Spray coating processing SPRAY PROCESSING
Screw wear-resistant coating—sprayed tungsten carbide
Screw for Plastics Machinery—Thermal Spraying and Coating Protection Area: The portion of the screw where material is pushed forward. Operating Condition: Material wear. Solution: Supersonic Thermal Spraying Method. Coating Material: WC/Co. Enhancement Effect: Extends service life by 1–2 times compared to conventional heat treatment. Processing Technology: In response to the specific requirements of various plastic products, most advanced engineering plastics currently in use contain additives such as flame retardants, glass fibers, calcium carbonate, and modifiers, which accelerate corrosion, wear, and shorten the service life of the barrel and screw. This process ensures that the sprayed alloy layer remains firmly bonded, free from cracks and porosity, and strictly controls issues such as workpiece deformation. Technical Specifications: Application: Extruders, Plastic Extruders, Extrusion Machinery. Screw Diameter: Φ15–Φ360. Length-to-Diameter Ratio: L/D = 15–45. Overall Hardness: HRC 58°–68°. Nitriding Depth: 0.4 mm–0.7 mm. Straightness: 0.015 mm–1000 mm. Screw Types: Gradual Transition Type, Step-Type, Wave-Type, Barrier-Type, Double-Barrier Type, Tapered Type, Splitter Type, Separator Type, Venting Type, Pin-Type, Hybrid Type, Double-Head, Triple-Head, Multi-Head, Granulation Type, etc. Applicable Materials: Common plastics, PA, PP, PC, PE, ABS, AS, PS, PVC, PMMA, LCP, PBT, PET, PPC, PPS, PAR, PO, magnetic powders, ceramic powders, aluminum-magnesium powders, iron powders, bakelite powders, and other engineering plastics.

Product Description
Screw wear-resistant coating—sprayed tungsten carbide
Plastic machinery screw
Protection area: The portion where the screw pushes the material.
Working condition: Material wear
Solution: Supersonic spraying method
Coating material: WC/Co
Enhanced effect: 1-2 times longer than the original heat treatment lifespan
Processing technology:
In response to the demands of various plastic products, most of the ultra-engineering plastics currently in use contain additives such as flame retardants, glass fibers, calcium carbonate, and modifiers, which lead to rapid corrosion, wear, and shortened service life of the barrel and screw. This process ensures that the sprayed alloy layer remains firmly bonded, free from cracks and porosity, and strictly controls issues such as workpiece deformation.
Technical indicators:
Applications: Extruders, plastic extruders, extrusion machinery
Screw diameter: Φ15 – Φ360
Aspect ratio: L/D = 15–45
Overall hardness: HRC58°-68°
Nitriding depth: 0.4mm–0.7mm
Straightness: 0.015 mm – 1000 mm
Screw types: gradual, stepwise, wavy, barrier, double-barrier, conical, split-flow, separate-flow, vented, pin-type, hybrid, double-head, triple-head, multi-head, pelletizing, and others.
Applicable materials: Common plastics, PA, PP, PC, PE, ABS, AS, PS, PVC, PMMA, LCP, PBT, PET, PPC, PPS, PAR, PO, magnetic powder, ceramic powder, aluminum-magnesium powder, iron powder, bakelite powder, and other engineering plastics.
