What Does the Sheet Metal Fabrication Process Look Like?

Sheet metal manufacturing involves a series of processes that transform flat sheets of metal into finished parts. Here is a general overview of how sheet metal manufacturing works:

Design and Engineering

The process begins with the design of the desired part or component. Product designers create detailed drawings or 3D models that specify dimensions and tolerances. Design software such as CAD (Computer-Aided Design) is commonly used in this stage and 3D images can be converted and exported to 2D formats for manufacturing. 

Material Selection

Based on the design requirements, the appropriate type and thickness of sheet metal are selected. Common materials used in sheet metal manufacturing include steel, aluminum, stainless steel, copper, and brass. Factors such as strength, durability, weight, and cost are taken into consideration during material selection.

Sheet Metal Cutting 

The selected sheet metal is cut into the desired shape and size. Several cutting methods can be employed, including shearing, laser cutting, and waterjet cutting.

Hole Operations

Hardware insertion, tapping and countersinking are all options during production. Following spacing specifications and taking into account additional operations (bending) can make or break a design that includes hole operations. 

Forming and Bending 

The cut sheet metal is then shaped and bent into the desired form. This is typically achieved using specialized machines such as press brakes or rollers. The sheet metal is clamped between a punch and a die, and pressure is applied to deform it into the desired shape. This process creates features like curves, angles, flanges, or bends.

Joining 

Depending on the design and requirements of the part, various joining methods are used to connect different sheet metal parts. Common joining techniques include welding, riveting, or adhesive bonding. 

Finishing OperationsAfter forming and joining, the fabricated sheet metal part may undergo additional finishing operations to improve its appearance and surface quality. These operations can include grinding, sanding, polishing, deburring (removing sharp edges), plating, anodizing, or applying paint or powder coating.

Quality Control 

Throughout the manufacturing process, quality control measures are used to ensure that the produced parts meet the required specifications. This can involve inspections, dimensional checks, and testing for strength or other performance characteristics.

Sheet Metal Cutting: How is Sheet Metal Cut? 6 Techniques 

Sheet metal cutting techniques are divided into two categories: cutting with shear, and cutting without shear. Cutting with shear includes processes where the material is cut by a shearing force that overcomes the material’s ultimate shear strength. The material is held while a punch presses down and shears the material. 

On the other hand, cutting without shear includes processes that create the cut by the use of extreme heat, or abrasive blasting, thus, avoiding cutting with a shear force pressing onto the material. Below are some examples of each type of cutting.Metal Cutting Without Shear

Laser Cutting

Laser cutting uses a focused laser beam to cut through various materials. It works by directing a high-energy laser beam onto the material, causing rapid localized heating and melting, resulting in a clean and precise cut.

Waterjet Cutting

Waterjet cutting uses a high-pressure jet of water mixed with abrasive particles to cut through various materials. The waterjet is directed through a small nozzle at extremely high velocity, resulting in erosion and separation of the material.

Plasma Cutting

Plasma cutting uses a high-velocity jet of ionized gas (plasma) to cut through electrically conductive materials. The plasma is created by passing an electric current through a gas, which elevates its temperature and ionizes the gas particles. The energized plasma is directed through a nozzle, creating a focused cutting stream that melts and blows away the metal, resulting in precise and fast cuts.

Metal cutting with shear

Shearing 

Shearing involves cutting a straight line through the material with the use of a press or die. It separates the work part into two separate pieces by the application of a shearing force. 

Blanking and Punching

Blanking involves cutting out a flat shape or profile from a larger sheet, typically using a die and a punch, leaving behind the desired part. Punching, on the other hand, involves creating holes or perforations in the material using a punch and die combination, allowing for the creation of openings, slots, or patterns in the sheet.

Sawing

Sawing is a cutting process that utilizes a saw or a similar cutting tool to divide materials into desired shapes or sizes. It involves the use of a serrated blade or a rotating abrasive wheel that removes material by creating a cutting action.

SendCutSend uses cutting techniques that are without shear. Therefore, we offer laser cutting, waterjet cutting, and plasma cutting for your sheet metal cutting needs. These techniques are very precise and fast, thus creating high-quality sheet metal parts with fast turnaround times. 

Sheet Metal Forming Techniques

Bending involves deforming the sheet metal along a straight line to create angles, curves, or folds. This can be achieved using press brakes or other bending machines that apply force to the metal, causing it to bend.

Roll Forming

Roll forming is a continuous bending process used to create long, uniform profiles or shapes. The sheet metal is passed through a series of rollers, which gradually bend it into the desired form. Roll forming is often used for creating things like channels and tubes. 

Punching

Punching is a process that involves creating holes, slots, or other geometric shapes in a sheet of metal. It is achieved by using a punch and die set, where the punch applies force to the sheet metal, and the die provides support and guides the material.

SendCutSend’s forming capabilities are very capable of creating complex shapes and structures from flat metal sheets.

Sheet Metal Joining Techniques 

There are several common techniques for joining sheet metal components together.

Welding

Welding is a process that joins two or more pieces of metal by melting and fusing them together. In sheet metal, common welding methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and spot welding. Welding provides strong and durable connections, particularly for structural applications.

Riveting

Riveting involves joining two or more sheets of metal using rivets. A rivet is inserted through pre-drilled holes in the sheets, and the protruding end is deformed to create a permanent connection. Riveting is often used when high strength and structural integrity are required.

Mechanical Fasteners

Mechanical fasteners such as screws, bolts, nuts, and self-clinching fasteners can be used to join sheet metal components together. They provide a secure connection and are often used in applications where disassembly or adjustable connections are required.

Soldering 

Soldering is a joining technique that uses a low-temperature metal alloy called solder to bond two or more metal surfaces together. It is commonly used for electronics where a low-heat method is needed.

The choice of joining technique depends on factors such as the strength requirements, material types, production volume, and specific application needs. Although SendCutSend is not currently offering services related specifically to joining parts, our hardware installation service has been designed to create parts that can be then easily joined together. 

Surface Finishes For Sheet Metal Products

Different sheet metal surface finishes are applied to provide various properties and aesthetics for the finished sheet metal product. Some of these include mill, painted, powder coated, galvanized, brushed and anodized finishes. 

Mill finish refers to the untreated surface of sheet metal with visible machining marks. Painted finishes involve applying a layer of paint or coating for custom colors, enhanced appearance, and corrosion resistance. Powder coating offers a durable, uniform finish with excellent protection against corrosion, scratches, and UV damage. Galvanized finishes use a protective zinc coating to resist corrosion in outdoor or corrosive environments. Anodized finishes create an oxide layer on aluminum for improved corrosion resistance and decorative options. Brushed finishes create a textured or satin-like appearance through abrasive brushing. 

Other finishes include polished, plated, or laminated surfaces, each offering unique properties and appearance for specific sheet metal applications. They can all improve the final product’s appearance and durability, but the choice of finish ultimately depends on factors such as material, functionality, durability requirements, aesthetic requirements, and environmental conditions.
