OEM Factory Custom High Precision CNC Machining Stainless Steel Aluminum Sheet Metal Stamping Parts

CNC Machining Capabilities

Our CNC machining operations utilize multi-axis milling and turning centers to produce high-tolerance components from solid bar stock, plate, or extrusions. This process is essential for parts requiring tight geometric tolerances, complex 3D contours, or precise threaded features. We routinely hold tolerances to ±0.05mm on standard features and ±0.01mm on critical dimensions, verified through in-process probing and post-machining inspection.

Common applications include precision shafts, valve bodies, mounting brackets, and connector housings. The process supports a wide range of metals, including aluminum alloys (6061, 7075), stainless steel (303, 304, 316L), brass, and titanium. For prototypes and low-to-medium volume runs, CNC machining provides flexibility without the upfront cost of hard tooling.

Sheet Metal Stamping Capabilities

For high-volume production of thin-walled components, our sheet metal stamping lines offer unmatched efficiency. Utilizing progressive and transfer dies, we can produce complex geometries at rates exceeding hundreds of parts per minute. Stamping is ideal for enclosures, chassis, contact springs, and structural brackets where consistent cross-sections and high repeatability are required.

Our press capacity ranges from light-tonnage presses for delicate electronics components to heavy-duty hydraulic presses for deep-drawn parts. Material thickness capabilities span from 0.1mm foil to 12mm plate, depending on the material and forming complexity. We work extensively with cold-rolled steel, galvanized steel, aluminum, and copper alloys.

Integrated Manufacturing and Assembly

The true value of sourcing both processes from one facility lies in the seamless integration. Parts that require both stamped and machined features can be manufactured with coordinated datums, eliminating cumulative tolerance stack-up. We also provide secondary operations including MIG, TIG, and resistance welding, as well as mechanical assembly. This allows us to deliver complete sub-assemblies rather than loose components, reducing your incoming inspection and assembly labor.

Surface Treatment and Finishing

Raw metal parts rarely ship without surface treatment. We manage the entire finishing process in-house or through vetted partners to maintain quality control. Standard treatments include:

Anodizing (Type II and Type III) for aluminum components, providing corrosion resistance and surface hardness.

Zinc, Nickel, and Chrome Plating for steel parts, with options for clear or yellow chromate conversion coatings.

Powder Coating for durable, uniform finishes on larger assemblies and enclosures.

Passivation for stainless steel to restore the natural oxide layer and maximize corrosion resistance.

Bead Blasting and Brushing for aesthetic surface textures and matte finishes.

All surface treatments are performed to industry-standard specifications, with salt spray testing available to validate coating performance.
