With the more and more extensive application of sheet metal, sheet metal design has become a very important part of product development. Mechanical engineers must master the design skills of sheet metal skillfully, so that the designed sheet metal can not only meet the requirements of product function and appearance, but also make the stamping die simple to manufacture and low in cost. Spraying characteristics: spraying operation has high production efficiency and is suitable for manual operation and industrial automation production. Widely used in hardware, plastics, furniture, military industry, ships and other fields, it is the most widely used painting method at present. Spraying operation needs a clean workshop, and the environmental requirements range from one million to one hundred.
