Material performance:
Tough, wear-resistant, oil-resistant, water-resistant, anti-enzytic, but absorbent

Nylon 6 has good elasticity, high impact strength and high water absorption.

Nylon 66 has better performance than nylon 6, high strength and good wear resistance

Nylon 610 is similar to nylon 66 but has low water absorption and low stiffness

Nylon 1010 is translucent, with low water absorption and good cold resistance.

Suitable for making general mechanical parts, wear-resistant parts, transmission parts, and parts such as chemicals, electrical appliances, meters, etc.

Molding performance:
1. Crystallized material, the melting point is higher, the melting temperature range is narrow, the thermal stability is poor, the material temperature exceeds 300 degrees, and the residence time exceeds 30 minutes to decompose. It is easier to absorb moisture and needs to be dried. The water content should not exceed 0.3%.

2. Good fluidity and easy to overflow. It is advisable to use a self-locking nozzle and it should be heated.

3. The molding shrinkage range and shrinkage rate are large, the directionality is obvious, and shrinkage and deformation are likely to occur.

4. The mold temperature is selected according to the wall thickness of the plastic part in the range of 20-90 degrees. The injection pressure is selected according to the type of the injection machine, the material temperature, the shape of the plastic part, the mold casting system, and the molding cycle is selected according to the wall thickness of the plastic part. When the viscosity of the resin is small, the injection and cooling time should be long, and white oil is used as a release agent.

5. The form and size of the mold casting system, increasing the size of the runner and gate can reduce shrinkage.
