Extruder screw barrel application: Single screw extruder screw types and uses: ordinary type, gradient type, sudden change type, mixing type, separation type, pin type, exhaust type, barrier type, split type, wave type, The above screw types of acceleration type are suitable for spinning, granulating, drawing, blown film, extrusion header, foaming, extrusion, sheet extrusion, etc.
38CrmoALA ），经过可调质定性、表面氮化、抛光等工艺精工制作，具有精密耐磨之特点。 The material of the product is made of high-quality gold-containing steel ( 38CrmoALA ), which is precision-made by adjustable quality and qualitative, surface nitriding, polishing and other processes.
3-5 倍。 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. .
Tips: In order to avoid purchasing risks, it is recommended that you confirm the supplier's qualification and product quality before purchasing the product.
