Applications
Insert Molding for High-Precision and Complex Parts
Insert molding is a versatile manufacturing process that enables the production of complex and high-precision components. At GBM, we have extensive experience in insert molding and have successfully delivered a wide range of parts across various industries.
For example, we have produced microelectronic components such as connectors, switches, and sensors that demand high precision and tight tolerances. Additionally, we have manufactured automotive parts like gears, housings, and brackets that require exceptional strength and durability.


Material Selection For Insert Molded Parts
Insert molding typically involves the use of a plastic material combined with a metal or other material for the inserted component. The careful selection of materials is crucial to achieving the desired performance, strength, and durability for the final part.
Main Materials
Choose the main material for your injection molding product
We have extensive expertise in hundreds of plastic and other materials for injection molding, including single materials, mixed materials, modified materials, and rubbers. Our deep understanding of their physical and chemical properties ensures optimal material selection for your specific needs.
Additionally, with our robust supply chain system, we can source raw materials quickly and reliably, ensuring stable production and on-time delivery without disruptions.

Inserted Materials
Dare to imagine, dare to insert
Insert injection molding is most commonly used for inserting screws or studs, with brass being the preferred material due to its corrosion resistance, affordability, and ease of processing. This makes brass the most widely used insert material.
In addition, copper, aluminum, steel, hard dissimilar plastic parts, ceramics, glass, and plastic can also serve as insert materials. During product application, we carefully design the shape and structure of plastic parts based on the thermal expansion coefficients of different materials to ensure optimal performance and durability.
