What are the maintenance techniques for UAV Micro Screws?
UAV Micro Screws are specialized processing equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). This is called a cold stamping die (commonly known as a cold stamping mold). Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part. 1. The die is loose or moves unilaterally beyond...
