Causes of pitting in metal stamping parts

Metal stamping parts are commonly used in all walks of life in everyone's daily life, including some automotive stamping parts, electronic stamping parts, stainless steel stamping parts, and precision stamping parts. During production, it is found that stamping parts, shielding covers, CNC machine tool covers and other hardware stamping parts have poor surface precision and pitting. How to deal with this kind of situation? You must first grasp the cause of the pitting. Because the plan view of the cavity contains dirt, the uneven surface of the product is called pitting. The causes of pitting are as follows: ①The dust around the press falls and sticks to the mold or raw materials (due to the natural environment). ②The presses in front of the windows and around the passages stick to the molds and raw materials due to wind or dust blown in and out of the workshop (due to the natural environment). ③The passages around the press are based on the steam discharged from the electric forklift, causing dust to fly (due to the natural environment). ④ When using a mold, suck in flying sand or dust from the air outlet, which may cause pitting (mold problem). ⑤When applying processing oil on the blank, the hair of the brush falls off and sticks to the blank; or when the oil is rubbed with a drum, the slag falling off the drum is coated with the oil (difficulty in moisturization) ). ⑥When cleaning the embryos, because the cleaning is not clean, the 'whisker-like substances' in the residual falling material (cleaning problem). 【related suggestion】
