Consistent thickness of the same part;
Cold rolled sheet SPCC, mainly with plating and baking paint parts, low cost, easy to mold, material thickness ≤ 3.2mm. hot rolled sheet SHCC, material T ≥ 3.0mm, also with plating, baking paint parts, low cost, but difficult to mold, mainly with flat parts.
Sheet metal is a sheet metal (usually below 6mm) for a comprehensive cold working process, including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, molding (such as car body) and so on.
Expanded Information:
Sheet metal parts are characterized by light weight, high strength, conductivity (able to be used for electromagnetic shielding), low cost, and good performance in mass production, etc., and are widely used in the fields of electronic and electrical appliances, communications, automotive industry, medical devices, etc., e.g., in the case of computer chassis, cell phones, MP3s, the sheet metal part is the indispensable component.
With the wider and wider application of sheet metal, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must be skilled in the design of sheet metal parts, so that the design of the sheet metal meets the functionality and appearance of the product and other requirements, but also to make the stamping die manufacturing is simple and low-cost.
Sheet metal parts factory in general, the basic equipment includes shearing machine, CNC punch press / laser, plasma, water jet cutting machine / composite machine bending machine and a variety of auxiliary equipment, such as: uncoiler, leveling machine, deburring machine, spot welder and so on.
