Principle of Hot Riveting (Hot Melt Riveting): A plastic stud or rivet is heated until it softens; a press head then extrudes and forms the rivet head, securing the plastic part and metal insert or plastic assembly into a single unit. This method is suitable for thin-walled housings and the assembly of multiple small parts. It differs from hot melt welding of tubular materials and is primarily used in the assembly of injection-molded products.
