Custom sheet metal and fabrication

　　What is sheet metal? With the development of the industry and the need for modern fast models, precision sheet metal manufacturing services are increasingly used to produce small batches of parts to facilitate the development and testing of new products.

　　1. Sheet metal definition

　　Sheet Metal Fabrication a comprehensive cold working process for sheet metal (usually less than 6mm). The sheet metal process includes shearing, punching, cutting, compounding, folding, riveting, splicing, forming, surface treatment, and so on. The products processed by the sheet metal process are called sheet metal parts or sheet metal parts

　　2. Sheet metal equipment

　　Generally speaking, the necessary equipment for Sheet Metal Fabrication includes a Shearing Machine, CNC punch/laser, plasma, water knife cutting machine, bending machine, drilling machine, and various auxiliary equipment such as uncoiler, leveling machine, deburring machine, spot welding machine, etc.

　　3. Sheet metal software

　　In 3D software, SolidWorks, UG, Pro/E, SolidEdge, TopSolid, CATIA, etc., can be used to customize sheet metal processing services, mainly through the editing of 3D graphics to obtain sheet metal processing required data (such as expansion map, bending line, etc.), And provide data for CNC punch/laser, plasma, water cutting machine (laser, plasma, water cutting machine)/ combination machine and CNC bending machine, etc.

　　Sheet metal cutting

　　There are four main methods of sheet metal cutting:

　　A. Sheet Metal Fabrication shear: it is used to cut simple material parts with A shear machine. Mainly used for die blanking molding. Low cost, accuracy is less than 0.2, but can only process strip or block, no holes, and corners of the material.

　　B. Sheet metal punching service: the parts on the plate according to one or more steps to expand, with a punch out of the plane parts, the formation of various materials, its advantages are short time, high efficiency, high precision, low cost, suitable for mass production design mold.

　　4. Sheet metal CNC blanking. Numerical control blanking, the first to write numerical control processing program. Use programming software to program the pulled unwrapping into programs that can be recognized by CNC machine tools, and punch holes in the plates step by step according to these programs.

　　Cutting various shapes of the plate, but its structure is affected by the tool structure, low cost, accuracy is less than 0.15.

　　D, laser cutting is the use of laser cutting method, in a large flat plate to cut the structure and shape of the flat plate. As with CNC cutting, laser programs need to be written. It can load various complex shapes of flat parts, high cost, high accuracy, 0.1.

　　Sheet metal stamping

　　Customized sheet metal stamping is the use of mold and stamping equipment on sheet metal pressure, make sheet metal plastic deformation or separation, so as to obtain a specific shape, size, and performance of the parts (stamping parts)
