Brass Plastic Moulding Insert
A general-purpose brass insert engineered for embedding in a wide range of thermoplastic materials including ABS, polycarbonate, nylon, POM, HDPE, LDPE, PP, and PEEK. Features opposing diagonal knurling for exceptional resistance to both torque and tensile loads. Available in metric (M2–M12) and UNC/UNF thread sizes. Can be installed via heat-staking (using heated press tools that melt surrounding plastic), ultrasonic insertion, or direct mould-in during injection moulding. Common in automotive interior parts, sensor housings, GPS enclosures, PCB standoffs, and aerospace overhead compartment components.
Key Highlights

Material & Quality Assurance
Moulding inserts are manufactured from CDA 360 and CDA 361 free-cutting brass, selected for their exceptional machinability. The alloy composition provides good corrosion resistance and adequate tensile strength for fastener applications.
Usage & Installation Guide
The installation method depends on the host material properties and production volume. Mould-in installation provides the strongest bond; heat staking is preferred for post-moulding installation; ultrasonic insertion creates rapid and clean installations.
