Key Injection Molding Reference (Simplified for Practical Operation)
Drying: 80℃ for 4-6 hours (moisture content ≤ 0.2%); Barrel temperature: 270-285℃, Mold temperature: 70-100℃; Injection pressure: 80-120MPa, Cooling time: 20-40 seconds; Wear-resistant screw and barrel are recommended.
Summary of Core Advantages
Compared with halogen-containing flame-retardant PA66, it is more environmentally friendly, with lower smoke and toxicity and better insulation. Compared with non-flame-retardant glass fiber reinforced PA66, it has high safety flame-retardant redundancy, balancing strength and heat resistance. It is a cost-effective choice integrating “safety + performance + environmental protection” for high-end industrial scenarios.
