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.
