Metal fabrication processes provide several key manufacturing solutions. This article will cover the basics of metal fabrication in how we stamp, punch, bend, cut, mill, and weld metal materials. These include steel, aluminium, and brass metals to achieve high quality custom metal components.
Barton International calls upon the combined experience of Midlands based manufacturing as well as utilising global, low-cost partners.
The first metal fabrication processes we will cover is CNC metal stamping which is a very simple process. Where we design the metal fabricated part utilising CAD software, test and input the finished product data into our production equipment, ready for manufacturing.
Cold sheet metal (Referred as a blank) or roll is then placed or fed into an automated die-cutting press and stamped out into a custom shape with force.Metal stamping involves a wide range of manufacturing techniques, including punching, blanking, embossing, coining, bending, and flanging.
CNC metal punching is often confused with metal stamping, due to the wording of stamping and punching having very similar meaning. The first main difference is the machinery required to achieve punching or stamping.
The sheet CNC metal punching processes are formed utilising CNC machinery that utilise punch presses and dies. The punch passes through the sheet metal while the dies located on the other side of the metal piece operate as a support and help punches to put more force. Ensuring that the metal does not break under pressure.
Metal folding is the stage in metal fabrication which bends or folds sheet metal material or components into a pre-set angle utilising automated press brake machinery. This machinery uses powerful tensile force to fold and punch material into the required shape. Press Brakes can come in wide range of sizes/presses and can be configured to operate manually or automatically (automated) to support with high volume production.
Metal laser cutting is a very accurate and versatile method for cutting intricate metal shapes. The Laser cuts through the metal utilising a thermal separation process. Penetrating the metal through to the other side, following a path programmed via a CNC manufacturing process with uploaded CAD data.
CNC Milling is an automated manufacturing process in which cutters rotate, drilling and removing excess material to form the desired custom shape, cut or finish. This can be performed on small intricate parts as well as large ones. Milling machines perform substantially well for mainly metal, wood, and a variety of other solid materials. Performing several tailored operations, including slot cutting, threading, and rabbeting to routing, planning, and drilling.
Metal Welding is a metal fabrication process were metal is fused together. This is achieved through extremely high heat, achieving melting point to enable weld. There are several different energy sources for welding including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound.
One of our final metal fabrication processes are screws and fasteners. Which are usually manufactured out of steel, which offer excellent resistance to weather and corrosion. Other metal materials include stainless steel, brass, titanium, bronze, silicon bronze or monel. There is also a wide variety of custom screws and fasteners available, depending on product application. From a simple chipboard screw to security screws.
In its simplest form, the core manufacturing method for screws and fasteners is thread rolling. Were a cold metal spool is mounted on a spindle and gradually fed through a die cutting process, to give the screw its desired finish.
