Technical parameters of high quality and efficient rubber machine
◆ Nitride layer depth: 0.5-0.8mm
◆ Nitriding hardness: HV≥950
◆ Nitride brittleness: ≤ secondary
◆ Surface roughness: Ra ≤0.4um
◆ Straightness of screw: not more than 0.015mm
◆ The hardness of the chromium plating layer on the surface after nitriding: ≥950Hv, the screw is corrosion resistant after plating.
◆ Dual alloy hardness: HRC55-62; barrel alloy length is more than 600mm, using a unique process, the alloy layer is inlaid firmly and does not fall off.

◆ Dual alloy depth: ≥2mm
1. Do not start the machine when the screw does not reach the preset temperature.
2, to prevent metal fragments and debris from falling into the hopper, if processing recycled materials, you need to add a magnetic hopper to prevent iron filings from entering the barrel.
3. When using anti-salin, make sure that the plastic in the barrel is completely melted, so as not to damage the transmission system parts when the screw is retracted.
4. When using new plastic, the remaining material of the screw should be cleaned.
5.When the temperature of the molten plastic is normal, but the black spots or discoloration of the molten plastic are continuously found, the rubber screw should be checked.
6. During processing, try to plasticize the material as much as possible, do not allow metal foreign matter to be mixed into the material, and reduce the screw torque.
