Introduction of Sheet Metal Fabrication

Sheet metal fabrication is a comprehensive manufacturing process that shapes and forms sheet metal into specific parts and components. This process includes a range of techniques and procedures for cutting, bending, punching, welding, and assembling sheet metal to produce the final product. It is widely utilized in sectors like automotive, aerospace, construction, and electronics, among others. The following are some principal elements and procedures in sheet metal fabrication:

Material Selection: Sheet metal can be made from a variety of materials, including steel, aluminum, stainless steel, copper, brass, and more. The choice of material depends on factors such as desired strength, corrosion resistance, weight, cost, and specific application requirements.

Cutting and Shearing: Sheet metal is typically cut into the desired shape and size using various methods. Common cutting techniques include laser cutting, plasma cutting, waterjet cutting, and mechanical shearing. These methods provide precise and clean cuts, ensuring accurate dimensions for subsequent forming processes.

Forming and Bending: Forming and bending are crucial processes in sheet metal fabrication to create three-dimensional shapes from flat sheets. Press brakes are commonly used to bend and shape the metal, allowing for the creation of angles, curves, flanges, and other structural features. Roll forming and stamping processes may also be employed for specific applications.

Punching and Perforating: Punching involves creating holes, slots, or other patterns in the sheet metal. Punching machines use specialized tooling to cut through the material, enabling the incorporation of fasteners, ventilation, or aesthetic features. Perforating is a similar process that creates a pattern of regularly spaced holes in the sheet metal for specific functional or decorative purposes.

Welding and Joining: Welding is employed to join multiple sheet metal components together to create a larger assembly or structure. Common welding techniques used in sheet metal fabrication include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and spot welding. These methods ensure strong and durable connections between the metal parts.

Finishing and Surface Treatment: After the fabrication processes, sheet metal parts may undergo finishing treatments to improve their appearance and enhance their performance. Surface treatments can include cleaning, deburring, grinding, polishing, painting, powder coating, or applying protective coatings to increase resistance to corrosion or wear.

Assembly and Integration: Sheet metal components are often assembled and integrated with other parts to create a final product or system. This may involve fastening with screws, rivets, or adhesives, as well as incorporating additional components such as hinges, handles, brackets, or electrical connectors.

Sheet metal fabrication offers several advantages, including high strength-to-weight ratio, versatility in design, cost-effectiveness for large-scale production, and suitability for both functional and decorative applications. It enables the creation of a wide range of products, from simple brackets and enclosures to complex structural components and machinery.

Since 2015, our expertise in the prototyping and production industry has aided both start-ups and established brands in crafting prototypes and products that stand out in the global market. Our commitment to quality and precision is reflected in our advanced machinery and the dedicated team of professionals who work diligently to deliver your products on time. We offer rapid prototyping services at competitive prices, ensuring you receive parts with exceptional precision through cutting-edge manufacturing processes such as CNC machining, 3D printing, vacuum casting, and sheet metal fabrication—all within short lead times.

With precision CNC machining services, Barana Rapid is your ideal partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your requirements for your drawing.

We also provide low-cost manufacturing of high-quality plastic parts. Our vacuum casting services offer short-cycle solutions for creating high-quality prototypes and low-volume production parts. Vacuum casting, or urethane casting, is a method that utilizes a silicone mold and a 3D printed master to produce vacuum-cast parts with consistent performance and production-grade quality. This technology does not require a costly initial investment, enables flexible and economical production, and hardens thermoplastic polyurethane in silicone or epoxy molds. The outcome is a vacuum-cast part that retains the shape of the original master model. The final dimensions of a vacuum-cast part are determined by the master model, the part's geometry, and the selected material.
