In-mold labeling (IML) is a cost-effective solution for displaying labels on products. Unlike adhesive labeling, IML is the process of inserting the label during the molding cycle, therefore reducing the production cycle time. Furthermore, the label is integrated into the final product, limiting its wear out.
Overmolding is the process of molding over a finished part. The robot proceeds to insert a component directly into the mold, to overmold a part. This process makes it possible to stiffen a structure, or even to mold a product composed of different materials (bi-material molding).
Unmolding is the process of removing a part from the mold. By robotizing this operation, the production line can benefit of a reduction in molding time. The robot’s end-of-arm tooling can also handle plastic gate removal, avoiding an additional operation.
Hot inserting is a technique of inserting a metal part inside a plastic part after injection molding. This application will be put forward in cases where the design of the mold does not allow overmolding. The process involves heating a metal component by induction, then embedding it in the plastic part.
