Sheet metal hardware

Sheet metal is a comprehensive cold working process of metal sheets (usually less than 6mm), including shearing, stamping/cutting/compounding, folding, welding, riveting, splicing and forming (such as car bodies). Generally speaking, the basic equipment of a sheet metal factory includes shearing machine, CNC punch/laser machine, plasma, waterjet cutting machine/compound machine, bending machine and various auxiliary equipment.

Sheet metal processing is called sheet metal processing. Specifically, for example, use plates to make chimneys, iron drums, fuel tanks, fuel tanks, vent pipes, elbows, sizes, circles, funnels, etc. The main process is cutting, bending, bending, forming, welding, riveting and other geometric knowledge.

Sheet metal parts are thin metal plate parts, that is, parts that can be processed by stamping, bending, and stretching. The general definition refers to parts with constant thickness during processing. The corresponding parts are cast parts, forged parts, machined parts, etc. For example, the outer shell of a car is sheet metal, and some kitchen appliances made of stainless steel are also sheet metal.

Modern sheet metal technology includes: filament power winding, laser cutting, heavy processing, metal bonding, metal wire drawing, plasma cutting, fine welding, rolling, sheet metal bending, die forging, water jet cutting, fine welding, etc.

The surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, because it has the function of preventing parts from rusting and beautifying the appearance of products. The surface pretreatment of sheet metal parts is mainly to remove oil stains, oxide scale, rust, etc., and to prepare the surface post-treatment. The post-treatment is mainly spray paint (baking paint), plastic spray paint and anti-rust paint.

The metal plate is characterized by light weight, high strength, good conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. At present, it is widely used in electronics, communications, automotive industry, medical equipment and other fields. For example, in computer cases, mobile phones and MP3, sheet metal is an essential part.

With the increasing application of sheet metal, the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers are proficient in the design skills of sheet metal parts so that the designed sheet metal meets the product requirements. Function and appearance requirements can make the manufacture of stamping dies simple and low-cost.
