Product Summary

Our 38CrMoAl nitrided injection molding screw and barrel is designed for general plastics processing. With a nitrided hardness of HV850-1000 and a case depth of 0.45-0.7mm, it offers excellent wear resistance and plasticizing effect. Applicable for automotive, electronics, and toy manufacturing industries.

Key Selling Points

• High Wear Resistance: Nitrided hardness HV850-1000 and case depth 0.45-0.7mm ensure long service life under normal processing conditions.
• Precision Straightness: Screw straightness ≤0.015mm guarantees stable plasticizing and consistent product quality.
• Low Brittleness: Nitrided brittleness less than Grade 2 minimizes risk of cracking during operation.
• Surface Smoothness: Surface roughness Ra 0.4 reduces material adhesion and improves melt flow.
• Certified Quality: ISO9001:2015 certified manufacturing process ensures reliability.
