Brief introduction:
 
Screw is mainly used for PET, PA6, PA66, PP and other slices of melting spinning. The design uses low-temperature mixing elements, plasticization performance is good.
 
The use of professional processing technology, so that the screw, barrel manufacturing accuracy is higher, the straight line is better.
