Thin Membrane Punches

Plastics/Metal Foils

Punching thin plastics and metal foils is a delicate operation that requires a great deal of precision and accuracy. Typical punch & die clearance for metal stamping is .001” - .005”. For thin membrane punching the tolerance is in the .0001” range (human hair is approx .002").

Graphite coated Anodes/Cathodes

Producing graphite coated anodes and cathodes is a specialized process. We have the knowledge, experience and equipment to produce graphite coated anode/cathode with clean cut edges and no crumbling graphite.

Producing these materials efficiently and effectively with Punch Tools will ensure that your battery cells have strong and durable components.
