Product details
Technical indicators:
Material used for the screw tube:
Cold feeding rubber screw and barrel: Specification: Ø 40- Ø 300MM
Length to diameter ratio: L/D=8-20
Hot feeding rubber screw and barrel: Specification: Ø 30- Ø 250MM
Length to diameter ratio: L/D=4-8
Pin machine rubber screw and barrel: specification: Ø 60- Ø 250MM
Length to diameter ratio: L/D=12-18
Screw type:
Different plastic properties allow for the selection of screws with different structures, which can enhance the plasticizing effect. Gradient, mutation, wave, barrier, dual screen, splitter, separation, exhaust, pin, hybrid, double head, triple head, multi head, etc.
