Metal production experts use a variety of different techniques to produce customized parts, fittings, and other industrial and commercial solutions. Each technique produces a completely different product with different characteristics. Whether it is bar milling, sheet metal fabrication, or press brake forming, each has its own purpose and set of benefits.

Press Brake Forming

Using a computer operated press brake forming machine, which runs at extreme pressures of approximately 350 tons, this machine literally squeezes metal into shape. Many machines can work with up to a 3/8" thick material that is upwards of twelve feet in length. Press brake forming also works with a variety of different metals including brass, stainless steel, aluminum, and carbon steel. So what is it used for? If you need a metal housing for a particular part, brackets for machines and equipment, metal framing, and even decorative touches, this method will likely be the one used. This is an ideal solution for anyone needing replacement parts, large numbers of brackets, and fastening solutions as well as prototypes for almost any type of machinery.

Bar Milling

Bar milling is reforming an existing bar into a particular shape, form, and length to make it fit various jobs and specifications similar to running a router or shaper down a narrow length of wood. This could be by taking traditional round or square bars and making them into hexagonal or angled bars, adding grooves or other features down the entire length. It can also be made from various materials including brass and stainless steel. To create each shape, the specialist puts together a series of cutters that could be bevels, round overs, slots, and much more. Finally, it is milled down to a smooth surface and made into the proper dimensions.

Sheet Metal Fabrication

Sheet metal fabrication is ideal for detailing and precision cutting. With this method, specialists can use laser cutting, punching, press brake forming, shearing, and welding to create virtually anything from this super-thin and flexible metal product. It is used for everything from cultivator shovels and hopper bottoms for the agriculture industry to conveyor parts, guards, frames, decorative metal forms, and many other items for a variety of other industries.

Sheet metal fabrication works to build all sorts of covers and frames. It also works as a column cover or for ventilation purposes. Fasteners and other components are also made using this method. This includes many different parts involved in the transportation, refrigeration, and conveying sectors as well as amusement park rides and other recreational activities.

Depending on the task at hand, any one project could be subjected to one or a combination of these techniques. Then, welding is used to piece everything together to finish the completed project. Once that is complete, a quality provider will check the entire piece for quality, durability, and accuracy before handing it over for installation. Whether it is sheet metal fabrication, press brake forming, or some other technique, there is a process and the corresponding technology to produce the exact item you need.
