Classification of screw barrels

- Sep 01, 2018 -

Nitrided screw barrel (injection, extrusion, extrusion)

The material is made of high quality alloy steel (38CrMOALA) or chrome molybdenum alloy steel black cross (SACM645). It is refined by quenching, shaping, forming, fine grinding, surface nitriding or spray welding alloy (bimetal) and polishing. High wear resistance and corrosion resistance.

Technical indicators

Production use: injection molding machine / bakelite machine for injection molding machine / bakelite machine / extrusion machine / blow molding machine / blown film machine / granulation machine / extrusion machine / pipe machine / Sheet machinery / wire and cable

Effective length: 12000mm

Nitriding depth: 0.4mm-0.7mm

Nitriding hardness: HRC55°-58°

Straightness: 0.015mm-1000mm

Scope of application: ordinary plastic, PP, PC, PE, ABS, AS, PS, PVC, PMMA, etc.

Building block parallel twin screw barrel

   High-strength alloy steel, W6Mo5Cr4V2 or 38CrMoALA is nitrided. Wear resistance and corrosion resistance.

   The principle of “building block type” can be used to combine the length to diameter ratio of the unit and the internal spline form. The whole screw can be randomly combined according to different requirements by various specifications of "screw sleeve" and "kneading block" components. In use, it fully demonstrates flexibility and economy. The perfectly combined screw elements can achieve the effects of conveying, compressing, venting, plasticizing, dispersing, self-cleaning and even discharging of materials during work. The product has undergone rigorous testing to ensure processing accuracy.

Dongguan Huahong Plastic Machinery Factory has advanced processing equipment and technology, and has the ability to process various types of thread components.

Cone flat twin screw barrel

1. Material: 38CrMoALA, nitriding treatment, surface hardness: HRC55°-58°, nitride layer depth: 0.5-0.8mm

2, material: substrate 38CrMoALA, the surface of the spiral edge is made of double alloy imported alloy steel. After special treatment, it can effectively improve the wear resistance of the barrel screw and improve the applicable life.

Technical indicators

Production use: extrusion machinery, conical double screw tube, parallel twin screw barrel, modular double screw barrel

Nitriding depth: 0.4mm-0.7mm

Nitriding hardness: HRC55°- 58° or more

Straightness: 0.015mm/1000mm

Chrome plating: 0.02mm-0.20mm

Scope of application: ordinary plastics, PP, PE, ABS, PVC, raw materials, production of pipes, profiles, sheets and other products
