Thin Membrane Punches

Plastics/Metal Foils

Punching thin plastics and metal foils requires exceptional precision and accuracy. While typical punch & die clearance for metal stamping ranges from .001” to .005”, thin membrane punching demands tolerances as tight as .0001” —equivalent to the thickness of a human hair (~.002").

Graphite coated Anodes/Cathodes

Producing graphite-coated anodes and cathodes requires specialized expertise. At Punch Tools, we use advanced techniques and equipment to deliver clean-cut edges and prevent graphite crumbling, ensuring the durability and performance of battery components.
