How does Sheet Metal work?
The below-mentioned steps are involved in the sheet metal fabrication process：
Design and CAD Modeling
The sheet metal fabrication process starts with creating a 3D CAD model, which outlines the product’s size, material, and specifications. This detailed CAD model is a blueprint, ensuring the final part meets all design requirements.
Material Selection
Material selection, such as aluminum, steel, or titanium, is crucial for enhancing product performance and durability based on the required strength, weight, and resistance. This ensures the part meets application demands effectively.
Machining Process
After selecting the material, the metal sheet is cut using a laser, water jet, or shearing to ensure accuracy and maintain material homogeneity. The sheet is then bent using press brakes to achieve the required angles and curves, ensuring the part’s geometry matches the CAD design.
Assembly
During assembly, welding may be used to combine all elements into the final product, ensuring efficient performance, structural strength, and overall system integrity.
Finishing Options
Polishing or painting enhances the part’s appearance and provides rust protection, preventing corrosion and improving surface quality. Finishing must meet design requirements and ensure functionality.

Types of Sheet Metal Operations
- Laser cutting Metal
Laser cutting is a highly accurate and effective technique for cutting metal sheets, and it is ideal for most operations. For thicker materials, plasma cutting is faster but less precise. Laser cutting is preferred for its superior quality.
- Mechanical Cutting
Shearing, or die cutting, is a process that cuts sheet metal without heat, similar to using scissors. It’s ideal for straight cuts and effective for parts that don’t require complex shapes.
- Bending
At Prolean Tech, we use bending processes with press brakes to shape metal into various parts, from brackets to enclosures. This precise technique is crucial in automotive, aerospace, and manufacturing industries.
- Punching
Punching cuts holes in sheet metal using a punch tool, ideal for high production volumes. It is cost-effective for creating multiple perforations or designs but can be expensive for small runs due to the need for various tools.
- Slotting
Slotting, or slitting, forms slots or notches in sheet metal using specialized machines. It’s crucial for applications requiring precise slots or unique fittings and connectors.

Finishing Options For Sheet Metal Part
As the machined or deburring
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.

Technology Overview
Introduction
Are you looking to create actual parts and products from your 2D or 3D design? Then, sheet metal fabrication might be the best approach for you.
Sheet metal fabrication refers to the creation of the desired shape from steps of the manufacturing process. It involves various alternatives for each step, such as cutting, bending, joining, and surface finish. But, choosing the right type of process helps optimize the fabrication’s functionality and cost. ProLean makes it easy for you. We decide the best steps for your project based on your requirements.
What is Sheet Metal Fabrication?
Sheet metal fabrication is converting the metal sheet into the desired shape. The process involves more than one step while manipulating the sheet metal to form the body, such as cutting, bending, welding, surface treatment, and many more, depending upon the complexity of the required shape.
The fabrication of sheet metal begins with drawings (2D& 3D). However, before starting the actual fabrication, manufacturers develop a 3D such as a CAD file. The 3D of desire shape provides guidance on what actions should be made, which strategy is the most appropriate and practical, which manufacturing steps are needed, and many other things.
Advantages
• Sheet metal fabrication is the low-cost and effective approach for prototype development and large-scale production.
• The finished part or product made of sheet metal has a high strength-to-weight ratio.
• Sheet metal fabrication offers a wide range of material options to create the desired shape.
Fabrication Steps
The steps of sheet metal fabrication begin with preparing a complete blueprint of required parts. For example, it might be the paper drawing or CAD-3D containing all dimensions. Then, it requires identifying the manufacturing steps such as cutting, bending, welding, assembly, & surface treatment.
Cutting the sheet metal is the step where the actual fabrication starts. Cutting the sheet metal into pieces as the dimension in the drawing can be achieved with various approaches such as CNC cutting, Laser cutting, and Water-jet cutting. After the Cutting operations, the cutting pieces need to be joined to form the shape with Riveting & welding. Other processes, such as bending and turning, are involved if angular or complex shapes are required. If holes are present in the shape, punching or drilling operations are used to create them.
Assembly of components is done to produce the desired shape according to the design of parts or products. Last but not least, surface finishing procedures, including plating, deburring, powder coating, or painting, must be carried out.
Applications
