wpc extrusion

1,extruder

a,material of screw and barrel 38CrMoAlA, It also undergoes the process of nitriding technics.

The depth for screw nitriding is 0.5~0.6mm, rigidity(HV)800~900, surface roughness rate Ra≤0.8um.

The depth for barrel nitriding is 0.5~0.7mm,rigidity over(HV)950, inner surface roughness Ra≤1.6um.

b,Gear box adopts driving of hard tooth and inclined tooth surface, the gear undergoes the cementite process of 20CrMoTi, the gear for distributor box adopts 38CrMoA1A nitriding process, the axle is made of 40Cr material. The pushing bearing for the distributor uses the haerbin bearing, which runs smoothly and stably.

c,Use shanghai electrcity machine co., ltd motor, power 110kw, normal production capability 80-150kg/h.

d,Forced feeding motor power: 2.2KW

f,Cooling method of the material barrel is air cooling, cooling method of screw is oil cycle cooling, cast aluminum heating ring.

g,The main motor uses England European speed control equipment, The permitted power ranges of main motor is ±15%, temperature controller uses the imported one from Japan RKC, the tolerance ranges ±1°C, the measuring components adopt thermocouple. The low-pressure device is bought from Ximenzi with good arrangement of wires, good division color and accuracy tab, which guarantee good quality.
