Sheet metal is a highly practical material that is reasonably practical in the manufacturing industry. Its widespread use spans from intricate components in electronics to robust panels in automotive bodies. To achieve this practicality, fabrication is a must. Sheet metal fabrication encompasses various processes used to shape, cut, and assemble these metal sheets into desired forms and sizes. This process can include various techniques replying to the specific requirements for a certain manufacturing project, including the type of metal, its thickness, and the complexity of the design.
So, in today’s article, we are going to show you about sheet metal fabrication techniques comprehensively. Let’s delve in!
5 Commonest Sheet Metal Fabrication Techniques
Several core sheet metal fabrication techniques are used to transform raw materials. Cutting, bending, and finishing allow for intricate part design and high-volume production runs.
- Cutting
Laser and waterjet cutting technologies utilize a laser beam or high-pressure water stream to accurately cut sheet metal profiles. They can achieve tight tolerance cuts ideal for complex geometric shapes or prototypes. It’s because they feature clean edges and precise control. Meanwhile, plasma and oxy-fuel cutting are well-suited to thicker plate and structural steel applications.
- Bending
Mechanical and hydraulic brake is another common sheet metal fabrication technique that presses precisely form sheet metal into bent configurations. They achieve this by applying calibrated pressure along preset bend lines. During this process, the related CNC technologies perform bending operations with computer-controlled accuracy and high dimensional consistency.
- Hemming
This technique finishes cut or stamped sheet metal edges with a solid yet clean folded hem. It’s different from techniques like welding, which use added materials. Hemming securely binds the raw edge underneath for a smooth appearance. Such sheet metal fabrication technique is well-suited to exposed applications, improving overall part quality and longevity.
- Polishing
Materials removal processes like buffing, grinding, and sanding are applied to create a reflective or aesthetically finished surface on sheet metal components. They precisely level and refine the metal surface through controlled abrasion for a smooth, high-sheen appearance. It is preferred for trim parts and exteriors requiring an attractive style.
- Plating
Electroplating sheet metal fabrication techniques apply thin metal coatings like zinc and copper onto base metals. The purpose is to impart properties, including corrosion resistance and conductivity. This passivates the underlying material’s surface chemistry. The plating’s barrier effect also helps extend functional product life expectancies.
Significance of Sheet Metal Fabrication Techniques in the Manufacturing Industry
Sheet metal fabrication techniques facilitate mass production on versatility, efficiency, and adaptability, which are essential for meeting the diverse needs of modern manufacturing. Talking specifically, here’s how:
- Versatility & Customization: Can be used across various industries like automotive, aerospace, and construction for different applications and cater to precise custom designs essential for specialized applications
- Cost-Effectiveness: Allows for the economical production of parts in medium to high volumes with minimal waste
- Innovative: Delivers continuous advancements, such as CNC and laser cutting, to enhance precision and open new design possibilities
Applications of Sheet Metal Fabrication
As mentioned above, different sheet metal fabrication techniques drive a diverse range of applications by transforming raw stock into finished components. Industries such as automotive manufacturing and construction rely on the formability and precision of fabricated sheet metal parts.
- Automotive Parts Production
Over 30% of global sheet metal consumption can be attributed to automobile manufacturing[1]. Automakers require sheet metal’s strength and versatility to produce body panels, chassis, engines, and numerous internal parts. Collaborations between automotive leaders and providers like BYD and Toyota will drive opportunities. It’s because eco-friendly vehicles require customized metal components[2].
- Architectural Material Manufacturing
The construction industry uses sheet metal for durable roofing, ductwork, facades, and more. Plasma cutting creates ornate facades and flashing from designs. Hemming finishes straight-cut aluminum panels for siding. HVAC, in particular, drives sheet metal fabrication for air ducts and vents before assembly on-site[3].
