A Real Factory, Not a Trading Company

Dongguan Shengsi Metal Products Co., Ltd. was founded in June 2011. For fifteen years we have done one thing: precision metal fabrication — stamping, sheet metal, and coating, from drawing to finished product.

We design, develop and manufacture metal parts with strong in-house production capacity and a complete after-sales system. Because every core process — laser, bending, welding, powder coating, and final assembly — runs on our own machines, we control both lead time and quality.

What We Make

Four product lines, all built to your drawings or samples — from coin-sized stamped parts to complete assembled cabinets.

⚡

EV Charging & Energy Storage

Charging pile enclosures and energy storage cabinet bodies — structure and finish in one place, co-developed with new-energy infrastructure customers.

🔌

Power Supply Enclosures

Power supply housings and heat-dissipation stampings — vent hole arrays, air-duct bends and mounting holes formed in one stroke for strength plus cooling.

🖥️

Cabinets & Self-Service Terminals

Equipment cabinets, medical carts, ATM series, government and banking self-service terminals — welded, coated and fully assembled in our dedicated final assembly workshop.
