, such as the automotive and consumer electronics industries.

Thermoset injection molding

Another significant category is thermoset injection molding, which differs from its thermoplastic counterpart due to the chemical nature of the materials used. Thermosetting plastics, once cured by heat, become cross-linked and cannot be melted down again. This irreversibility imparts superior chemical and heat resistance, making thermoset injection molding ideal for producing parts that must withstand harsh environments, such as electrical insulators, high-heat automotive parts, and certain industrial applications.

Silicone injection molding

Silicone injection molding stands out due to its use of liquid silicone rubber, a material known for its flexibility, durability, and temperature resistance. This type of injection molding is crucial in the medical field for creating parts that must be sterile, such as valves, connectors, and various medical instruments. Additionally, its application extends to making soft kitchen goods, like baking molds and spatulas, which benefit from silicone’s heat-resistant and non-stick properties.

Metal injection molding

Metal injection molding (MIM) caters to applications requiring the strength of metal with the intricate detailing achievable through traditional injection molding. In this process, fine metal powders mixed with a binder are injected into a mold. Following molding, the binder is removed, and the part is sintered to achieve full density. MIM is particularly advantageous for producing small, complex metal components like surgical tools, firearm components, and automotive sensors, where precision and durability are paramount.

Rapid injection molding

Rapid injection molding is an important adaptation of traditional injection molding, designed to accelerate the development cycle and reduce the time from concept to production. This technique leverages automated design and quick-turn mold manufacturing to produce injection molded parts within a dramatically shortened timeline, often within days. This method is particularly beneficial for prototyping or small batch production where speed is critical.

In rapid injection molding, the process begins with the creation of high-quality molds using aluminum or other easily machinable materials, which significantly cuts down on the time required to produce the mold. Aluminum, being easier to cut and shape than the more durable steels typically used in conventional molds, allows for faster machining without sacrificing the essential features of the mold. The rapid tooling process not only accelerates production but also offers a cost-effective solution for trial runs, enabling engineers to test designs and functionality without committing to the expense of full-scale production tooling.

Pros & Cons of Injection Molding

Even though injection molding is one of the most effective manufacturing techniques that has many advantages, there are things that need to be considered before deciding whether it’s the right approach for you.

Just as with any manufacturing approach, some advantages and disadvantages can apply to different situations, and only by understanding them can you make an informed decision.

With that in mind, let’s go over some of the most significant pros and cons that injection molding can offer.

Pros

First, let’s go over the advantages of manufacturing with an injection molding machine.

Impeccable Precision

Because of the way that material is injected to and then shaped by the mold, the number of imperfections can be reduced to a minimum. That means that with every run, you can produce a part that is identical to the one preceding it, over and over again.

As you can imagine, this type of precision is important in almost all industries, and especially in those that can’t compromise on quality, which is why injection molding is popular in highly-demanding fields like aerospace and automotive.

Complex Details

As mentioned before, injection molding enables companies to produce even the most complicated mold designs, executing even the smallest of details with ease.

You can add multiple details to your mold design and rest assured that each of them will be made a reality by the mold.

Durability

Unlike most other production methods, injection molding provides advanced possibilities in terms of the durability and reliability of the plastic parts that are produced.

For instance, you can add fillers in the injection molds that are created, which can help reduce the density of the plastic material and make each part stronger.

Automation

One of the primary reasons why injection molding produces consistent results is that a lot of the actual manufacturing process can be automated.

That means that you can not only reduce the chances of human error to a minimum, but also have the machine produce parts at a consistent rate and a high fulfillment rate.

Cost Efficiency

For the most part, injection molding is one of the most cost-effective solutions for producing parts that you can find.

Even though the bottom line of your project will depend on the materials that you use and the complexity of the designs, when comparing it with other manufacturing methods, you will usually find that injection molding will deliver more for the budget that you can allocate.

Wide Range of Materials

If there’s one thing that injection molding really excels at, it’s the ability to customize the materials and finishes according to almost any type of requirements. You can choose plastic, thermoplastic rubber, chemical resistant plastics, biodegradable, and many others, so just be sure to figure out what you need from the part and you’ll have plenty of options.

You can also select almost any color imaginable, and can also choose from a wide variety of finishes, either for aesthetic or functional purposes.

Eco-Friendly

Finally, in a world where being conscious of the environment is more important than ever, injection molding can be useful because it produces almost no waste.

