How to Fabricate Sheet Metal ?

Generally, we can shap sheet metal by cutting or forming. Since there are various ways of cutting and forming, we utilise many specific tooling, which may drive up costs. If you know more about fabrication procedures, you can design your sheet metal parts more efficiently.

Sheet metal typically comes in thicknesses ranging from 0.006 to 0.25 inches (0.015 to 0.635 centimetres). The fabrication begins with a flat sheet of metal. Your design files (3D files) show how to cut, form, and finish the sheet metal parts. We can cut and form the material, and then join them together.  We can make it into angel iron by bending, laser cutting, and bending the edges to make enclosure panels.

Precision Sheet Metal Fabrication

An experienced engineer knows better about the character of materials, stretch calculations, and grain direction to make sheet metal parts more precise. Compared with “non-precision” parts, precision sheet metal fabrication needs more techniques and better equipment.

Toolings for Stamping & Roll Forming
Stamping Tooling
Stamping Tooling

For some sheet metal parts, we need to make Stamping Tooling and Roll Forming Tooling to manufacture them. It will take us a few weeks and cost thousands of dollars to make these toolings. Therefore it is suitable for manufacturing large quantities of parts.

Commonly used sheet metal tooling has five categories: punching tooling, bending tooling, drawing tooling, forming tooling and compression tooling. Read More about Sheet Metal Stamping Toolings

Cutting Sheet Metal

Compare of cutting types

Cutting Types Tolerances Cost Mt. Thickness
Laser cutting 0.05 mm (0.002 in) $ 0.30-1.02 mm (0.12-0.4 in)
Plasma cutting 0.5 mm (0.02 in) $ 0.5-180 mm (0.02-7.01 in)
Water jet cutting 0.2 mm (0.008 in) $$ 10.16-50.8 mm (0.4-2 in)

Forming sheet metal

Sheet Metal Forming

During the fabrication process, we usually punch and cut the sheet metal first in different ways. And then it is followed by forming processes to make a nearly finished and realised product. Forming also adds strength and stiffness to an assembly.

Sheet Metal Stamping

Stamping is a forming method for a workpiece of the desired shape and size by applying external force to a press and a die to cause plastic deformation or separation. The characteristics are high efficiency. And the stability is strong, but the cost is high. We control the quality of parts with the mold and use it for mass production.

Sheet Metal Joining

There are various approaches to joining sheet metal parts suited to different applications. Common approaches include fastenings, welding, and soldering

Materials for Sheet Metal Parts
Sheet Metal Materials

Sheet metal parts use a wide range of materials. You should choose an appropriate material based on your needs for strength, hardness, flexibility, and corrosion resistance. However, the materials most suitable for sheet metal fabrication are those which you can manipulate and do not lose their physical properties. Aluminum and steel are examples of such materials.

Additionally, as sheet metal fabrication projects often include bending, machining, or welding, there are a number of factors to pay particular attention to when selecting an appropriate material. These include:

  • Ductility (elongation at break)
  • Machinability
  • Weldability
  • Tensile strength
  • Corrosion resistance
  • Weight
  • Cost

Common Sheet Metal Materials

Material Elongation at break Machinability Weldability Corrosion res Tensile strength Cost
Aluminum 5052 7 – 27 % 195 – 290 MPa $
Aluminum 5754 10 – 15 % 160 – 200 MPa $
Stainless Steel 304 45 – 60 % 480 – 620 MPa $$
Stainless Steel 316L 30 – 50 % 480 – 620 MPa $$
Mild Steel 1018 17 – 27 % Poor 190 – 440 MPa $
Copper 110 15 – 50 % Poor Moderate to Poor 220 – 230 MPa $

Note: The aluminum series 5xxx is more suited to sheet metal fabrication than the aluminum series 6xxx. This is because aluminum series 5xxx is more ductile and tears less easily when bent.

Common Sheet Metal Finishes

The finishes available for sheet metal parts are similar to those of other metal fabrication processes. You can select the best finish based on your needs and the properties of the material you used.

We compare the most common finishes and how they are applicable to sheet metal below. For more general descriptions, information on roughness, color options, grit etc., and images of each of these finishes, check out this page on surface finishes.

Bead Blast
Anodized
Powder Coat
Polishing
Brushing
Gold Plating
Finish Type Description Pros Cons Price Increase Application
Bead Blast Shooting glass beads or other abrasives at the part at high speed.The part surface is left with a smooth, matte appearance
  • Removes tool marks and deburrs
  • Adds uniform matte or satin surface finish
  • Improve grip
Critical dimensions and surface roughness will be affected. $ Used mainly for visual purposes and to prepare surfaces for other coatings. Can be combined with anodizing.
Powder Coating Electrostatically applies a dry powder—typically a thermoplastic or thermoset polymer—to the metal surface.
  • Adds a decorative layer
  • Increase corrosion resistance
  • All metals are compatible.
  • Higher durability than paints
  • Internal surfaces are difficult to apply
  • Compared to anodizing, it is less dimensional control
$ $ $ It adds a decorative and protective layer to all metals. And, it can be combined with bead blasting.
Anodizing This is an electrochemical procedure for coating a substance, generally aluminium, with a stable oxide layer.It creates a corrosion-resistant and wear-resistant layer.
  • Adds the material a smooth almost matte texture
  • Durable & good looking
  • Can be applied easily to internal cavities and small parts
  • Wide range of colors available
  • Electrical conductor of poor quality.
  • In comparison to powder coating, it is more brittle
$ $ $ $ It can be used to improve corrosion resistance and aesthetic appeal on aluminium, titanium, zinc, and magnesium.
Chromate Conversion  Coating This process immerses parts in a chemical bath until a corrosion-resistant conductive coating has formed.
  • Corrosion Resistant
  • Paints adheres well, can act as primer
  • Increases durability
  • Only a few colours are available (yellow, gray, white)
  • Abrasion resistance is low
$ $ Best for functional parts, not for decorative use.
Brushing Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish.
  • Removes machine marks
  • Not corrosion resistant
  • Does not increase durability
$ Brushing is mostly used for aesthetic purposes.
Applications of Sheet Metal

There are dozens of sheet metal fabrication techniques available. For example, butting flat sheets, bending parts, drilling holes, adding slots, notching, etc. These techniques enable us to make complicated parts.

Furthermore, there is a wide range of materials that can be used to fabricate. With the ability to withstand high heat, thermal conduction, electrical, and corrosive environments, sheet metal can be suitable for a diverse number of applications.

Sheet metal products have the characteristics of light weight, high strength, electrical conductivity, low cost, and good mass production performance. For example, in computer cases, mobile phones, and MP3s, sheet metal is an essential component. Also used in the manufacture of medical devices, car and truck (van) bodies, aircraft fuselages and wings, medical tables, building roofs (architecture) and many other applications. In fact, sheet metal is used in practically every industry.

Advantages of Sheet Metal Fabrication

Quick

Lead times on custom sheet metal prototype are usually short. It has the same precision and speed that it can produce in production.

Flexibility

It can be easily customised and adjusted.If the manufactured prototype doesn’t work as planned, you can adjust it next time. It is flexible, versatile, cost-effective. This character make it a best way to produce custom part

Cost-effective

Precision sheet metal fabrication can handle both low and high-volume production. When parts approach high volumes, sheet metal becomes even cheaper with consistent highe quality.

Strength, Durable

Sheet metal is lightweight, but adding bends to it increases its stiffness in multiple axes, therefore increasing the structure’s strength. It can withstand high pressure. Sheet metal parts are durable and resistant to corrosion and scratches due to a variety of surface finishings.
