1, the use of die to separate the plate stamping process.
2. High precision metal stamping shrapnel should be based on the difference of punching variation principle. Punching can be divided into general punching and high precision punching.
3. For most of the punching die, the precision of punching production has an important impact on the precision of the specification of the parts.
4, the greater the accuracy of the stamping die, the greater the accuracy of the metal shrapnel stamping parts.
