Sheet metal fabrication is a metal processing technology, mainly through the metal plate cutting, bending, welding and other processing technologies, to manufacture various shapes of metal products.

The commonly used material is a metal plate, and the finished products mainly include shells, bases, brackets, stampings, etc., which are widely used in the fields of furniture, electronics, communication, construction, automobile, machinery, chemical industry, and so on.

Commonly used surface treatment processes include brushing, powder coating, bead blasting, anodizing, silkscreen and laser marking, etc., which can cover most of the surface treatment needs of sheet metal parts.

Supported Sheet Metal Types

Currently supported metal sheet types and thicknesses are listed below; other specifications are not supported for now.

Supported Surface Treatment Processes

The surface treatment processes currently supported include brushing, powder coating, bead blasting, anodizing, silkscreen, laser marking, and more.

Standard: Parts are machined and deburred with no additional surface finish. Visible machining marks, light surface scratches.

Brushing: Parts are brushed using an abrasive tool to create a pattern of fine parallel lines on the material surface, producing a unique aesthetic effect.

Powder coating: Electrostatic dry powder application cured under heat. Eco-friendly, durable finish with superior corrosion resistance for metal parts.

Bead blasting: Parts are bead blasted with glass beads which results in smooth, matte appearance and reduced machining marks.

Anodizing: Anodizing creates a corrosion-resistant, uniform, matte or glossy finish. Parts can be anodized in different colors—black, red, and gold are most common.

Silkscreen: A part marking technique that uses a fine mesh screen to apply ink onto a surface, to print the desired text or image onto the substrate.

Laser marking: Laser marking uses a laser beam to create permanent marks or designs on the surface of a material, typically resulting in high precision and resolution.

Hardcoat anodizing: A type of anodizing that produces a thicker and harder coating on the surface, resulting in increased wear resistance and durability.

Conductive anodizing: An anodizing process that creates a conductive oxide layer on the surface, typically used for EMI/RFI shielding or electrical grounding applications.

Current Processing Capabilities

We currently have processing technologies such as laser cutting, bending, Tapping and countersinking, which can meet the processing needs of most sheet metal workpieces, and punch pressing/stamping technology will also be launched in the near future.

Laser cutting: There are two sets of 6000W laser cutting equipment, which have completed the debugging of cutting parameters for 0.5~6.0mm thickness plates.

Sheet metal bending: There is one TRUMPF bending machine (high precision, high cost); one pure electric bending machine (fast, stable); one electro-hydraulic bending machine (cheap, high pressure).

We have commonly used upper and lower die bending dies, straight tool, curved tool, step-difference dies, full arc dies within R3-R20, etc., which can meet various bending needs.

Tapping and countersinking: There are several bench-top drilling machines and hand drills available, which are highly efficient and flexible in processing. In the future, we will also introduce punch countersinking and develop automatic countersinking tool paths to solve the problem of lack of consistency in manual countersinking and difficulty in ensuring quality.

Riveting and sprouting: There are two riveting and sprouting equipment and several sets of riveting and sprouting dies. They can meet the riveting and sprouting processing needs of riveting nuts, studs and screws with various specifications of M2.5-M10.

Welding and polishing: There are two argon arc welding equipment, three laser welding equipment, and two two-way welding equipment, which are mainly used for the production of sample parts and small batch parts. They are highly flexible and meet various welding needs; Recently, two automatic welding equipment have been introduced, which are mainly used for the production of batch parts. The welding continuity and stability have been greatly improved.

Punch pressing/stamping: a new CNC punching machine, has been equipped with louvers, convex package, countersunk holes, rolling rib and other conventional molds and several sets of special molds (not formally used on-line), punching accuracy of ± 0.1, can be processed up to a maximum plate thickness of 6mm!
