What Is Insert Molding Service?
Insert Molding is a highly efficient injection molding process where pre-formed materials (often metal, ceramic, or plastic) are inserted into a mold cavity, and plastic or other material is injected to encapsulate the insert. This process is widely used to combine multiple materials into a single component, enhancing functionality and reducing assembly time.
Custom insert service is commonly used for manufacturing parts that require high durability, electrical conductivity, or multi-material properties. Industries such as automotive, electronics, medical devices, and industrial machinery often utilize insert molding for critical components.
Insert Molding Services Material
Inserts Molding Materials
The molding material or the resin is chosen based on the mold. We offer the following materials for insert molding process.
- Polypropylene (PP)
- Polyamides/Nylon (PA)
- Polycarbonate (PC)
- Acrylonitrile Butadiene Styrene (ABS)
- Polyethylene (PE)
- Polyurethane (PU)
- Natural Rubber (NR)
Insert Molding Material selection
The material used for injection molding inserts design can vary depending on the function of the part. Common choices include:
- Plastics: Nylon (PA), Polycarbonate (PC), Polypropylene (PP), and ABS are often used for their durability, chemical resistance, and cost-effectiveness.
- Metal Inserts: Stainless steel, brass, and aluminum are commonly used for their strength, conductivity, and corrosion resistance.
- Ceramic Inserts: In specialized applications, ceramics can be used for their heat resistance and electrical insulating properties.

FAQs of Insert Molding
How does plastic insert molding improve productivity?
By integrating inserts with plastic parts, insertion molding eliminates assembly steps and improves production efficiency, especially for mass production.
What inserts can I use for custom insert molding service?
Inserts can be metal (such as steel, aluminum, copper), ceramic, or hard plastics, depending on the strength, corrosion resistance, and other requirements of the final product. Don’t know how to choose, let the Jiangzhi to help you!
How long is the production cycle of insertion molding?
The production cycle of custom insert molding depends on several factors, such as mold complexity, part size, and production volume. Generally speaking, The single production cycle of insert molding is usually between 1 and 5 minutes, but this also needs to be adjusted according to the specific production conditions. In mass production, the cycle may be shorter, because the mold and equipment have entered a stable working state.
Does the insert move during insertion molding?
Is the insertion firmly attached to the plastic? Is there a risk of falling off?
In the Insert Molding process, the attachment of the insert to the plastic is usually very strong. By precisely controlling the mold temperature, injection pressure and cooling rate, we are able to ensure a strong bond between the insert and the plastic. To ensure the highest quality, we carry out rigorous quality testing on each product, including strength testing, adhesion testing and dimensional accuracy checks to eliminate the risk of falling off.
What are the similarities and differences between overmoulding and insert moulding?
Overmoulding involves injecting a material over an existing part to add a new layer, while insert moulding embeds a pre-made component, like metal, into a plastic part. Both processes combine materials to enhance functionality, but overmoulding adds a soft or protective layer, and insert moulding integrates parts for added strength or features.
