Insert molding is the process of fitting a preformed part that is often metal and then loaded into a mold where it is overmolded with resin creating the final functional product. It is pretty similar to injection molding. However, the difference lies in the fact that injection molding uses a resin that is injected into the mold using a high-pressure machine, while insert molding uses preformed parts or inserts.

Insert molding is a highly efficient process that produces high-quality parts at a lower cost than other methods. It allows the manufacturing of both small and large-volume production runs and can be used for one-of-a-kind or mass-production projects. The insert molding process offers many advantages to companies looking for high-quality parts at a competitive price.

High Strength and Stiffness
Insert molded products are typically stronger than conventional injection molded parts due to the strength of the metal inserts. This results in a better product that is less likely to break during use.
Good Surface Quality
Insert Molding processes produce smooth surfaces free of seams, wrinkles, parting lines, and other defects that can affect the appearance, durability, and performance of a product. With insert molding, you can get a high-quality product that looks great and functions well.
Smooth Surfaces and Close Tolerances
It allows us to produce parts with close tolerances and smooth surfaces without the need for expensive secondary operations like machining or grinding after molding resulting in a lower overall cost for the customer.
Lower Cost Than Other Methods
The insert molding process is a low-cost alternative to other methods, such as injection molding. The materials used for inserting molds are less expensive than those used for injection molds. This makes them ideal for small production runs and prototypes.
Быстрое время выполнения заказа
Injection molds often take weeks or months to manufacture and deliver. Our inserts can be delivered within days because they are made to order in our state-of-the-art manufacturing facility. You can also have multiple parts made at once, which reduces the number of tool changes required during production.
It can Be Used for Large or Small Production Runs
Our inserts are available in various sizes and custom shapes, that means you can opt to which one best suits your needs. They’re also available in a variety of materials, including steel and plastic, so you can choose one based on your application’s requirements.

We provide quality, large runs and insert molding examples and prototypes so you can better understand our products’ capabilities and what our process can do for your business advance in the world’s market.
Step 1: Design
The first step is to design the product. This includes creating a 3D model of the product and determining the dimensions, material, and color of the product. This way, we can create a prototype that is close to the final product as possible.
Step 2: Mold Making
The next step is to create the mold. This includes machining the mold from a block of metal or plastic. The mold must be designed so that it can be opened and closed easily. It must also be strong and durable to withstand the pressure of the injection molding process.
Step 3: Actual Insert Molding
Once the mold is created, the next step is to injection mold the product. This is done by injection molding the material into the mold. The material will then adjust to the shape of the mold and harden.
Step 4: Cooling and Removal
After the product has been injection molded, it must be cooled. This is done by placing the mold in a cool environment or by using a cooling system. Once the product cooled down, it can be removed from the mold.
Step 5: Post-Production Testing
After removing the product from the mold, it is time for post-production testing. This includes testing the product for strength, durability, and function. This way, we ensure that the product will work as intended and dseigned before it is shipped to the customer.
Step 6: In-House QA/QC Inspection
The last step is to inspect the product. This is done by our in-house quality control team. They will check the product for defects and ensure it meets all of the customer’s specifications.
Benefits of Insert Molding
With the increasing popularity of 3D printing, many people are wondering if insert molding is still a viable option. The answer is yes! Insert molding has many benefits that make it a great option for a variety of applications.
- Low Cost: An alternative to conventional molding methods, insert molding is less expensive because the materials used are less expensive.
- Fast Turnaround: Insert molds can be delivered within days, while it can take weeks or months to receive an injection mold.
- Precision: Insert molding can create products with tight tolerances and intricate designs. The precise nature of the process also makes it ideal for creating products with multiple components.

FAQs of Insert Molding
What are overmolding and insert molding?
Overmolding is the process of combining different materials into one single piece of plastic. It’s a good way to give your product a durable outer layer while preserving its aesthetics.
Insert molding is a similar process but with a few differences. In this case, an item is made out of metal or plastic and then inserted into another piece of metal or plastic that has been heated up to a high temperature. This allows for greater precision when designing parts and even more durability when it comes to wear and tear.
What is insert molding used for?
Insert molding can be used for several applications, including gears, seals, and even medical devices. However, the most common use is in automotive applications where there are high expectations regarding strength and durability as well as beauty. You might find inserts being used in gearboxes or transmissions on cars today – they provide extra support for the gear teeth so that they don’t get damaged during use or when coming into contact with other moving parts like bearings or clutches.
How does insert molding work?
Insert molding works by first creating a metal or plastic part that will be the insert. This part is then placed into a mold that has been heated to a high temperature. The insert is then held in place while the molten material is injected into the mold around it. Once the material has cooled and hardened, the insert is then removed from the mold, revealing a completed product that has the desired shape with the insert in place.
How long does insert molding take?
The length that it takes to complete an insert molding project will vary depending on the complexity of the design and the number of inserts that are being used. In general, however, you can expect the process to take a few hours to a few days.
Do you require a minimum order quantity (MOQ)?
No, we do not have a minimum order quantity. We are happy to work with you, no matter the size of your project.
