Product introduction

The role of Zhoushan high-efficiency extruder screw is to gradually change the rubber compound into linear motion along with the screw rotation motion, and to move towards the head, and cooperate with the fuselage to compress heat, soften and stir, and mix the rubber compound.

Zhoushan high-efficiency extruder screw technical indicators
Production use: for injection molding machinery / bakelite machinery / extrusion machinery / blow molding machinery / blow film machinery / granulation machinery / extrusion machinery / pipe machinery / sheet machinery / wire machines / cables machine
Processing range: inner diameter Ф20mm-Ф250mm
Effective length: 8000mm
Alloy composition: 88wc / 12c0.Crc / 25Nicr.XaloY108
Nitriding hardness: HRC58 ° -62 °
Alloy hardness: HRC60 ° -65 °
Zhoushan extruder screw is suitable for plastic range: suitable for all kinds of special engineering plastics such as glass fiber, plastic and PPA, PO, PPS, LCP, ABS fireproof, bakelite powder, magnetic powder, PC and so on. The dual alloy screw uses special metal powder to spray weld the alloy on the screw ridge portion, and can use different alloys and welding methods for screws with different functions. General plastic range: ABS, PP, PE, PA66, LCP, PA + GF, PET + GF, PBT + GF, PC + GF and other engineering plastics such as glass fiber.
The diameter of the screw is slightly smaller than the inner diameter of the steel sleeve of the fuselage, that is, there is a gap between the diameter of the screw and the inner surface of the steel sleeve, and the gap is generally controlled at 0.002 to 0.004 times the diameter of the screw. Too small clearance will cause the "screw" of the screw, causing wear, and even the phenomenon of stuck screw; too large clearance will affect the amount of rubber backflow, low production efficiency and product quality.
