Example of sheet metal fabrication


manufacturing materials Materials

The sheet metal materials we offer include aluminium, brass, stainless steel and copper, each of which has its own characteristics that determine their use in different areas of application

Aluminum

Aluminum is a lightweight, silver-white metal with a low density, which makes it lightweight and easy to machine.

Stainless Steel

Stainless steel is an alloy steel containing at least 10.5% chromium by mass. High corrosion resistance, durability and strength. It can be made in different shapes and sizes through various processes such as casting, forging and welding.

Brass

Brass has desirable properties for a number of applications. It is low friction, has excellent electrical conductivity and has a golden (brass) appearance.

Copper

Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.

Copper Passivation

Sheet Metal Fabrication Finishes

Sheet Metal parts often require surface finishes to enhance their appearance, functionality, and durability. The type of surface finish applied depends on the end application of the part and the desired characteristics.

Anodizing

Durable and corrosion-resistant, anodizing forms a protective coating on the surface of aluminum and titanium components, increasing their corrosion and wear resistance and can be colored for a variety of decorative effects.

Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

Bead Blasting

Powder Coating

Powder coating is a surface treatment process that involves applying dry powder to materials such as metal or plastic, then heating to fuse the powder particles and create a smooth, durable coating. The process can be used to apply a variety of colors, textures and finishes to the surface of the material.

Powder Coating

Electroplating

The electroplating process involves several steps, including cleaning and preparing the substrate surface, coating it with a conductive material, immersing the substrate in an electrolyte solution, and applying an electrical current to deposit metal ions onto the substrate surface. The resulting metal layer can be polished, textured or colored to achieve a variety of finishes.

Polishing

Involves smoothing and shining the surface of a material such as metal, plastic or glass to improve its appearance, texture and reflectivity. The process involves the use of abrasive materials, such as polishing compounds or diamond grit, to remove small imperfections and scratches from the surface of the material, resulting in a smooth and shiny finish.

Polishing

Brushing

Create a line pattern on the surface of a material such as metal with an abrasive belt or abrasive pad. This process is often used to create a decorative finish on metal surfaces or to remove small imperfections and scratches.

Definition of sheet metal fabrication

Sheet metal fabrication, also known as sheet metal fabrication, is a comprehensive cold working process involving thin metal sheets.

It includes steps such as shearing, punching, bending, welding, riveting, mould forming and surface treatment.

The distinguishing feature of sheet metal processing is the consistent thickness of the same part, which makes it widely used in the fields of electronics and electrical appliances, communications, automotive industry, medical devices, etc.

Main Process Flow of Sheet Metal Fabrication

  1. Design: draw detailed drawings and process flow according to product requirements.
  2. Material Preparation: Select suitable metal sheets and laser cut them according to the size requirements.
  3. Cutting: Use shears and laser cutting machine equipment to cut the metal sheet into the required shape.
  4. Bending: Bend the sheet metal into the required shape for the design by bending machine.
  5. Stamping: The sheet metal is impacted using the made moulds and punching machines to form specific shapes such as holes, depressions or bumps as required.
  6. Welding: Multiple sheet metal parts are combined and fixed, and welded together using a welding machine.
  7. Surface treatment: including polishing, galvanising, powder coating, sandblasting anodising colouring, etc. to improve the appearance and corrosion resistance of the product.
  8. Assembly: Combine individual parts to form the final product, using welding, bolting, etc. to secure it.
What are the three 3 types of sheet metal fabrication?

Shearing: A processing method that utilises mechanical force to cut metal materials to a desired size. It consists of two types of shearing: flat shearing and mitre shearing, and is suitable for producing sheet metal with straight edges.
Stamping: through the mould on the metal plate pressure, so that it produces plastic deformation, to obtain the desired shape of the processing method. It includes a variety of operations such as bending, stretching, punching, etc., and is suitable for the production of complex shaped metal parts.
Bending: A processing method in which a sheet of metal is bent to a certain angle along a predetermined line. Completed by hand or mechanically, it is suitable for producing metal parts with a certain bending angle.

What is the difference between sheet metal fabrication and machining?

There are significant differences between machining and sheet metal working in terms of the form of the material from which the process is started.
Machining usually takes a solid block of metal as its raw material, and gradually removes the excess material by cutting, grinding, etc., to form the desired shape and size of the part.
Sheet metal processing starts with a sheet or coil of metal and uses bending, folding and other deformation processes to plastically deform the material to obtain the desired product contour.
This difference results in the two processes differing in terms of the processing equipment, the process flow, and the area of application of the final product.
