Our injection molding machine screw barrels are engineered for high-performance plasticizing with outstanding wear and corrosion resistance. Designed to meet the strict processing requirements of thermoplastics like PP, PE, ABS, PC, PVC, PET, and engineering plastics.

✅ Key Features:

• Material options:

  • 38CrMoAlA (nitrided): Surface hardness HV ≥ 950, depth 0.5–0.8mm

  • SKD61/H13 (bimetallic): Surface hardness HRC 58–65, life span 2–3x longer than nitrided types

• Barrel inner surface roughness: Ra ≤ 0.4μm, ensuring smooth material flow

• Straightness tolerance: ≤ 0.02mm/m

• Length-to-diameter (L/D) ratios: Available from 20:1 to 30:1 depending on application

• Custom screw compression ratio: Designed based on plastic material and shot volume

🔧 Compatible With Global Brands:

Our screw barrels are 100% compatible with world-leading injection molding machines including:
Haitian, Engel, Arburg, Nissei, Sumitomo, Demag, KraussMaffei, BOY, and more.

📈 Performance Data:

• Average output increase: 8–15% after upgrading to bimetallic screw/barrel set

• Downtime reduction: Up to 30%, thanks to improved thermal stability and precision fit

• Working temperature range: Up to 400°C, suitable for high-temperature engineering plastics

🛠️ Applications:

Used in automotive parts, electronic housings, packaging, medical devices, and precision components production.
