Overview of Insert Molding and Its Process

Mold and molding is a very well known term in plastic industries. For simple understanding mold is a hollowed out block or rigid frame. A liquid or pliable materials like plastic, glass, ceramic materials etc are filled in order to strengthen the material in order to get the desired shape. When the liquid hardens and sets inside the mold and takes the exact shape for which it was formulated.

Undoubtedly, insert molding is an emerging term in the recent technological world. Insert molding is a highly efficient process by which various electrochemical parts, metal saplings and discrete parts are combined into single components through the injection of thermoplastic.

As per the concept, inserts can either be incorporated at the time of the molding process, or can be inserted as a post molding operation. When we choose the first the inserts can either be loaded by robot assistance or by the process operator. If the inserts are applied in the second way as a post moulding operation, they can usually be applied any time after the molding process. But in some cases, they are inserted as part of a series of post molding operations. Two basic methods i.e post moulded installation and moulded-in- installation are adopted for insert moulding.
