How to Test Sheet Metal Parts?

1. Those affecting the final appearance and clearance, is as key dimensions (one of the biggest problems in the appearance of the company’s products is that the gap between the sheet metal is not the same, large and small seams are uneven, and it looks like cottage goods)
2. The fit dimensions of the assembly between the sheet metal, mostly between the studs and the fixed holes, the production of templates, the usual inspection with the template fit test, the actual production of the actual fit test in emergencies.
3. Machining surface correctness, compare with drawings or samples, (supplier level is also sub-par, each batch has 1-2 machining surface counter off)
4. Other dimensions, random inspection
