1. Product introduction
All kinds of screw and barrel produced by the company are made of high quality nitride steel (38CrMoAlA), refined by quenching and tempering, forming, qualitative, nitride (or spray welding double alloy), fine grinding and polishing. And the use of Europe and the United States of the latest technology and processing testing equipment carefully made, strict quality control, to ensure the accuracy and quality of products, and has a long service life and good wear and corrosion resistance. The rubber material must be heated, and the feed is uniform, stable, constant speed, the temperature of the material is kept at 50 ~ 70℃. Its screw is short, thread groove is deep, can be continuous extrusion, simple operation, high production efficiency, extrusion product shape is stable.
