Sheet metal fabrication comprises a wide range of methods that can often be confused, which is why we’ve created a beginner’s guide to the steps that we at DB Sheetmetals take to provide a comprehensive fabrication service.
What is Sheet Metal Fabrication?
In its basic sense, sheet metal fabrication is the creation of metal structures using a variety of processes. Most often sheets of steel or other metal materials are processed and assembled to create a larger final product and in order to bind these smaller components, methods such as welding are used to provide a high-quality finish.
Fabricated sheet metal has its applications in nearly every large industry today, from military and medical to telecommunications and automotive and our impressive and market-leading service has been utilised by many large companies across the country.
The Stages of Sheet Metal Fabrication
Design and Plan
Although each client approaches the design process in different ways, here at DB Sheetmetals, they are offered the opportunity to provide their own design specifications or discuss their needs in a consultation so we can help formulate a plan. This is an integral part of the process and can determine the economic efficiency and the best manufacturing approach to the project. Our expert design team is skilled in the applications of intelligent and high-tech computer-aided design (CAD software) and is vital in creating a quality final product.
Once the design has been formulated and finalised, they translated across to our market leading machinery which will create the item, this is known as the programming process. Parts are drawn and then “nested” in 2D form onto a metal sheet.
Once the machines have been programmed, the laser cutting process takes place. As one of the most precise ways of cutting sheet metal material, lasers reflect the design exactly and cut through the metal with ease and accuracy.
Various elements need specific perforations or forms such as ribs, louvres or countersinks. For this, a CNC punching machine uses special tools to “hit” the metal sheet and either perforate or shape it in specific ways according to the plan.
The bending process is a practice completed by our Amada and LVD press brake machines. Each machine forms the part by clamping the sheet metal within a top tool and die, applying force to obtain the intended shape and curve.
The assembly stage can differ depending on the complexity of the final product. Some assemblies require fastener installation which is the process of adding self-clinching fasteners using our Pemserter automatic fastener-installation press system.
The powder coating process is a process of applying an electrostatic powder to a charged metal component before curing at heat to produce a durable coating. Our state of the art fully automated powder paint line makes this process a breeze and produces incredible and flawless results.
