Changzhou metal stamping parts manufacturer, regarding dimensional tolerance + stamping accuracy up to 0.01mm

Changzhou hardware stamping parts manufacturers have introduced that 'GB/T13914-2002 Dimensional Tolerance of Stamping Parts' stipulates the dimensional tolerances of stamping parts. Dimensional tolerances are specified for flat stamping parts and forming stamping parts. The dimensional tolerance value of stamping parts is related to the two dimensions of stamping part size and plate thickness, and on the other hand, it is related to the accuracy level. The following Xiaoshuo brings you a long knowledge: Flat stamping parts dimensional tolerance: divided into 11 grades, represented by ST1 to ST11, among which ST represents the flat stamping part dimensional tolerance, and the tolerance grade code is represented by Arabic numerals. From ST1 to ST11, the accuracy level decreases in order. Dimensional tolerance of forming stamping parts: forming stamping parts are divided into 10 accuracy grades, which are represented by FT1 to FT10, where FT represents the dimensional tolerance of forming stamping parts, and the Arabic numerals indicate the tolerance level. From FT1 to FT10, the accuracy grades decrease in order. The limit deviation of stamping parts: the hole size press deviation is 0, the upper deviation is the lower deviation plus the dimensional tolerance; the shaft size specifies that the upper deviation is the basic deviation, and the value is 0, and the lower deviation is the upper deviation minus the dimensional tolerance. For the distance between the holes, the edge distance of the holes, the length and height of bending and drawing, the upper and lower deviations are stipulated as half of the dimensional tolerance. Hardware, 15 years of ingenuity focused on metal stamping parts processing, 20000+ sets of stamping die customization production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality inspection layers are strict check. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
