Metal stamping parts, precision parts blanking dimension tolerance is plus or minus 0.
Metal stamping parts dimensional accuracy is measured by the tolerance of registration, the nation is divided into 20 grades, from IT01, IT0, IT1, IT2 ~ IT18, number, the greater the tolerance grade (
The machining accuracy)
Changes in the lower dimensions allow range (
The tolerance value)
The smaller, the greater the processing difficulty of metal stamping parts size accuracy refers to the stamping parts and basic size of the actual size difference, the smaller the difference, metal stamping parts dimensional accuracy is higher.
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 dimension precision metal stamping parts generally can be divided into two categories, general grade and precision.
Regular grade is can use economic means to achieve accuracy.
Precision level is on the stamping technology can achieve the accuracy of precision, a professional design and manufacture of precision stamping die and precision metal stamping parts of ODM/OEM professional manufacturers.
Terminal shrapnel stamping with high efficiency, high precision products unit price advantages, mould precision of the whole of plus or minus 0.
002 mm, terminal, shrapnel dimension tolerance can guarantee baiting size & plusmn;
001, the size of the bending & plusmn;
Less than 3 mm, stable quality, stable performance, high output precision contact: precision I wish you all brisk business and everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public.
