Plastic injection molding machine screw and barrel series
Plastic injection molding machine screw and barrel series


Plastic injection molding machine series:
Professional equipment, precision production, all kinds of screw barrel are made of high quality alloy steel 38CrMoALA manufacturing, product after nitriding by the anion has a very high wear and corrosion resistance, and increased life expectancy and so on, can replace imported products. Strict implementation of the technical indicators are "JB/T8538-1997" and the ISO9002 standards.
Screw Type: Tapered, mutant, wave type, dual type, tapered, split type, separate type, exhaust type, pin type, variable type, mixed type, double, three, long type, granulation type.
Screw the compression ratio according to different products and different formulations of the design.
