The thickness of the air conditioner front baffle sheet metal is generally 3cm.
Sheet metal is a processing technology. Sheet metal does not yet have a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching/cutting/compositing, folding, riveting, splicing, Molding (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is consistent.
Sheet metal has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. It is widely used in electronic appliances, communications, automotive industry, medical equipment and other fields. It has been widely used, such as in computer cases, mobile phones, and MP3 players. Sheet metal is an essential component. As the application of sheet metal becomes more and more widespread, the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers must master the design skills of sheet metal parts so that the designed sheet metal meets the requirements of the product. Requirements such as function and appearance can make the manufacturing of stamping molds simple and low-cost.
Ordinary cold-rolled plate SPCCSPCC refers to steel ingots that are continuously rolled by a cold rolling mill into steel plate coils or sheets of required thickness. There is no protection on the surface of SPCC. It is easily oxidized when exposed to the air. Especially in humid environments, the oxidation rate accelerates and dark red rust appears. The surface must be painted, electroplated or otherwise protected during use.
