When sourcing a perforation machine, you must prioritize mechanical precision and material compatibility. Key specs include the maximum punching thickness (measured in mm), the perforation speed (strokes per minute), and the hole diameter range. For industrial applications, ensure the machine features CNC control systems for high accuracy and adjustable feed rates to prevent material tearing. Additionally, verify the die-set durability, ideally made from high-speed steel (HSS) or tungsten carbide, to ensure a long service life under heavy workloads.
