The material of the split type double alloy screw is made of high-quality gold-containing steel (38CrmoALA), which is precisely manufactured through adjustable quality and qualitative, surface nitriding, and polishing processes, and has the characteristics of precision wear resistance.
We can not only make samples and manufacture, but also design, survey and manufacture according to the special requirements of customers, or use bimetal repair work on old screws. The service life of bimetal screws is 3-5 times longer than that of ordinary nitriding screws. .
Single screw extruder screw types and uses: ordinary type, progressive type, sudden type, mixing type, separation type, pin type, exhaust type, barrier type, split type, wave type, acceleration type Silk, granulation, drawing, blown film, extruded header, foaming, extruded sheet, extruded board, etc.
