As a stainless steel fabrication factory, Shenzhen HSJ Metal Fabrication Co., Ltd. offers research and development, production of metal fabrication and various kinds of industrial parts like sheet metal stamping parts and custom sheet metal bending. HSJ sheet metal fabrication factory was established in 2015 and owns 5 years of experience in this field. HSJ adopts advanced precision metal forming & cutting technologies to provide high-quality sheet metal fabrication services.

The sheet metal chassis is a chassis that is required for the use of a comprehensive cold working process for metal sheets (usually below 6 mm). Processing techniques include shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming (such as car body). Its remarkable feature is the same thickness of the same part. The chassis made of sheet metal can meet the various functions and appearance requirements of the chassis, such as metal chassis for robot and custom aluminum chassis. The metal chassis can make the stamping die manufacturing at a low cost.

Process Technologies in Sheet Metal Chassis Fabrication

The sheet metal processing chassis is an important part of the sheet metal processing industry. The manufacturing process of sheet metal chassis requires a lot of technology.

(1) Welding: Welding processes mainly include arc welding, electroslag welding, gas welding, plasma arc welding, fusion welding, pressure welding, brazing and so on.

(2) Stretching: The radius of curvature between the bottom of the pull tab and the straight wall should be b, that is, r1≥t, generally r1=(3～5)t, and the maximum radius of curvature should be less than or equal to the thickness of the plate 8 times of, that is, r1≤8t.

(3) Blanking: According to different processing methods, blanking can be divided into ordinary blanking, counting punching, shear cutting, laser cutting, wind cutting, etc.

Sheet Metal Chassis Materials

Different uses of CNC chassis determine the design and the selection of material. For vehicles, the material used for the construction of the chassis is usually carbon steel, but it is also becoming more commonplace that they are made up of aluminum alloys considering its light-weight characteristic.

Materials for chassis CNC: 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.
