A. Production process of bar stock:
B. Production process of sheet metal:
C. Functions and standards of billet separation:
Exclude unqualified products before the next process
① The blank thickness is in accordance with the company's requirements for this product: the bar ± 0.2mm is the genuine product, and the plate ± 0.1mm is the genuine product (qualified product).
② The color and pattern change, which do not meet the requirements of the variety, is a waste product.
③ The model is poor, and the broken edge, core extraction and bubble are all waste products.
D. Production requirements and standards of the buckle workshop
① The shape is consistent with that of the sample, including the size of the fine edge buckle, the radian of the face and back, etc.
