Factors for choosing sheet metal fabrication.

Factors for choosing sheet metal fabrication.

Sheet metal is one of the multipurpose materials in the manufacturing industry. It is generally made up of steel, brass, tin, titanium, aluminum, copper, nickel, or precious metals. It has different ranges in thickness from light foil to heavy plate. It can take different forms such as plain flat sheets, etched, embossed, corrugated, ribbed, and perforated. There are many applications of sheet metals including consumer electronics, aerospace, industrial furniture, appliance manufacturing, transportation, etc.

Sheet metal has many advantages over both non-metal alternatives and other metal fabrication processes. If compared with machining, sheet metal is cheap in processing as well as material costs. It does not have high tooling costs. In the process of machining, the expensive block of material is wasted in the milling process of removing unneeded material, whereas sin sheet material the unused sheet can be used for another project. The development of technology in current fabrication, automation, and new CAD programs are making designing in sheet metal easier and easier. Nowadays, CAD programs can design in the same material with which users intend to fabricate. There is no longer a need to create a separate set of drawings to understand the design.

Sheet Metal fabrication is a process in which smooth sheets of steel or aluminum are converted into metal products by folding, cutting, or punching. Sheet metal fabrication manufacturers usually make use of some dedicated tools like chops saws and band saws while performing the sheet metal fabrication process.

There are some factors for choosing sheet metal fabrications.

  1. Way of using the sheet metal: We can easily cut, form, bent, rolled, welded, stamped, punched, tapped, sheared, riveted, drilled, machined. Fer finishing sheet metal, it can be plated, anodized brushed, silkscreen, laser-etched, brushed, powder-coated, and pad printed. Like other technologies, the handling of precision sheet metal is continuously evolving. These days market is full of processes, tools, and equipment that are highly specialized and can be used to make common sheet metal parts. To fully use the technological advantages, it is necessary to select the accurate supplier and understand the differentiation between metal fabricators and other materials used in sheet metal fabrications.

  2. Types of sheet metals: There are some alloys and metals which comes in the form of sheet and are used in the fabrication of manufactured parts. The choice of material mainly depends on the final product of the fabricated parts. Common materials found inaccurate sheet metal fabrication include:

  • Aluminum: It is a natural corrosion resistance material, and it is one of the main reasons for Aluminium sheet metal as a popular choice in manufacturing sectors covering many application requirements. Grade 1100 suggestions outstanding corrosion resistance, high thermal and electric conductivity as well as excellent workability. It is usually found in transmission or power grid lines. Grade 3003 is a popular alloy used mainly for general purposes because of its moderate strength. Suggested heat exchangers and cooking utensils. Grade 5052 is an extensively used alloy best known for being the stronger alloys with the ability of formable, weldable, and corrosion-resistant. Grade 6061 is a solid operational alloy most used in high-strength parts such as trucks.

  • Copper/Brass – With less zinc content brass material can be easily cold worked, welded, and brazed. High copper content allows the metal to produce a caring oxide later on its surface that saves it from further corrosion. This oxide creates a highly desirable look found in consumer-facing products.

  • Cold Rolled Steel – There is a process in which hot-rolled steel is more processed for making it smooth and hold tighter tolerances when forming.

  • Stainless Steel – There are several options to choose from for sheet metal fabrication. Austenitic stainless is non-magnetic steel which contains high chromium and nickel and low carbon. They are the most widely used grade of stainless steel because of their formability and resistance to corrosion. Ferritic Stainless steels are magnetic steel that contains around 11-30% chromium and little or no nickel. These metals are usually found in the 400 series stainless steel. Martensitic steel is a group of chromium steels containing no nickel and developed to provide steel grades that are both corrosion resistant.

  1. Design considerations for fabrication: The workers designing sheet metal often end up redesigning them again and again. The reason behind these errors is generally the larger gap between the design and the final fabricated. The more designing engineer knows about the fabrication process while designing the more fruitful the manufacturability of the part will be. However, if there are few issues in the way certain features are designed, then a manufacturing supplier should be able to find them and suggest good alternatives. Some considerations while designing sheet metal for fabrication are Consider material thickness and manufacturers’ requirements while installing PEM hardware, welding thin materials can result in cracking or warping so consider other linking methods while working with thin materials, etc.

  2. Sheet metal fabrication methods/ techniques: There are several techniques of the sheet metal fabrication process. So, manufacturers should have the knowledge of all those techniques before starting any fabrication. Having the knowledge of different methods of fabrication will help the manufacture to choose the right technique according to the material and the need of the customer.

  3. Finishing sheet metals: There are several methods and reasons to finish sheet metal parts. According to the material chosen, some finishing techniques guard the material against corrosion or rust whereas other finishing materials are done for aesthetic reasons and in some cases, finishing can achieve both purposes. There are some finishing processes that include alterations to the surfaces of the materials whereas other finishing processes consist of applying a separate material to the metal. Finishing techniques usually include steps like brushing, plating, polishing, powder casting, etc.

At AccuGroup all these factors are considered before performing any sheet metal fabrication process. Sheet metal fabrication is done by our experienced manufactures with great knowledge of sheet metal fabrications.
