Potential failure modes of precision stamping parts
Precision stamping parts refer to the use of molds fixed on high-speed punches or presses to release certain pressure on metal materials or non-metallic plate materials, so that the raw materials are separated or formed, and then products with certain specifications and quality standards can be obtained. Next, Precision will analyze the potential failure modes in the production of precision stamping parts. The failure modes that are likely to occur in the daily management of precision stamping parts are: (1) When the raw materials are put into the warehouse, it is likely that the strength of the copper material is not enough due to the incorrect raw materials presented by the dealer or incorrect color markings. Condition, which in turn affects the characteristics of the product. (2) In the material requisition list, the wrong material was received because the raw material did not have an identifiable mark. (3) In the whole process of the stamping die, the stamping die SOP was not worked, which prompted the incorrect application of the stamping machine model. Failure to set the main parameters of the stamping die specification causes the die aspect ratio to be incorrectly set, and the mold assembly staff does not work in accordance with the die arrangement table, resulting in incorrect application of die parts and NG specifications. An abnormality occurred in the mold, and a poor prediction occurred. The staff did not work in accordance with the inspection standards, and products with crushing or cracks were manufactured. (4) In the whole process of product packaging, the staff did not work in accordance with the packaging standards, which caused the product to deform and twist. (5) The product is deformed by impact due to loose packaging during the whole process of product transportation.
