Overmolding is an injection molding process that creates a new item by injecting multiple doses of thermoplastic one after the other. A thermoplastic injection into a tool or cavity produces a substrate prior to the injection of an Overmolding material into a machine. The thermoplastic layers combine as they cool to form a solid and extraordinarily durable final product. The binding between substrates will differ depending on the properties of the suitable Overmolding material.
Overmolding has considerably enhanced the performance of several goods for today's market. In addition to significantly lowering noise and vibration, overmoulding has other benefits including soft touch and sealing. The ability of two plastics to securely bind with one another outperforms that of several glues.
At CN Mould & Plastic Limited, Overmolding is a slightly different process than insert molding in that it involves mixing two or more plastic or elastomer components to produce a single product. Plastic Overmolding can help reduce manufacturing timelines because the second piece is molded directly onto the first portion rather than having to completely create the two pieces separately and then combine them. Overmolding is a difficult process, but CN Mould & Plastic Limited can keep even the strictest tolerances.
Whether you want to create a prototype or scale up for a large production run, the material you choose for your manufactured parts is a crucial consideration. The needed degrees of accuracy, the size tolerance, and possibilities for post-processing like plating, painting, texturing, and polishing must all be taken into consideration. There are several choices for Overmolding materials, including but not limited to:
Common materials
Polyethylene (PE)
Polypropylene (PP)
Polycarbonate (PC)
Acrylonitrile Butadiene Styrene (ABS)
Supported materials
PEEK
Nylon (PA 6, PA66, PA 12)
Thermoplastic Elastomer (TPE)
Thermoplastic Vulcanizate (TPV)
Other
Flame retardants
Plasticizers
Colorants
Glass fibers
