Automotive Industry: Polyamide Granules are used to manufacture small engine-related brackets, door lock assemblies, air conditioning ducts, fuel pump housings, wiring harness connectors, and instrument panel frames, where good strength and dimensional stability are required.
Electronics and Electrical Appliances: Power outlets, terminal blocks, coil frames, switch housings, circuit breaker bases, and power tool housings.
General Machinery: Small gears, bearing housings, pump body components, sprockets, instrument housings, and wear-resistant small transmission parts.
Others: Bathroom fixtures, load-bearing furniture components, and small outdoor hardware and plastic structural parts.
High rigidity + low deformation: Glass fiber forms a skeleton, significantly reducing thermal expansion and contraction, making it suitable for precision structural parts;
Enhanced Heat Resistance: Heat resistance is increased by nearly 80°C compared to pure PA6, making it suitable for components operating in high-temperature environments;
Stable Molding: Modified coupling process results in minimal fiber floating and easy injection molding, enabling high-volume mass production;
Optional Modifications: Heat-resistant, impact-modified and cold-resistant, UL94-V0 flame-retardant, and low-warpage specialty grades.
Molding Process: Injection molding is preferred
Barrel Temperature: 240–270°C
Mold Temperature: 70–90°C
It is recommended to dry the raw material at 80–100°C for 4–6 hours to remove moisture and prevent bubbles and silver streaks in the finished product.
