Parallel Twin Screw Extruder Machine Parts SHJ75 Extruder Elements
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.
