Injection Molding Series

We leverage advanced rheological simulation to customize screw geometries, ensuring optimal plasticization for modern super-engineering plastics. Our designs maximize mixing homogeneity while strictly controlling shear heat to prevent material degradation. By tailoring the profile to your specific polymer characteristics, we ensure stable shot weights and reduced cycle times. This precision engineering guarantees superior physical properties in your final molded products.

Specification

◎ Bimetallic Screw & Barrel

We master abrasive and corrosive environments by integrating advanced metallurgical technologies. Barrels feature Centrifugal Casting to create an inseparable alloy bond, while screws utilize PTA welding on flights and HVOF thermal spraying for total surface armor. We offer Tungsten Carbide-based alloys for extreme wear resistance and Nickel-Chromium-Boron alloys for superior corrosion protection. This dual-protection strategy significantly extends component life under the harshest processing conditions.

◎ Optical Grade Screw

Engineered for uncompromising clarity, our optical screws utilize low-compression ratios to minimize shear stress on PC, PMMA, and COP. We apply specialized plating to ensure ultra-smooth flow paths, preventing material stagnation and carbonization. Precise control over residence time eliminates black specks and yellowing issues. This enables stress-free molding for high-precision lenses and automotive display panels.
