Machine Specification

Parallel Twin Screw Extrusion Barrel For TPU TPE TPO POE EVA PP PE PS PA PET Plastic Pelletizing Machine

Screw material :38CrMoAl, stainless steel (316, 304, 9Cr18Ni9TA) Nitride layer depth: 0.5-0.8 mm Hardness of nitriding: not more than 2 Surface roughness: Ra 0.4 um Screw straightness: 0.015 mm Hardness of hard chrome plating after nitriding: >950HV

Heat Treatment

1. Nitriding treatment 

2. Electroplating hard chromium layer 

3. Spray corrosion-resistant and wear-resistant bimetal layer

Twin Screw Processing Technology

The raw material of the screw is 38CrMoAIA, the hardness is HB280-30, the surface plasma surfacing of nickel base alloy, the thickness of the alloy is 0.8-2.0mm, and the hardness is HRC55-65. After finishing, the whole product is nitriding, the nitriding depth is 0.5-0.8mm, and the surface hardness is HV900-1050.

Parallel Twin Screw Extrusion Barrel

The extrusion part of the barrel adopts the spray welding alloy process, the thickness of the alloy is 0.8-2.0mm, and the hardness is HRC55-65, which effectively prolongs the service life.

Screw Cooling Treatment

After the screw is processed, it can not be placed directly beside the screw. It should be cooled down slowly to maintain the temperature.

Packaging and shipping Requirement For Double Alloy Treatment Conical Double Screw Barrel

Screw and barrel to pack by steel frame, not to easy to be broken in shipping.

Also, can packed by plywood as you like.
