PA6 plastic injection process
PA6 is a translucent or opaque milky white crystalline polymer. It has good thermoplasticity, light weight, good toughness, chemical resistance and durability. Because of its good mechanical strength and rigidity, it is widely used in structural components, has good wear resistance, and is also used in the manufacture of bearings.
Injection molding process conditions
Drying treatment: Because PA6 easily absorbs moisture, attention should be paid to drying before processing. If the material is supplied in waterproof packaging, the container should be kept closed. Humidity is greater than 0,2%, it is recommended to dry in hot air above 80 degrees for 16 hours. If the material is exposed to air for more than 8 hours, it is recommended to perform vacuum drying at 105 degrees for more than 8 hours.
Melting temperature: 230-280.
Mold temperature: 80-90. For thin-walled, long-process plastic parts, a higher mold temperature is also recommended. Increasing the mold temperature can increase the strength and rigidity of the plastic parts, but reduce the toughness accordingly.
High-speed injection speed.
The chemical and physical properties of PA6 are very similar to PA66. The melting point of PA6 is lower and the process temperature range is very wide. In order to improve the mechanical properties of PA6, various modifiers are often added, and glass is the most common additive. For products without additives. The shrinkage of PA6 is between 1% and 5%. Adding glass fiber additives can reduce the shrinkage to 0.3%.
