Grooved bush Extruder
The extruder can be equipped with straight grooved bush or helical grooved bush on request. The screw and barrel have higher surface hardness, excellent wear resistance, and can withstand long-term friction and chemical corrosion. The screw can diverse mixers. The mixers can be maddock mixer, spiral maddock mixer, pin mixer, pineapple mixer and etc. The screw and barrel reduce shear heat, avoid local overheating of the melt, accurately control temperature, and prevent material degradation; reduce energy consumption and achieve significant energy savings, have stable and consistent melt quality, ensure articles’ quality while increasing output. We have more experience to make diverse types of screws and barrels. They are suitable for LDPE, HDPE, UHMWPE, PP, PVC, PA, PETG, PCTG, EVOH and etc. We can quickly design and manufacture customized screws and barrels, with higher quality, shorter lead time and more reasonable prices. Welcome to inquire!
