ylipainemuovausta

Ylipainemuovaus, also known as overmolding, is a manufacturing process where a softer material is molded over a rigid substrate. This process is often used to improve the ergonomics, grip, or aesthetics of a product. For example, many tool handles, pen grips, and electronic device casings utilize overmolding to provide a more comfortable and secure hold. The process typically involves two stages: first, the rigid substrate, often made of plastic or metal, is molded or otherwise fabricated. Then, this substrate is placed into a second mold, and a molten thermoplastic elastomer (TPE) or rubber is injected around it. The two materials bond together, creating a single, integrated component. The choice of materials is crucial, as they must be compatible to ensure good adhesion. Overmolding can be performed using various molding techniques, including injection molding and compression molding. Its benefits include enhanced durability, improved user experience, and the ability to combine different material properties in a single part. It is a versatile technique employed across numerous industries, from consumer goods and automotive to medical devices and industrial equipment.
