Metal Fabrication

Fabrication refers to the building of machines and structures by cutting, shaping, and assembling components made from raw or semi-finished metal materials. Fabrication encompasses a wide variety of operations that are performed on thin sheets of metal. Metal fabrication generally concentrates on the preparation of metal by heating, melting, solicitation, followed by welding, bending, punching, and then assembling various parts of a machine or device.
Metal Fabrication is used for making larger assemblies or end products. Metal fabrication can be broadly divided in to two categories. Heavy fabrication describes manufacturing of cranes, bridges, and big ship structures. Light fabrication applies to the manufacturing of small goods, such as paper clips, computers, bolts, nails, automobile parts, and metal chairs. The process of metal fabrication may involve one or many of the following processes: Stamping, cutting, bending, forming, pressing, drilling, laser cutting, waterjet cutting, plasma cutting, gas cutting, and welding. The fabricator needs a broad understanding of metal forming techniques.
The expert team at www.emachineshop.com not only has an excellent understanding of fabrication processes but also fabricates shapes using their free downloadable 3D CAD software. The company services include bending, punching, drilling, turning, grinding, and threading, and all other aspects of metal fabrication.
The process of fabrication may become cumbersome and many manufactures are not interested in doing short-run jobs. www.emachine.com provides for production runs as short as one unit to a million.
Metal forming and its related processes involve forming by compression. This is at the heart of forging, rolling, extrusions, drawing, deep drawing, bending, spinning, and turret punching. A work-piece is given its final shape through machining operations, such as broaching, boring; twist drilling, turning, counter boring, spot facing, countersinking, reaming, milling, and grinding. Non-traditional machining methods are slower and require higher energy.
Metal Removal techniques refer to metal cutting, abrasive processes, and non-conventional metal removing processes.
Advanced Metal Removal techniques like Laser Cutting, Electro Discharge Machining, Wire-cut EDM, and Water cutting jet are also available. As Metal fabricators, www.emachineshop.com is capable of joining metal parts together through different processes. Bolt and screw drilling/tapping aside, welding is used almost everywhere in the fabrication process. The procedure of welding will differ by heat source, pressure, and filler metals. Heat and filler metals are used for connecting metal surfaces in brazing and soldering actions.
Occasionally, eMachineShop gets questions about the different ways to join metal parts. Welding is where two or more pieces of metal are heated to such a high temperature that the metal flows directly flow together. Brazing uses a slightly cooler temperature and an intermediate ‘filler’ material that metals are a lower temperature than the metals being joined. Brass and copper alloy rod is commonly used. Soldering offers the lowest temperature bond using a mixture of tin and lead. Producing a weaker joint, soldering is generally used where mechanical strength is not paramount, but where a metal seal or electrical conductivity is required, such as in electrical components.
