Custom single screw barrel designed for granulation extruder machines, engineered for optimal performance in plastic processing applications.

The screw serves as the core component of injection molding machines, determining final product quality through its plasticizing functions including conveying, melting, mixing, compressing, metering and exhausting capabilities.

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 fiber.

SACM645 and 38CrMoAlA base material with tungsten carbide nickel-based alloy ion spray, surface hardness HRC60°, ideal for transparent products and engineering materials like PA6, PA66 with fiber.

SACM645 and 38CrMoAlA base with hard chromium, nickel, or titanium electroplating, hardness HRC60°, suitable for PC, PMMA, PET transparent materials and corrosive U-PVC plastics.

9Cr18MoV special stainless tool steel with overall quenching and hardening, hardness HRC55°.

Hitachi SKD61 material with special processing for enhanced toughness and torsion resistance.

SACM645 and 38CrMoAlA base with nitride layer depth 0.5-0.8mm, overall hardness HV980~1080°, designed for processing PP, ABS, PS, AS, PVC and other common plastics.

Fixed screw groove depth responsible for preheating, conveying and pushing plastic solids, ensuring plastic begins melting by section end.

Tapering screw groove depth for melting, mixing, shearing compression and pressurized exhaust, where plastic completely dissolves and volume shrinks.

Fixed groove depth for mixing, melt transportation, and metering while maintaining uniform temperature and stable flow rate.

Our technical indicators include conditioning time 72H, tempering hardness HB260-290, gas vacuum nitriding time 168H, and nitride hardness HRC62-65°, ensuring consistent performance and durability.