Every bit of material that isn’t used in the mold can be repurposed and used in future projects.

Cons

Now that we’ve looked at why injection molding is so effective, let’s look at some of its shortcomings to provide you a more well-rounded picture.

High Initial Cost

As we mentioned earlier, injection molding can be very cost-effective, especially for bigger production runs, since the cost of one part is relatively low.

However, before you can actually manufacture, you will need to design and create the mold itself, and that can take many hours and a lot of manpower to execute correctly. There are numerous factors that affect the final cost of injection molding.

Still, even though this process can be complex, once it’s done, you can use the mold to produce thousands of parts quickly.

Takes Longer to Get Started

Because of the fact that the mold needs to be designed and created, it’s understandable that this process will take time, and can sometimes take months to complete, depending on how complex your project is.

But even though the project of mold development can take time, once it’s done, the process becomes extremely fast and reliable. And if you know what you’re looking for and have prior experience, you can cut down on the time significantly.

Size Limitations

Although an injection molding machine can produce fairly large parts of up to around 60 cubic inches, if you need something bigger, you might have to choose another manufacturing method such as plastic fabrication.

Still, in most cases, it’s likely that your part will fall well within the parameters, so you should be fine.

What are the Applications of Injection Molding?

When producing parts, precision and cost-effectiveness are two of the most important considerations that most companies are looking for.

That’s why it’s not surprising that a process such as injection molding has become so popular and has been used both for smaller runs, as well as large-scale production of parts with tight tolerances.

We already talked about some of the high-tech industries that benefit from this manufacturing technology, but let’s look at a few more of the common injection molding applications that are very common, to see what types of items you could produce.

Food & Beverage

As we mentioned earlier, injection molding offers companies the ability to produce parts from a wide range of materials. And that’s very important in an industry such as food & beverage because it needs to comply with a wide range of regulations regarding the safety of food containers. With injection molding, you can use BPA-free and non-toxic plastics that are not only safe to come in contact with food but can also withstand temperature changes.

This, combined with the relatively low cost of production, makes injection molding ideal for producing parts such as food containers, beverage caps, filtering components, and much more.

Construction Parts

Another industry that uses injection molding technology is building and construction, where the custom-made and complex plastic parts play a vital role in the process of building houses and structures.

And oftentimes, these parts also have to meet strict requirements in terms of quality and fit.

For instance, when creating plastic parts for windows and doors, the parts must not only come out perfect but must also be durable, and have unique qualities for withstanding environmental factors.

Today, injection molding is even used to produce parts that can replace metal components, providing excellent performance for a much more affordable price.

Medicine

Because of injection molding, medical companies are able to produce vital tools and parts cheaper, which helps make healthcare more accessible to people all over the world.

Many of the integral medical devices such as heart pumps, various monitors, as well as a range of medical instruments all depend on the precision of injection molding, which makes the technology irreplaceable in the field.

What is the difference between injection molding and machining?

Injection molding and machining are two distinct methods of shaping materials.

Injection molding involves heating the materials until they liquefy, and then injecting them into a pre-designed mold. The material cools and solidifies, taking on the mold’s shape.

On the other hand, machining begins with a solid material block that is gradually shaped using sophisticated machinery. This subtractive process carves away the excess material until the desired object is formed.

While injection molding is ideal for mass production due to its repeatability, machining excels in creating complex, precision parts in smaller quantities.

What is the difference between injection molding and 3d printing?

When comparing injection molding and 3D printing, it is clear that they are two significant manufacturing methods, but they are not the same. We already know how injection molding function so let’s discuss 3D printing.

3D printing uses a digital blueprint to create an object layer by layer in an additive process. Although it may be slower and often pricier per part, 3D printing shines in the production of intricate, customized, or low-volume pieces. Its versatility allows for on-demand manufacturing and design innovation.

How to Choose Injection Molding Services?

Even though injection molding can be incredibly useful in a wide range of industries, in order for any of that to matter, you must choose a reputable and experienced services provider that can take your vision and turn it into reality.

But what are some of the things you should look for?

Well, for one thing, the company that you choose to work with should have the necessary experience of dealing with a range of injection molding projects. As you now understand, the process of designing and creating the mold can be challenging, so you need experienced specialists that can help you overcome any hurdles that you encounter.

