Lightweight Insert Molding 600K - 1.2M Cycles Molds For Plastic And Metal
Insert injection molding involves pre-placing metal parts, threaded components, ceramic parts, or electronic elements within the mold cavity. Molten plastic is then injected to coat the insert surface, creating a single-step molding process. This technology ensures lightweight, multifunctional products while eliminating assembly steps and improving production efficiency.
- Mold Design: Determine fixing method and flow channel structure based on insert type and functional requirements
- CAD/CAE Analysis: Simulate plastic flow and wrapping effects to optimize insert force and positioning
- Precision Machining: Use CNC and EDM to create insert slots and cavities
- Mold Assembly: Install cooling water circuits and specialized insert positioning devices
- Mold Trial Verification: Test bond strength, dimensional accuracy, and surface finish
