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.

Optimized flow channel designs for various resin types, featuring superior high-pressure resistance and thermal stability.
Screw Tip Set / Three-piece Set
Consists of the Screw Head, Check Ring (Non-return Ring), and Seat (Spacer). The precision-engineered non-return mechanism prevents melt backflow and ensures high repeatability in injection dosing.
Barrel Head
Provides a high-rigidity support structure for the injection unit, ensuring precise alignment between the injection unit and the mold.
