The application scope of the sheet metal processing industry is constantly expanding, ranging from daily necessities to industrial appliances, all of which involve the skill of sheet metal processing. Sheet metal chassis is a common product we encounter, such as computer hosts, switch enclosures, etc. So how to control the processing quality of sheet metal chassis and cabinets?
When we receive an order for a sheet metal chassis casing, it is necessary for us to have a comprehensive understanding of the product's appearance requirements, size requirements, and usage. After understanding the user's needs for the product, choose different processes based on the products of different users, and explain the precautions in the design drawings. Send the drawings to the manufacturing process diagram of the engineering section, and the craftsman will make the drawings for inspection by other staff. After inspection, it is necessary to sign and acknowledge them and send them to the workshop.
In terms of CNC cutting, a comprehensive inspection should be conducted on the first workpiece of CNC cutting, including dimensions, opening, etc. In batch production, it is necessary to review all the first batch in order to proceed with mass production. When bending, the bending direction and size should be determined first, and mass production should begin after confirmation. Please review again when replacing the operator or replacing the mold. The dimensions of welded or bent products shall be sampled according to the drawing requirements, and each dimension shall be recognized during sampling inspection. At the same time, a comprehensive inspection of the appearance should be carried out, and unqualified products should be adjusted in a timely manner and re checked. Fill out the verification statement together.
In terms of surface treatment, a comprehensive inspection was conducted on the appearance of the externally treated products. Products that have not passed the inspection shall not be shipped. The same product shall be inspected by the operator, and after passing the inspection, it shall be signed by the inspector. If the operator does not apply for inspection, there will be no labor cost for this batch of products. Although the customer's order is urgent, it is necessary to ensure the sheet metal processing concept of quality first and speed second.
Nowadays, there are more and more sheet metal chassis and cabinet processing products, and how to distinguish the quality of metal plate processing products is a necessary skill for us. Because the quality of the sheet metal casing directly affects the beauty and robustness of the product, special attention should be paid to its safety performance while ensuring the overall planning and design of the sheet metal chassis and cabinet to be effective.