In addition to experienced staff, the provider should also have the most cutting-edge injection molding machine technology because that plays a vital role in how precise the parts can be, how quickly they can be produced, and how long will it take to start the manufacturing process.

Finally, you should look for an injection molding services that can handle big projects. When you need to scale up production, you don’t want to have to look for a new provider simply because the company turned out to be incapable of doing larger runs.

What is Insert Molding?

Insert molding is a plastic injection molding technique that involves installing or merging inserts, especially metal, within an injection-molded part. This technology involves placing the insert in the mold cavity before pouring the molten plastic around the insert under high pressure. As a result, the insert becomes a solidified plastic part upon cooling.

Metal insert molding allows the manufacturing of strong, durable, and lightweight plastic products with metal components. Consequently, it is a widely popular and applicable process in different industries due to its high compatibility and effectiveness.

Common Insert Molding Materials

Injection molding is a versatile process compatible with a wide range of materials since it is ideal for merging two different components into one product exterior or top layer in insert molding. Thermoplastic and thermoset materials are primarily used in injection molding due to their strength, sturdiness, or good electricity flow.

• Thermoplastics: Polypropylene (PP), Nylons (Polyamides/PA), polycarbonate (PC), ABS, Polyethylene (PE) and Acetal;
• Thermosets: Polyester, Epoxy, melamine-formaldehyde resins, and urea-formaldehyde resins;
• Elastomers: Polyurethane, natural rubber.

Steps for the Plastic Insert Molding Process

The insert molding process is somewhat similar to conventional injection molding since it involves melting and injecting molten plastics into a mold. However, plastic insert molding involves loading inserts in the mold as the molten plastic floats into the mold cavity. Here is a stepwise to the plastic insert molding process.

1. Load Selected Inserts into the Mold

It would help if you considered the positioning of inserts within the molds when designing the molds for the process. It helps to ensure the insert maintains its orientation and position throughout the molding process. There are two ways of loading inserts into the mold: “automated insertion” and “insertion by hand.”

Two Methods for Loading Inserts into the Mold

Automatic insertion is more precise, consistent, and efficient. It uses robots or automated mechanisms that can resist high-temperature levels to load insert components into the mold. As such, manufacturers often benefit from faster turnaround times since the computerized machines are fast and can mold more parts per hour.

On the other hand, Insertion by Hand/Manual Insertion is ideal for low-volume injection molding since it involves loading the insert components into the mold by hand. Moreover, this procedure is more common than automated since the operator is always present to carefully inspect, package, and assemble the injection mold components, incurring lower additional costs. However, the insertion-by-hand technique may lack high precision and repeatability.

2. Inject the Molten Plastic into the Mold

You must use an injection unit to deposit the molten material into the mold under high pressure. The applied pressure forces the molten plastic to fill the mold evenly. As such, it pushes out air through the vents present in the mold, ensuring the plastic bonds firmly and entirely to the inserts.

3. Open the Mold and Eject the Molded Part After Cooling

While the molten plastic has filled the mold evenly, it would be best to maintain a set temperature to allow consistent solidification. You must maintain a holding pressure to mitigate potential shrinking effects while preventing backflow into the barrel. However, the mold opens when cooled and allows the removal of the insert-molded part.

4. Separate the Molded Part From the Sprues

Molded parts often get attached to the sprues that helped form them. These sprues are like structures or frames that ensure all components of the molded part are made. You must detach the molded part from the sprue to use the part. However, be more careful when separating the sprues to avoid damaging or affecting the molded part.

5. Post-Molding Operations

Plastic molds often require certain post-processing operations after molding before they are ready for the market. Amongst the common post-processing treatments widely used for inserting molded components are:

• Deburring: It involves using deburrers to remove excess material affecting the molded part’s physical properties.
• Heat Treatment: Heat treatment is effective for removing internal stress that can compromise the quality of the molded part. It usually involves subjecting the molded component to a temperature 10-20 °C lower than its deformation temperature or higher than the service temperature.
• Humidity Control: This treatment involves bathing molded parts in hot water of 80-100°C. It insulates molded parts from the air, increases moisture absorption, stabilizes size, and prevents oxidation.

Design Considerations for Insert Injection Molding

Although insert injection molding may seem straightforward, the process can be complicated. Here are some helpful design considerations for practical insert injection molding.

Examine the Cost/Budget

Injection molding cost is an essential consideration for cost-sensitive parts. Here, the cost includes the cost of acquiring inserts and contracting an operator. Also, the increase in price per unit that adding an insert would cause is another cost element to consider.

