What is laser perforation?
Laser Perforation aims to creat mini-holes in all kind of materials with extreme thin thickness, Materials include Copper Foil, Aluminum Foil, Film and so on. inside the materials, copper foil perforated usually intend to fit battery usage, film with perforated holes usually aims to creat easy open tear line or other purposes.
What is the difficulty to perforate in Copper Foil?
- Traditional Die Cutting, easily break off, impression, burr, causing materials waste
- Small amount, heteroideus materials cannot undertake high cost of traditional die cutting
Laser perforation on copper foil
Laser perforation could easily creat holes in copper foil with high speed, cause of the extreme thin materials, especially Ultraviolet Laser, with its cold processing, could perforate holes in copper foil precisionly, hole diameter could controlled in 6-12 micron.
