Lightweight Insert Molding 600K - 1.2M Cycles Molds For Plastic And Metal

Insert injection molding involves pre-placing metal parts, threaded parts, ceramic parts, or electronic components within the mold cavity. Molten plastic is then applied to the insert surface via injection molding, resulting in a single-step molding process. This technology ensures both lightweight and multifunctional products, eliminating subsequent assembly steps and significantly improving production efficiency.

1. Mold Design: Determine the fixing method and flow channel structure based on the insert type and functional requirements.
2. CAD/CAE Analysis: Simulate plastic flow and wrapping effects to optimize insert force and positioning.
3. Precision Machining: Use CNC and EDM to create insert slots and cavities.
4. Mold Assembly: Install cooling water circuits and specialized insert positioning devices.
5. Mold Trial Verification: Test the bond strength, dimensional accuracy, and surface finish between the plastic and the insert.
