What are the surface quality inspection methods of high-speed press stamping parts?

   The following are some surface quality inspection methods for high-speed press stampings:
    Visual inspection: By directly observing the surface of stamped parts with naked eyes whether there are obvious defects, such as scratches, indentations, cracks, etc.
    Touch inspection: touch the surface of the stamping parts with hands to feel its flatness and roughness, etc..
    Roughness Measurement: Use roughness measuring instrument to accurately determine the surface roughness value.
   Glossiness Measurement: Check the glossiness condition of the surface.

   Dimension Measurement: Check whether the dimensions of the stamped parts meet the requirements, which indirectly reflects the surface quality.
    Flaw detection: such as ultrasonic flaw detection, magnetic particle flaw detection, etc., used to detect whether there are internal defects extending to the surface.
   Dye penetration detection: It can find the surface subtle cracks and other defects.
   Image Measurement: Image measuring instrument is used to obtain images of the surface of stamped parts for analysis and inspection.
   Profilometer Measurement: Measures the shape and characteristics of surface contours.
