Where Manufacturing Meets Service
We specialize in customized metal component manufacturing, covering a wide range of material processing such as investment casting, casting, bar stock, aluminum extrusion, as well as CNC precision machining, cold forging, hot forging, heat treatment, gear hobbing, broaching, welding, surface treatment, and final assembly.
With years of process integration experience and in-house equipment, we manage the entire production chain—from raw materials, cutting, forming, machining, and surface treatment to assembly and final inspection. Every step is controlled to make sure products meet international standards and customer requirements.
From prototyping, small-batch production, or mass manufacturing, we provide the process combination to each industry’s needs. Our solutions are widely applied in electric vehicles, automotive parts, agricultural machinery, drones, fitness equipment, pneumatic tools, and specialized product development.
By choosing us, you can consolidate multiple processes in one place, streamline your supply chain, reduce costs, and accelerate time-to-market—all with consistent quality and reliable delivery to enhance your brand competitiveness.
Raw Materials
We provide a wide range of raw material integration services, including bar stock, aluminum, copper, tubing, investment casting, aluminum die casting, hot forging, cold forging, aluminum extrusion, stamping, laser cutting, cold drawing, plastic injection molding, and more.
CNC Processing
Combining our in-house production capabilities and equipment —including lathes, milling machines, 4.5-axis milling machines, and both Swiss-type and conventional CNC lathes—we deliver the most efficient manufacturing solutions for our customers.
Casting
Casting is widely used in metal manufacturing, and we provide both small- and large-batch casting processes, including investment casting and sand casting.
Hot Forging
Hot forging is widely used for automotive chassis parts, drivetrain components, shafts, and high-pressure valve parts, and is one of the common processes we provide for our automotive industry clients.
Powder Metallurgy
Powder metallurgy allows high-volume production of precise and complex shapes with excellent material efficiency. We often apply this process to transmission parts, gears, bushings, and oil-impregnated bearings.
Die Casting
We provide die casting, which injects molten metal into molds under high pressure. It is ideal for high-volume, thin-walled, complex, and precise parts, with long mold life, low machining needs, and excellent material efficiency.
Gearing
We work with a complete network of gear-processing partners, offering processes such as hobbing, shaping, and broaching. Based on your drawings and technical requirements, we provide the most suitable production solution.
