The material and structure of the insert molding need to be selected according to the functional requirements of the product, and different types of inserts correspond to different application scenarios:
Metal insert molding: Primarily made of copper, steel, aluminum, and other materials, common forms include threaded studs, nuts, and shaft sleeves. They are used to enhance the connection strength and wear resistance of products. Typical applications include fixing nuts for home appliance casings and installation buckles for automotive interiors.
Ceramic/glass insert molding: Characterized by high temperature resistance and strong insulation properties, they are commonly used for insulating packaging of electronic components and structural parts in high-temperature environments.
Plastic insert molding: Made of reinforced or specialty plastics, they are used to achieve functional complementarity between different plastic materials, such as composite seals where a hard plastic insert is combined with a soft plastic body.
Other insert molding: including functional inserts such as magnetic materials, optical fibers, and sensors, which are used to impart special functions such as magnetic control and signal transmission to products, such as magnetic positioning inserts in smart devices.
