Punching/Drilling is a common processing term in foreign trade, referring to punching or drilling holes in products (such as metal, plastic, paper, leather, etc.) according to customer requirements. Usage scenarios include: customer drawing processing, custom parts, packaging punching, hardware punching, etc. Precautions: It is necessary to clarify hole diameter, hole spacing, tolerance, hole position, punching method (punching or drilling), whether chamfering is required, deburring, etc.; different materials are suitable for different processes, such as thin plates use punching, thick plates or high precision use drilling. Difference from terms such as 'cutting' and 'stamping': punching only refers to forming holes, not involving shape separation; stamping may include multiple processes such as punching, forming, and blanking. Foreign trade contracts should specify punching standards in detail (such as ISO, DIN) to avoid disputes caused by misunderstandings of the process. In addition, punching may affect product strength, and it is necessary to confirm whether reinforcement is required.
