Choosing the Right Method
Metal components can be created to fulfill a wide range of functions, from business signs and food processing equipment to architectural embellishments and structural supports, using two popular methods: metal stamping and precision sheet metal fabrication. Let’s contrast these two procedures and discover the benefits and drawbacks of each.
Metal Stamping
Metal stamping requires a press to form a metal sheet into the required shape. This can be done using various techniques, including bending, blanking, punching, coining, and flanging. Sometimes the shape can be created using just one of these metal stamping techniques. One or more forms of metal stamping may be employed for more complicated applications.
Metal Stamping Benefits
The use of metal stamping in mid to high-volume manufacturing is a financially viable option. The processing of huge volumes and intricately crafted shapes is more effectively offered. It is a procedure that can also be mechanized to boost output and minimize scrap wastage.
Constraints With Metal Stamping
The prolonged setup time associated with metal stamping is its major drawback. Developing specialized tooling for metal stamping can delay pre-production. Additionally, after the tooling is created, changing the design becomes challenging. Metal stamping is better suited for mid-to-high-level volumes because of the lengthier setup time, which results in a higher price-per-piece cost.
Flat Sheet Metal Fabrication
Plasma cutters and other specialized fabrication technologies can process flat sheets of steel, aluminum, and other metals. Fabricating metal sheets involves a variety of sub-processes, such as cutting, welding, forming, and bending, similar to stamping. Precision sheet metal fabrication has practically limitless possibilities, but it is especially well suited for producing functional pieces like brackets, panels, and enclosures.
Advantages of Flat Sheet Metal Fabrication
Making unique components out of sheet metal using a plasma cutting table or equivalent machinery allows far greater freedom and variety. In contrast to stamping, sheet metal fabrication has a quick startup time, making it significantly more effective (and cost-effective) for smaller production runs. CNC capabilities can be added to plasma cutters to automate fabrication and reduce cutting errors.
Cons of Manufacturing With Flat Sheet Metal Fabrication
Burn tables are often labor-intensive, but this disadvantage can also be overcome by using CNC controls, which frequently require just one specialist. Another drawback is that the amount of detail incorporated into the shape is constrained; metal stamping will yield superior results for detailed designs.
