How does the hardware control the flatness of the shielding cover within 0.07mm

During the years working in the metal stamping factory, many technical cases have occurred in the workshop. For example, the RS-66810 shield produced today. How does Xiaoshuo control the flatness of the shielding cover? This metal stamping shielding bracket, because the product size is relatively large, the structure is relatively weak, the material is 0.15 thickness nickel silver, the surface of the product has only one patch nozzle position, and everything else is basically empty. Such a shielding cover with a complicated structure. The problem of dimensional tolerances is not a problem. However, because there are 13 solder joints, it is still very difficult to control the flatness within 0.07. First, Master Li assembles the mold, sets the mold on the machine, loads the material, and debugs. After the author has produced the shape, the quality inspection size is related. But the flatness is not enough. Mold repair and debugging. Re-repair the mold and then debug. After several mold improvements, the leveling block was adjusted. The hardware stamped out 100 first pieces to confirm, and all the good products were inspected. Sweat will not be wasted, and hard work will not be wasted. For every piece of metal stamping product that is shipped from the factory, every piece of shielding cover flatness that is controlled according to customer expectations, you can feel the smile of customer satisfaction!
