What Is Injection Molding
Injection molding is a production method used to manufacture plastic parts by injecting molten plastic into a preformed metal mold. The molten plastic is injected at a predetermined temperature and pressure and left to cool. When it has solidified and adapted the shape of the mold, it is ejected as a formed part.
Types of Injection Molding
The typical injection molding process can be used to produce a wide variety of parts. However, there are enhanced types of injection molding that can be used to add design features to a part.
Insert Molding
Insert molding involves placing an insert or substrate into the mold cavity before injecting it with molten plastic. The insert can be made of metal or any other material that can withstand the temperature and pressure used in injection molding.
When the molten plastic is injected into the cavity of the mold, it settles onto and around the substrate and bonds with it. The part formed would, therefore, comprise a fusion of plastic and metal. This type of injection molding is used to:
Increase the weight of the part
Achieve threads on a plastic part
Add cosmetic or functional value
Improve the IP rating of the part
Pros:
Bonding the parts during injection molding yields neater structures than assembling them later when they are already formed
It is cost-effective
It is faster than separate assembly
Cons:
It increases cycle times
An insert slightly increases the odds of defective outcomes
Overmolding
Overmolding is done in two stages. It begins with the part being formed through the typical injection molding process. Once it is complete and has cooled, the core of the mold is placed over it one more time. Another layer of molten plastic is injected into the cavity. Depending on the intended design, the second layer of injected plastic may cover the whole or only specific areas of the part that has been returned into the mold.
The second layer of molten plastic injected during overmolding can be of a different grade and color from the one originally used to make the part. However, the materials need to be chosen carefully to ensure that they can bond well together. Different thermoplastics also require to be injected at specific temperatures and pressure from others. These parameters would, therefore, have to be adjusted during the second injection molding procedure.
This type of plastic injection molding is used to:
Strengthen the structure of the original part
Add flexibility to rigid areas
Add functional features like grip
Blend colors
Encase one plastic part in another without using adhesives or connectors
Pros:
It makes it easy to combine different materials
It is faster, more convenient, and effective than manual two-step assembly
Overmolding offers more seamless connectivity when encasing one part in another
Cons:
It increases cycle times
Multiple colors may not always blend with consistency
The Injection Molding Process
First, the part is designed in detail including precise dimensions and other structural specifications. Prototypes are then made to provide a more tangible sample of the part. The goal here is to examine the structure and test it for stability, functionality, and aesthetics. If there are any errors or modifications to be made to the design, the prototype would be reconfigured and printed for a second evaluation. This is done until the design is perfected.
Once the part design is complete and approved, mold-making which is also known as tooling can begin. A mold is a structure made of steel or aluminum. It has two parts: a core and a cavity; the core is solid but the cavity is hollow. Both are designed to match every detail of the part design. Their dimensions, curves/corners, rifts, or ridges are all made in likeness to the part that is to be manufactured. It takes high precision to make the perfect mold design and the process can take several tries.
When the mold is made, it is connected to an injection machine system, and the injection molding process proceeds as below:
A hopper is loaded with thermoplastic material which is gradually loaded into a barrel and melted.
Hydraulic or electric presses close the mold by pressing the core onto the cavity with great force.
The nozzle of the injection machine injects the molten plastic into the mold cavity at a predetermined high pressure and temperature.
After injection, the molten plastic cools and takes in the shape of the mold.
When it achieves the right cooling temperature and solid form, the mold opens along the injection mold parting line and ejector pins carefully push out the formed part.

Applications of Injection Molding
Medicine
The production of medical devices is complex and strictly controlled by regulatory authorities. Every proposed design for a medical device, therefore, has to be rigorously tested for functionality and safety. Often, multiple modifications also have to be made before the part is approved for production.
Injection molding is used to make accurate prototypes and preliminary samples of medical devices before they are approved. It is fast, affordable, and allows for modifications to be made over multiple tries until the design is perfected. We have in-house experts that are well-versed with medical device stipulations. Reach out to us and let us help you make your medical device the best it can be.
Bucket
For bucket molds, the most important factor to consider is the consistency of wall thickness because uneven wall thickness will result in molding injection failure after a certain period. This requires high accuracy tools throughout the manufacturing. FOW Mould’s tooling machines are of high precision which ensures the accuracy of the molds, thus lengthen the mold life.
Other than wall thickness, the cooling system also plays a vital role in the upcoming molding injection period. The cooling system must be designed based on the bucket specifically. Improper cooling water lines might affect the efficiency of the whole injection molding process. With FOW’s 10 years experience in bucket mold, we are able to avoid mistakes and offer you the most reliable mold-making service.
Warehouse & Storage
In Warehouse & Storage, crates and pallets are widely used. Molds for crates and pallets are relatively large, so the manufacturing cost might be higher. At FOW, when designing molds for these products, we conduct a MoldFlow analysis to predict any possible failures, which guarantees in the success of crate mould design and manufacturing. Over the years, FOW has gained rich experience in the design and manufacturing of moulds of crates and pallets, they now:
- Lighter in weight & smaller in size
- More compact in structure
- Have better usage for resins
- Reduce cycle time
Baby Product
Pediatric experts recommend that baby toys, furniture, and other equipment be made of smooth, non-corrosive, and lightweight materials. Plastic fits this bill perfectly and this is why it is used for most baby products. They are produced using injection molding because it makes it possible to reiterate one design countless times. Moreover, injection molding processes like overmolding make it possible for baby products to be made colorful and seamless without screws and other risky connectors.
We have a vast catalog of eye-catching designs and color combinations that would have babies cooing for your products. Our resin options can also be curated to achieve the highest standard of baby-friendly products.
Furniture
Plastic furnitures combine the features of comfort, cost-effectiveness and style. When designing a chair, for example, weight load is the first priority because this determines whether this is a safe and comfortable chair. To achieve this, our product designers must work closely with our clients to understand the needs of the target market and pass important information onto our mold designers. Besides weight load of the chair, we also need to consider whether each chair is stackable. This requires our product designers and mold designers to work together to develop a safe and comfortable that’s stackable.
Automobile
FOW Mould also has rich experience in automobile parts. For automobile molds, accuracy is the one thing that needs extra attention. All of our mold parts are processed by high precision machines, thus our injection molded parts are within a specific tolerance rate as our clients require.
Before proceeding to the mold-making period, our engineers run analysis on the product design and mold design, preventing any possible mistakes.
Home Appliance
Most home appliances are injection molded nowadays. To ensure a product’s quality, we need to put more attention to product design and mold trial in the final step. Product design is important because it has direct influence on product performance and the product life. Our product designers work closely with our client to confirm each functionality and detail, reducing the possibility of failures.
To further ensure product quality, we run mold trials for each project. We calibrate the mold until all the demands have been met.
