Automotive stamping parts of the bulk and dimensional accuracy

Automotive stamping dozen big is: inside and outside the plate cover, roof, fender, big side plate around the left and right sides, trunk inside and outside the plate, the door inside and outside the plate before and after, before, during and after the floor. Automotive stamping parts many classes, different types have different parts used in the steel plate. Some of performance requirements is not high and shape are not complex sealing plate, support of what will use tensile properties general steel plate; Large outer covering parts because of cosmetic requirements will use the special requirements of the steel plate; Some relatively complex shape, a dark shape or change the characteristics of relatively rapid thing to keep good tensile properties of the steel plate; Dimension precision metal stamping parts generally can be divided into two categories, precision level and common. Precision level is on the stamping technology can achieve the precision, and regular grade is can use economic means to achieve accuracy. When high precision mould manufacturing, metal stamping parts dimension accuracy can reach ITl0 level, inner hole size can achieve IT9 level. The surface of the metal stamping parts quality should not be higher than that of the surface quality of raw materials, or need to increase the subsequent processing to achieve, increased the cost of production. Metal stamping parts size accuracy refers to stamping the difference between the size of the basic actual size, the smaller the difference, then the higher the precision metal stamping parts size. A major cause of metal stamping parts size error are: the manufacturing precision of convex and concave mould; Convex and concave die clearance; After stamping materials elastic recovery; The accidental factors in the process of production, such as inaccurate positioning, material performance is not stable. Co. , LTD. , dongguan city, the main production of various kinds of stamping parts, stretching pieces, metal assembly parts and other metal mechanical parts. Company mainly on technical strength, in the production of precision machinery parts, household appliances parts, auto parts and other industries in the success of the production and management experience, the company has passed ISO9001:2015 quality system certification. The factory now has 2 ~ 315 tons punch more than 60, more than 30 Taiwan mold machining equipment, and another lathe, grinding machine, milling machine, shearing machine, welding machine, spot welding machine and other supporting facilities.
