What is Stack Molding?
Stack molding is a plastic injection molding process where a single injection molding machine produces multiple parts simultaneously in a single molding cycle. The stack mold itself consists of two or more molds mounted one above the other in a vertical stack. Stack molding is suitable for producing plastic parts from small precision components to larger parts with complex geometries.
Stack Molding Advantages:
- Increased production efficiency
- Reduced cycle time
- Improved part consistency
- Reduced material waste
- Reduced need for assembly and post-processing
