Introduction to Insert Molding (Metal & Plastic Inserts)
Insert molding is a manufacturing process that combines two different materials – typically metal and plastic – to produce a single, integrated component. In this process, pre – formed metal inserts are placed into a mold cavity, and then molten plastic is injected around them. This results in a strong bond between the metal and the plastic, creating a part with enhanced mechanical properties, such as increased strength, improved electrical conductivity, and better dimensional stability. Insert molding is widely used in various industries, including automotive, electronics, medical, and consumer goods, due to its ability to reduce assembly steps, improve product quality, and lower production costs.
