Using the world's advanced coating technology, to create high wear
and corrosion threaded element products.
High-performance, high wear resistance of the screw element, can
significantly improve product quality and consistency effectively
reduce the machine to replace the screw element frequency, will
minimize production costs.
*convenient interchangeability by agile combination.
*fulfill efficient self-cleaning, transmission, compounding,
pressure-forming, etc.
*made of high tool speed W6Mo5Cr4V2, or anti-corrosion steel
38CrMoAlA by special treatment.
*They are essential and key part of extruders for material to transmission, shearing and plasticization.
