The bending, or press brake forming or folding, is a forming process in which the plastic deformation happens over an axis. Bending does not normally change the thickness of the sheet metal.
Punches and dies press brakes are used to perform this process. A die can be a lower V- or U-shaped tool. The plate is pressed into the die to made a bending part.
The CNC controls of our machines will precisely regulate the lowering depth and helps to maintain the minimum bending radius.
Materials of sheet metal bending parts. Those bending metal plates include SGCC galvanized plate, SECC electrolytic plate, SUS stainless steel (model 201 304 316, etc.), SPCC iron plate, white copper, red copper, AL aluminum plate (model 5052 6061, etc.), SPTE, spring steel, manganese steel.
As a professional china sheet metal manufacturer, HSJ Metal Fabrication performs all types of metal and steel bending. We can provide you with customized prototypes or designs according to your specific projects and needs.
Your product will be shaped accurately on time with minimal deformation and maximum consistency. Our years of custom sheet metal bending experience allows us the rare ability to carry out your demands for precision steel forming.
With our experienced workers, professional bent sheet service and multifunctional metal bending machine we can bend sheet metal panel from materials to custom-desired parts in any shapes and radii you need.
In the process of sheet metal bending, tolerances are inevitable. Tolerances within a certain range are allowed.
Our tolerances are less than 5.0 for sheets of ±0.1 and 5.0 or more for ±0.3. And those over the range should be caused by improper operation. What we need to do is to control the tolerance to the smallest possible range.
Therefore, when cutting the material, it is necessary to ensure that the tolerance of the plate shearer can be controlled. In addition, shear plates and CNC machining also play a significant role in sheet metal processing.
OEM Laser Cutting custom computer case sheet metal part，computer enclosure, computer host shell, computer chassis, accessories, cabinets, various of electronic precision metal bending parts. Material: Aluminum 5052, Carbon steel, Stainless steel, etc

The common applications of bent sheet metal parts are in the panels, enclosures, cabinets, etc. of automobiles and airplanes.
According to product functional, aesthetic and cost requirement, we choose the appropriate sheet metal materials. After selecting the materials, they should be verified and tested according to the product design requirements.
Bend allowance is defined as the material required to add to the total length of the panel metal in order for it to get cut in the required size.
The higher a metal's degree of elasticity is, the greater bend allowance it has. One of the most elastic metals is nickel titanium. The next most elastic metals include tin, magnesium, cadmium, and aluminum.
