High Quality Twin Screw Barrel Plastic Extruder And Screw Barrel For PVC Machine
1. Product Application
Using machining center finishing, reasonable processing technology, advanced testing equipment, to ensure that the processing accuracy of each product.
Twin-screw extruder screw element:
a. convenient interchangeability by agile combination.
b. fulfill efficient self-cleaning, transmission, compounding, pressure-forming and etc.
c. made of high tool speed W6Mo5Cr4V2, or anti-corrosion steel 38CrMoAlA by speed treatment.
The flexible modular principle is realized with screw barrel sections from the wide range of different designs possible. Fast, intensive and uniform heating of the screw barrel section is ensured by electrical heaters. The barrel sections are cooled with water by means of an internal bore system with bores arranged close to the inside barrel wall.
