What’s New

Ming-Li Precision provides both bearing insert molding and bearing overmolding solutions, in which the bearing is positioned directly inside the mold and integrated with the plastic component during the injection molding process.

When international customers search for an insert molding manufacturer in Taiwan or an overmolding manufacturer in Taiwan, one of their greatest concerns is whether they are communicating directly with the actual factory. Many companies found online describe themselves as manufacturers, but some are actually trading companies, sourcing agents, mold brokers, engineering consultancies, project coordinators, or collaborative design companies. They may receive the customer’s drawings and requirements, then subcontract the mold design, tooling, injection molding, automation, inspection, and production to several unrelated factories.

Ming-Li Precision recently supported a customer in the development and manufacturing of a new automotive connector with an integrated indicator light function. This component is not a simple plastic housing, but a functional connector module combining metal pin positioning, transparent light-transmission features, precision molding, overmolding, and final indicator marking. The product demonstrates Ming-Li’s capability in developing complex automotive plastic components that require both mechanical precision and functional integration.

At Ming-Li Precision Steel Molds Co., Ltd., we specialize in advanced insert molding and overmolding technology to integrate powder metallurgy inserts, precision stamping inserts, and electrical wires into highly integrated microwave switch assemblies using LCP (Liquid Crystal Polymer).

How Ming-Li Precision Integrates ABS + TPV + FPC (Flexible Printed Circuit) for High-Reliability Electronic Products As electronic products continue to evolve toward miniaturization, lightweight structures, smart sensing, and higher reliability, manufacturers are increasingly integrating FPC (Flexible Printed Circuit) into product designs to improve flexibility, functionality, and assembly efficiency.

In 2026, manufacturers are under growing pressure to reduce assembly costs, improve product durability, and create more compact, lightweight, and functional plastic components. As a result, Over-Molding and Insert Molding have become important technologies for product developers looking for stronger, smarter, and more efficient manufacturing solutions.
