PP water pipe connection,PA connection, Plastic connection

Features: 1. Crystalline materials, hygroscopicity small, vulnerable to financial rupture, long-term contact with the thermal decomposition of metal.
2. Good liquidity, But contraction scope and value of contraction, prone to shrinkage. Dent, deformation.
3. cooling speed, Gating system and the cooling system should slow cooling, and attention to the molding temperature control. Liu Wen significantly lower directional orientation. Low-temperature high-pressure particularly obvious, Mold temperature below 50
