Riveting

Stamping

Bending shapes sheet metal along straight lines using press brakes for accurate angles and consistent dimensions, essential for aesthetics and functionality.

   ● Achieves accurate angles consistently.
   ● Quick setup, fast execution.
   ● Adapts to various materials.

Welding is a fundamental metal fabrication process used to join metal pieces securely. It involves melting the base metal and a filler material to form a strong joint. 

   ● Creates strong, durable joints.
   ● Quick, save material costs.
   ● Suitable for various materials.

Riveting is a reliable fastening technique that joins metal parts without welding. It involves inserting and deforming rivets to assemble complex structures where welding is impractical.

   ● Durable, reliable connections.
   ● Avoids thermal distortion.
   ● Avoids thermal distortion.
Stamping presses metal into dies to shape specific forms efficiently. It mass-produces uniform parts and is widely used in automotive industries for complex geometries.

   ● Rapid, large-scale production.
   ● Uniform parts every time.
   ● Manages intricate shapes easily.

Surface Finishing Options for Metal Sheets

Enhance the durability and aesthetic of your custom metal parts with our variety of surface finishing options. For finishes not listed on our quote page, simply select “Other” and specify your requirements for a customized solution.


Oil sprayOil spray

Makes a product with rich color, uniform coating, environmental protection. The surface of die castings needs to be cleaned, deoxidized and chemically pretreated.

Anodizing Anodizing-2

Anodizing increases corrosion resistance and wear properties, while allowing for color dyeing, ideal for aluminum parts.

PolishingPolishing-2

Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.

Sand BlastingSand Blasting

Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.

TumblingTumbling-1

Tumbling smooths and polishes small parts by friction and abrasion in a barrel, offering a consistent but slightly textured finish.

Laser CarvingLaser Carving

The physical degeneration of the melting and gasification of the processed material under laser irradiation achieves the processing purpose.

AlodineAlodine-1

Alodine coating provides corrosion protection and improves paint adhesion, mainly used on aluminum surfaces.

Heat TreatmentHeat Treatment-1

Heat treatment alters the mechanical properties of metal to increase its hardness, strength, or ductility.

Brushed FinishBrushed Finish

A brushed finish creates a unidirectional satin texture, reducing the visibility of marks and scratches on the surface.

Powder CoatingPowder Coating-1

Powder coating applies a thick, wear-resistant layer with excellent color and texture options, suitable for a variety of surfaces.

ElectroplatingElectroplating-1

Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.

Pad Printingpad printing

Printing picture or text on another object with the carrier improves the aesthetics of the product, and increases the added value and market competitiveness.
