1. Rubber extruder, hot feeding extruder, cold feeding extruder
2. Version: XJ-115, 85, 65...
A) Screw is made by nitriding steel (38CrMoALA), Surface is under nitrogen treatment, thickness ≥ 0.55mm, Hardness is ≥ HRC62.

Hollow structure, Easy to control temperature, and no leakage after hydrostatic test, one hour -10kg/cm2.

B) Barrel is pin structure, axial drill cooling.

The lining bush of barrel also made by nitriding steel (38CrMoALA), after nitrogen treatment. Hardness is ≥ HRC66, and thickness ≥ 0.55mm.

C) Pin is made by 40CR

D) The materials of feeding roll is also made by nitriding steel (38CrMoALA), thickness of surface is ≥ 0.55mm, Hardness is ≥ HRC62.

The gear of feeding roll is made from 20CrMoTi, and surface is after carbrization, thickness 1.5mm, gain wear-resisting property.

6- Other instruction:

Lubrication of speed- ratio gear is grease

There is a cutter to scrape the rubber which stick on the roller

The base of extruder is connected with motor, and design reasonable, enough intensity and stiffness.

4- The water circulating pump is from Germany WILO.

5- CE, SGS, ISO9001 certificate.
