Overmolding is an important processing method in modern manufacturing and is widely used in electronics, automobiles, medical and other industries. Although the early manufacturing process of the plastic injection mold has been completed, there are still many potential problems in the plastic overmolding process, which may lead to incomplete or substandard injection molded parts. In this article, KRMOLD will discuss in detail the most common problems and solutions in the overmolding process.

One injection molding technique often employed in contemporary manufacture is overmolding. This method allows one or more materials to be sprayed on a surface to create integrated components having several qualities. Beyond just increasing a product's usefulness, plastic overmolding elevates its aesthetic appeal and user experience. The material selection, benefits, and uses of overmolding in several sectors will be covered in depth in this essay.

Overmolding refers to the fastest, multi-step process of molding a layer of polymer over a substrate part using TPU injection molding methods. It usually represents the mechanical entanglement of polymer molecules. Usually, it is an injection molding process. The substrate part (the toughest part) is usually made of plastic and made by the plastic overmolding process. From toothbrush manufacturing to vibration reduction, and critical internal durable and elastic parts in automobiles and aerospace, the overmolding of small-size parts has received great attention. The process is carried out by chemical or physical interlocking.
