Stack mold is a type of mold used in injection molding to produce multiple parts per cycle. It is made up of two or more mold parting surfaces stacked one on top of the other, which allows for the creation of multiple cavities in each mold plate. The stack mold can produce two or more identical parts in a single shot, which increases production efficiency and reduces costs. There are a few challenges to using stack molds, such as increased complexity and maintenance requirements. Nevertheless, the benefits of stack molds make them a popular choice for high-volume production of plastic parts.

2K mold as a two-shot mold or dual-material mold, is a type of injection mold that is used to manufacture complex plastic parts made of two different materials. The 2K mold process involves using two different materials and two different injection molding machines to produce a single part.

Over-Molding: Advanced Multi-Material Manufacturing Solutions Over-mold, or over-molding, is a manufacturing process that involves the injection molding of one material over another material to create a finished product with multiple layers. The process involves molding a base material, such as plastic or metal, and then molding a second material over the base material to form a final product with two or more layers. Over-molding is a versatile manufacturing process that can be used to create products with multiple layers, colors, and properties. The process is widely used in various industries to create products that are durable, attractive, and functional.
