Sheet Metal Stamping Fabrication refers to the bending and shaping processes of Sheet Metal Stamping techniques. Sheet Metal Stampings can be given all sorts of complex hollow shapes and sections, and the equipment used for these processes, range from simple hand tools, to sophisticated power-operated automatic machinery.
Sheet Metal Stamping work usually starts with a preliminary operation such as cutting, perforating or slitting etc. with tools that exercise some type of shearing action. These may be simple hand scissor like cutting tools, or power operated bench shears for heavier gauge materials. There are several kinds of power-driven shearing machines, and such machines comprises of a fixed blade and a moveable blade. The process of 'punching' refers to operations carried out with the use of a punching machine (or press) and this means to pierce a hole in the metal article, with the appropriate tool fitted in the machine, and clipping (the removal of surplus metal).
Another type of Sheet Metal Stamping fabrication is shaping. A wide range of shaping operations known as folding or bending, are done on presses and similar machines, as well as operations such as
Crimping & Beading
These processes are used for the stiffening and shaping of Sheet Metal Stampings, the forming of tubular sections for circular shapes, and other numerous purposes.
Angles and sections can be formed by bending or folding. Coiling is the process of coiling over the edge of a Sheet Metal Stamping component, to increase the strength and provide a suitable edge, and is applied by a rolling or coiling tool on a press. Circular or cylindrical shapes such as tubes are performed and produced on a roll-forming machine. Press forming operations can include
Cupping refers to the conversion of a blank into cup form. Embossing refers to a particular design applied for strengthening purposes, and can be produced on a partly finished component. Cupping is usually the first stage in an operation known as forming, in which the appropriate tool is used to give the article its final shape. Seaming is generally used for joining Sheet Metal Stamping parts and is for example, often used for joints in metal roofing. Flanging is the process of forming a flange on a Sheet Metal Stamping component. Beading is the process of making depressions for the purpose of embellishment or stiffening, etc, and it may be done by the use of suitable or specifically shaped rollers. There are many other techniques used in Sheet Metal Stamping fabrication and some of these can include:
With the advancement of today's technology, many of these techniques are now applied with the use of computer controlled machinery.
Metal fabrication is a process of producing a metal component by modifying a raw piece of material in a machine shop. These materials are processed on different temperatures and depending on the range of temperatures; the process is classified as cold, warm and hot. Precision Sheet Metal Stamping fabrication describes various different processes that form Sheet Metal Stamping into finished products. Objects that are fabricated and used for machinery and other instruments are among the daily used objects like paper clips, computers, bolts, nails, automotive parts and many more.
There are various factors like rate of production, desired geometry, and other physical requirements that influence the fabrication process. The benefits of the metal fabrication process are far and wide because it is used by all industries. Every precision Sheet Metal Stamping fabrication process undergoes three primary processes that include forming, cutting and finishing. Forming is a process that alters the form of the flat metal sheet.
