Integrated Metal & Plastic Insert Injection Molding
Enhance structural strength, improve connection stability and simplify assembly work
Overview：Specialized in precision insert molding manufacturing, we encapsulate varied metal and functional inserts within engineered plastics. This optimized manufacturing technique simplifies product assembly, while upgrading parts’ mechanical performance and functional attributes. We support customized development and volume manufacturing for high-precision industrial, electrical and automotive structural components.
Metal Insert Encapsulation: Embed threaded studs, brass pins, stainless fasteners and conductive components into plastic in one molding cycle.
Multi-Material Overmolding: Combine rigid engineering plastics with metal or hard plastic inserts to achieve integrated composite structures.
Structural Reinforcement: Strengthen weak plastic stress points to prevent thread slipping and improve overall load-bearing capacity.
Functional Customization: Manufacture electrically conductive, heat-dissipating and positioning structural parts for specialized scenarios.
Precision Mold Development: Custom fixture-based molds designed to solve insert offsetting and floating issues for high-precision parts.
Full-cycle Manufacturing: Support design optimization, sample validation, small-batch trials and stable mass production for industrial-grade components.
Insert Molding
Embed metal or functional inserts inside, wrap plastic outside
Core function: Strengthen structure, thread assembly, load bearing and electric conduction
Application: Force-bearing parts, screw assembly and electrically connected products
Overmolding
No internal metal parts, secondary wrapping with different soft and hard plastic
Core function: Anti-slip grip, waterproof sealing, shock absorption and appearance upgrading
Application: Handles, housings, daily anti-slip goods and appearance functional products
Custom fixtures and optimized mold structure ensure accurate insert alignment, minimizing displacement and delivering consistent high-precision parts.
Professional surface treatment for inserts enhances adhesion between metal and plastic, preventing separation under long-term use.
Equipped with high-end CNC and EDM machines, we build durable molds stable for long-run mass production.
Support prototype sampling, small trial orders and large-volume manufacturing with reliable lead time and competitive cost.
Equipped with high-end CNC and EDM machines, we build durable molds stable for long-run mass production.
Experienced in pairing various engineering plastics with brass, stainless steel, aluminum and other insert materials for diverse project demands.
We support integrated molding of all special-shaped, bent, stamped and non-standard metal inserts.
Built-in precise limit structure inside molds fixes inserts firmly without position deviation.
Sample lead time: 3-7 days, mold development: 12-20 days, fast arrangement for mass orders.
Mold cost is slightly higher at first, but it saves plenty of labor time with higher comprehensive cost performance for long-term mass production.
