Ming-Li Precision Delivers High-Performance Power Module Housing for Taiwan EMS Leader, Supporting a Major U.S. AI Technology Company

Taichung, Taiwan – Ming-Li Precision Steel Molds Co., Ltd., a leading Taiwan-based specialist in ultra-precision mold manufacturing and injection molding solutions, proudly announces the successful mass production of high-performance Power Module Housing assemblies for a leading Taiwanese electronics manufacturing services (EMS) provider. The end application supports advanced power systems deployed by a major U.S.-based AI technology company.

This project highlights Ming-Li Precision’s ability to deliver high-reliability, high-precision plastic and insert-molded solutions for next-generation AI infrastructure, where performance, thermal stability, and dimensional accuracy are mission-critical.

Precision Manufacturing for AI-Driven Power Systems

With the rapid expansion of AI data centers and high-performance computing (HPC) systems, power modules must meet increasingly stringent requirements for:

Thermal stability under high current loads
Tight dimensional tolerances for DBC and busbar alignment
Electrical insulation integrity
Long-term mechanical reliability
High-volume production consistency

Ming-Li Precision’s Power Module Housing solution was engineered and manufactured to support demanding industrial and AI-grade environments, ensuring stable mechanical positioning and electrical insulation within the power module assembly.