Identify Properties of Selected Insert

You need to know the properties of the inserts you choose for the intended application. The insert molding process involves extreme temperature and pressure. Therefore, your chosen insert must be able to withstand these extreme conditions during the process. As a result, you must examine the material of the insert, its dimensions, and surface finish to decide the ideal molding process.

Insert Location

The location of the insert is another major factor as it determines the forces that would act on it over time. Similarly, it would help to consider the intended application of the insert and the amount of plastic required to hold it in place when deciding the ideal location.

More importantly, ensure the insert remains in place throughout the process, as location changes affect the molding process and render the part unusable.

Narrow Gap between Metal Inserts

Maintaining a narrow gap between the metal part inserts in the injection molding design is advisable. It helps ensure the inserts are covered by the liquid plastic injected into the mold, facilitating a solid bond between metal inserts and plastic material. Therefore, it prevents voids and improves the insert molded part’s structural integrity.

Choose the Appropriate Material

During insert injection molding, choosing a suitable plastic material and insert material is essential. Choose strong and durable materials that bond perfectly with each other to prevent plastics surrounding the inserts from cracking.

Typical examples of these plastic injection molding materials include Nylon, ABS, Polycarbonate, and polyethylene. On the other hand, brass and steel are typical insert materials.

Use the Right Mold

Choosing the suitable mold for the insert molding process is another critical factor. It not only shapes the molten plastic but also holds the insert in position during the operation. Hence, use a well-designed mold that allows a uniform flow of molten plastic and ensures the insert remains in place throughout the molding process.

However, use a mold with rounded corners to ensure the free flow of molten plastic and prevent stress on the mold walls, often caused by sharp corners.

Advantages and Disadvantages of Injection Molding Insert

Insert molding has wide applications thanks to its many advantages. Here are some of the expected advantages of injection molding inserts:

• Injection molding insert minimizes assembly and labor costs since it eliminates post-molding assembly.
• These inserts for injection molding reduce the size and weight of molded products.
• Insert molding offers increased design flexibility, allowing product designers to be as creative as possible.
• The metal inserts strengthen the mechanical properties of the injection molded parts.

Even though injection molding insert offers a lot of benefits, here are some of its downsides:

• Designing a mold with inserts for injection molding is more costly and complex.
• Injection molding inserts material may be incompatible with the molding process due to differences in thermal expansion rates of inserts and surrounding materials.
• Defects may occur in molded parts and components due to the inaccuracy in positioning the injection molding insert during the molding process.
• Using inserts increases cycle time since the inserts must be accurately positioned in the mold before the process.

Applications of Insert Molding Parts

Insert molded components have a wide range of applications in different industries. Common industries that use insert molding parts include:

Automotive

Manufacturers in the automotive produce insert molding parts as an alternative to metal parts. These plastic insert molding parts are more durable and lightweight. Threaded fasteners, gears, and electrical sensors are common insert molding parts used in the automotive sector.

Consumer Electronics

Manufacturers in the consumer electronic industry often use insert molding to avoid using fasteners and solders during manufacturing. Typical examples of insert molding parts in this industry are digital control panels, knobs for appliances, assemblies, and electrical wires covered by rubber exteriors.

Medical Devices

The healthcare sector benefits significantly from inserting molding parts since plastic components are easier to sterilize. Manufacturers in the healthcare sector use the insert molding process to make different medical devices, including dental instruments, tubes, medical equipment components, prosthetics, medical enclosures, medical knobs, and surgical instruments.

Insert Molding vs. Overmolding Comparison

Insert molding vs. overmolding are different injection molding processes often used to produce molded parts that are similar in structure. Both techniques differ in the steps required to achieve the preferred result regardless of their similarities.

Insert molding is a unique technique that involves molding plastic material around a pre-formed insert placed in a mold—the plastic material bonds firmly with the insert to form a single part. Insert molding is a single injection molding process, very fast, and uses less materials

On the other hand, overmolding is a two-shot molding technique that involves molding a rubber-like plastic over another plastic. Overmolding is a twofold injection molding technique, making it more expensive than insert molding since it uses more material.

Moreover, manufacturers employ the insert injection molding process to produce molded parts with improved strength and structural integrity. Overmolding, however, adds comfort, aesthetic appeal, and protective layers to a product.
