Sheet metal chassis and cabinet processing is the process of forming sheet metal into the desired shape using a variety of different manufacturing methods, including cutting, bending, welding, surface treatment, assembly and many other steps.
Usually, the process from chassis and cabinet sheet metal fabrication to metal products starts with drawing. After the drawing is completed, various parts are made through the sheet metal manufacturing process.
Laser Cutting
Laser cutting is the best choice for cutting chassis and cabinet panels. It is a very fast and accurate cutting method and is not limited by molds.
Such as 1.5mm plate, cut out smooth and smooth without burrs.
CNC Turret Punch Press
Punching is another method of cutting holes in the sheet metal industry, using a metal punch to impact the sheet to punch holes,
It is suitable for large-scale production. If it encounters regular shapes such as round holes and holes, CNC turret punching machines can be quickly realized by using die stamping.
Bending
Due to the complexity of bending, which can be the most difficult step in enclosure sheet metal fabrication, engineers must be intimately familiar with the bending properties of metal.
Welding
The welding process is to weld the cut and bent sheet metal parts into a box according to the production nature, drawings and technical requirements of the product, combined with the existing conditions.
Plastic Spraying (Surface Treatment)
The welded, spin forming and formed box is transferred to the spraying workshop for powder spraying after trial assembly.
Powder spraying is to spray electrostatic powder coating onto the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece, and then baked at high temperature to form a coating.
The surface of the product after spraying is dustproof and waterproof, and its adhesion, corrosion resistance, and aging resistance are superior to spray painting, and it is suitable for various outdoor harsh environments.
It is the surface treatment of choice when there are no special requirements.
Some chassis and cabinets will be directly transferred to assembly for assembly after the plastic spraying is completed, but there are also some that need to be printed with LOGO or patterns, which need to be transferred to the printing room for printing.
UV flatbed printer is a dark horse among industrial printers. Compared with the traditional silk screen printing process, its function is very powerful.
No need for typesetting, it can adapt to printing of different sizes, once formed, the pattern is beautiful and clear, sun-proof and waterproof, and the most important thing is that it is environmentally friendly and has no peculiar smell.
CNC Dispensing
Compared with traditional artificial sticking strips, CNC dispensing has firm bonding, smooth and beautiful surface, one-time molding without seams, strong adhesion, good elasticity, waterproof and dustproof.
Assembly
The final step of the finished chassis and cabinet is assembly! All the sheet metal frame and more are in place, just put it together and voilà!
