Stack molds are very common in custom plastic injection molding. It’s always refers to a mold that is stacked with a series of mold parting faces or mold split lines. Without increasing the machine platen size or tonnage, you can double the amount of cavities to enlarge the output, which increases molding efficiency and reduces the overall cost. Stack molds with same cavities in each mold parting surface can produce double of same standard plastic parts, while stack molds with different cavities in each mold parting surface can also produce multi-component or family parts in one shot on one plastic injection molding machine.


1)Doubled output: instead of increasing the mold size by adding more cavities, stack molds maintain mold size and machine size by adding a second layer of cavities parallel to the first layer. All the fill, pack and cooling time remain the same and only the mold open and mold close time add slightly to the cycle time. 

2)Reduced part and production cost: The part price is determined by the machines hour rate, which is directly related to the machine clamp tonnage. A stack mold requires only about half the clamp tonnage than a single-face mold with same number of cavities.

3)Efficiency and Improved Automation: Stack molds can produce multi-component assemblies in one shot on one plastic injection machine using the same parameters.
