Why do we need to add coolant to the shield during production? 【Hardware】

The production of shielding covers not only needs to pay attention to the size of flatness, but also has high requirements on the surface of the product. There must be no indentation, no scratches, and no dirt. With the continuous improvement of industry technology, more and more factories use high-speed punches to produce shielding covers. Ordinary size shields can be punched per minute at a speed of 200-250 using a high-speed punch. Some smaller shields can be produced at a speed of about 350-400 strokes. Of course, this speed must have a powerful mold. Even the best mold will generate heat, expand, accelerate wear, and damage the life of the product under such high-speed work. So many manufacturers are dripping coolant while producing. First, it drops on the raw material, passes through the material strip of the shielding cover, and enters the mold cavity to cool the temperature of the mold steel plate and the temperature of the various inserts and knife edges in the mold. Ensure the normal operation of the mold and ensure the stable quality of the product. Then after the mass production is finished, it is cleaned and packaged again.
