Product Description
The screw is the main core component of injection molding and extrusion equipment. Its quality directly determines the final product quality. Our plasticizing screws perform multiple functions including conveying, melting, mixing, compressing, metering and exhausting plastics.
Screw Material Classification
- HPT Fully Hardened Powder Alloy Screw: Tungsten-cobalt powder alloy tool steel with overall hardness HRC65°, suitable for transparent products, precision items, and high-temperature corrosive plastics like LCP, PES, PPA with fibers.
- Double Alloy Screw: SACM645 and 38CrMoAlA base with tungsten carbide nickel-based alloy spray welding, surface hardness HRC60°, ideal for transparent products and engineering materials like PA6, PA66 with fibers.
- Electroplating Screw: SACM645 and 38CrMoAlA base with hard chromium, nickel, or titanium plating, hardness HRC60°, suitable for PC, PMMA, PET transparent materials and corrosive U-PVC plastics.
- Stainless Steel Screw: 9Cr18MoV special stainless tool steel with overall hardness HRC55°.
- SKD61 Screw: Hitachi SKD61 material with excellent toughness and torsion resistance.
- Ordinary Nitrided Screw: SACM645 and 38CrMoAlA base with nitride layer depth 0.5-0.8mm and overall hardness HV980~1080°, designed for processing PP, ABS, PS, AS, PVC and other common plastics.
Screw Segment Functions
- Feeding Section: Fixed groove depth for preheating, conveying and pushing plastic solids.
- Compression Section: Tapering groove depth for melting, mixing, shearing compression and pressurized exhaust.
- Homogenizing Section: Fixed groove depth for mixing, melt transportation, metering and maintaining stable flow rates.
