Quality Tool & Die/QTD Plastics

Insert Molding & Overmolding


Overmolding is a process where we mold one type of plastic on top of another to enhance features such as grip, vibration dampening, soft touch/ergonomics, and sealing.

Insert Molding

Insert molding allows us to mold plastic over a variety of different objects, including blades, rods, threaded inserts, and tubing – joining the two objects more securely than a secondary assembly operation.

Vertical Insert Molding

While we perform insert molding in both horizontal and vertical machines, vertical molding machines provide an inherent advantage as it allows for the insert to be loaded, held in a stable position throughout the molding cycle, and unloaded from the mold.
