The Static Mixer for Injection Molding Nozzle is a precision, reusable metal mixing device designed for installation inside the injection nozzle (shooting tip) of an injection molding machine. Its primary function is to perform final-stage homogenization of the molten polymer immediately before it enters the mold cavity, effectively eliminating defects caused by uneven temperature, viscosity, or color dispersion.
| Feature | Benefit |
|---|---|
| Eliminates Color Defects | Resolves color streaks, spots, and uneven tones by achieving superior dispersion of color masterbatch. |
| Reduces Material Costs | Saves 15-25% of color masterbatch usage and allows for a higher percentage of regrind/recycled material. |
| Enhances Product Quality | Reduces internal stress, warpage, and sink marks, improving dimensional accuracy and mechanical strength. |
| Shortens Cycle Time | Reduces melt back pressure by 10-20% and lowers melt temperature by up to 10°C, directly shortening cooling and overall cycle times. |
| Minimizes Material Waste | Optimizes flow for faster color/material changeovers; select models include filtration to protect molds from contaminants. |
Unlike dynamic mixers, this device has no moving parts. It utilizes a series of stationary elements inside the nozzle to continuously split, reorient, and recombine the melt flow. For example, using the proven ISG (Interfacial Surface Generator) technology, the melt is divided into multiple substreams at each element, creating an exponential increase in layer count (e.g., up to 128 layers after 3 elements). This achieves thorough mixing within a very short length, under high temperature (up to 350°C) and high pressure (up to 150 MPa) conditions.

Eliminating flow marks, clouding, and splay marks on cosmetic parts.
Improving mechanical strength and consistency for glass fiber-reinforced components.
Enabling higher regrind ratios for cost-sensitive, non-critical parts.
Ensuring color consistency for multi-cavity molds.
Processing LSR where uniform mixing and drool-free shut-off are critical.
We provide engineering support to precisely match the static mixer design to your specific material, machine tonnage, and part requirements. Our solutions focus on achieving the lowest possible pressure drop while delivering maximum mixing efficiency, ensuring you gain productivity and quality without overloading your injection unit.
Please distinguish this reusable metal mixing nozzle from disposable plastic mixer tubes used for two-part adhesives. They are not interchangeable in terms of material, pressure rating, or application.
