Chemical fiber machine screw

Chemical fiber machine screw

The screw is mainly used for melt spinning of PET, PA6, PA66, PP and other slices. The design uses low temperature mixture element, good plasticizing performance. The use of professional processing technology, so that the screw, barrel manufacturing accuracy is higher, better linearity.
