Parallel screw has reasonable structure, good plasticizing effect, high output, stable extrusion and many other advantages.
The arris surface of the parallel twin-screw is usually spray welded with special dual alloy, effectively extend the lifespan of the screw.
The load torque of the parallel twin-screw is large, but its energy consumption is low. During the extruding process of board or sheet, it can avoid flaws like black lines or yellow lines.
1. 38crMoAIA, hardening and tempering, nitrogen treatment. Surface hardness: HV≥900 nitriding layer thickness: 0.5-0.8mm
2. The 38crMoAIA arris surface of the screw is spray welded with special dual alloy, effectively extend the lifespan of the screw.
Application: common plastics, PP, PE, ABS, PVC, granules, tubular products, profiled bars, sheets, etc.
