Battery and power systems

Battery and energy systems to power devices come in different sizes such as button cell, cylindrical, pouch, stacked, acid and multi-pack for larger devices. GF Machining Solutions offers EDM and Milling solutions to accurately manufacture devices such as cathode and anode spreader tools or plastic housing injection molds for battery systems. Forming, bending, cutting die tool set for connection leads and tabs is also possible.

Stamping tool for battery cathode and anode leads

Battery, fuel cell and other electrical power devices require the creation of cathode and anode leads through progressive stamping technology. These leads directly impact the energy efficiency and transfer rate, thus require extremely accurate tooling with fine edges and high surface finish. With our Wire EDM machines:

  • Enable machining of carbide and steel with an integrated technology
  • Obtain high accuracy on machined components due to robust machine design
  • Achieve superb surface finish with Thin Wire technology
  • Control the quality with integrated advanced systems such as ISPS (Intelligent Spark Protection System), IVU (Integrated Vision Unit) and AWC (Automatic Wire Changer)

Micro-scale lead features

To reach miniaturization and energy efficiency, modern battery systems used in electric vehicles, solid state devices and fuel cells need micro-scale lead features. Our state-of-art high-end Wire EDM with Thin Wire technology allows the creation of tooling suitable for these applications.

  • Accurate machining of smallest geometries
