- Key control points of core technology
Positioning accuracy: The positioning error of the insert must be controlled at the micrometer level, otherwise it will lead to poor assembly or failure of bonding of the product. Common positioning methods include mechanical positioning, vacuum adsorption positioning, etc.
Material compatibility: It is necessary to match the thermal expansion coefficients of the plastic and the insert to avoid cracking due to shrinkage differences during the cooling process. For example, aluminum alloy materials with an expansion coefficient close to that of plastic can be selected for metal inserts.
Injection molding parameter optimization: The temperature of the molten plastic needs to be adjusted according to the heat resistance of the insert. The injection speed should not be too fast to prevent insert displacement or plastic decomposition.
- Core technological advantages
Integrated molding: No subsequent assembly processes are required, reducing production steps, enhancing production efficiency, and minimizing assembly errors.
Functional integration: By combining the flexibility of plastic molding with the special properties of inserts, functional combinations such as “lightweight of plastic + robustness of metal” and “insulation of plastic + high temperature resistance of ceramic” can be achieved.
Lightweight structure: Compared to all-metal products, insert molding can reduce material usage while ensuring strength, enabling lightweight design of products.
