Parallel co-direction twin-screw extrusion system:
Screw, cylinder adopts “building block” structure, with good interchangeability, that piece of bad change that piece, not to the cone double screw as long as there is a little flaw to replace the whole root. Can be arbitrarily combined according to the different material processing technology; Cylinder selection of nitride steel, bimetallic materials, wear-resistant, Corrosion resistance, prolong service life; The thread element selects nitride steel, high speed steel, with unique processing technology, so as to ensure the normal teeth of the thread working section
