Sheet metal fabrication

Custom Metal parts by Sheet metal service

Sheet metal fabrication is a manufacturing process that involves forming metal sheets into various shapes and components through a series of operations such as cutting, punching, bending, welding, assembling, and forming (e.g., automotive body panels). The metal material sheets used are typically thin and can be shaped through cold working processes without heating, including stainless steel, iron, aluminum, copper, and other metals.

Sheet metal Processes

product design
design and drawing

The first step in sheet metal processing is product design and drawing CAD files.

sheet metal laser Cutting

This production process is cutting a metal sheet by a high-power laser beam.

sheet metal Bending

Use dies to produce a U-shape/V-shape or channel shape along a straight axis in ductile materials.

sheet metal Welding

A process that involves the use of heat, pressure, or both, to join two or more pieces of sheet metal together. 

deburring

Removing or grinding the burrs or ridges of parts produced during the production process

sheet metal finishing

Improving the surface quality, appearance, and durability of sheet metal parts after formed or fabricated.

Surface finishing processes for sheet metal parts refer to the various techniques applied to the surface of the metal to improve its appearance, durability, corrosion resistance, or other functional properties. Here are some common surface finishing processes for sheet metal parts:

  1. Powder Coating:
    • A dry finishing process where a powdered pigment is electrostatically sprayed onto a metal surface and then baked to form a smooth, durable coating.
    • It is available in a wide range of colors and textures.
  2. Painting:
    • A liquid paint is applied to the metal surface using various methods like spraying, dipping, or brushing.
    • Primer, base coat, and clear coat layers may be applied to achieve desired aesthetics and durability.
  3. Anodizing:
    • Primarily used for aluminum alloys.
    • An electrochemical process that forms a protective oxide layer on the surface of the metal, increasing corrosion resistance and durability.
  4. Electrophoretic Coating (E-Coating):
    • An immersion process where the metal part is submerged in a paint bath and an electric current is applied to deposit a uniform coating on the metal surface.
    • Often used as a primer before powder coating or painting.
  5. Zinc Plating (Galvanizing):
    • A process that applies a thin zinc coating to the metal surface by electrolysis or hot dipping.
    • Increases corrosion resistance and durability.
  6. Chrome Plating:
    • A thin layer of chromium is applied to the metal surface using an electrolytic process.
    • Provides a shiny, reflective finish and corrosion resistance.
  7. Nickel Plating:
    • Nickel is electroplated onto the metal surface.
    • Provides corrosion resistance, hardness, and aesthetic appeal.
  8. Polishing:
    • Mechanical process that smooths the metal surface by removing imperfections and rough edges.
    • Can be done by hand or using machines with abrasive media.
  9. Sandblasting:
    • Uses a high-pressure stream of abrasive material to clean and etch the metal surface.
    • Creates a matte or textured finish.
  10. Laser Etching:
    • Uses a laser to remove material from the metal surface, creating a design, logo, or text.
    • Provides a permanent, high-resolution marking.
  11. PVD (Physical Vapor Deposition):
    • A process that deposits a thin layer of material on the metal surface by vaporizing it and condensing it onto the substrate.
    • Commonly used for decorative coatings and improved wear resistance.
  12. Brush Finishing:
    • Uses wire brushes or abrasive media to create a textured or satin finish.
