What's the use of plastic and fiber?
PA is nylon, with good fluidity. When injection molding, it is easy to get rough edges.After adding glass fiber, the shrinkage rate can be reduced, the dimension stability can be improved, and the rigidity and the mushroom resistance can be enhanced.However, the injection pressure required after the addition of fiber will also increase, and the material requirements of the mold kernel are also higher, requiring stronger steel.
