Multi Shot Moulding
Plastic injection molding is one of our specialties. We specialize in multi-shot and two-shot injection molding. Using this method, you can mold custom plastic parts in one operation with two or more plastic resins or colors. Our company has extensive experience in designing and building high-quality injection molds for multi-shot and two-shot injection molded plastics.
Advantages
In multi-shot and two-shot custom plastic injection molding, plastic polymers from two or more injection units are applied through independent nozzles on one plastic injection molding machine to produce custom plastic parts such as soft-grip handle inserts, multi-colored parts, dashboard or instrumentation, or parts with molded seals, flexible hinges, or movable components.
The multi-shot and two-shot plastic injection molding technology enables:
- Multi-color, multi-material and multi-component parts
- New and wider range of designs
- More complex parts and reduced cost
- Production, handling and assembly efficiencies and savings
- Reduction of multiple and secondary operations
- Lower part cost
- Enhanced product features and appeal, including tactile, ergonomic and aesthetics
- Improved part and end use product integrity and quality
- Elimination of secondary process for logos, graphics and text
