The Gund Company manufactures custom-engineered materials with state-of-the-art fabrication capabilities. Found in automotive, eVTOL, and recreational applications, our composite, thermoplastic, and elastomeric materials serve as a solution in various areas. The Gund Company can provide short lead times on prototypes while also offering material selection guidance and collaboration.


Battery Applications

The Gund Company understands the challenges associated with designing a low-profile, lightweight, and high-capacity battery while also mitigating issues that could lead to safety concerns. We offer materials for thermal and electrical insulation, sealing, EMI shielding, and structural composites to help our customers overcome challenges discovered while designing an optimal battery.


The Gund Company manufactures custom molded composites for battery packs, endplates, and bracket applications. Our molding and additive manufacturing capabilities allow us to provide a custom solution to ensure our customers achieve the best performance possible.


  • SMC molding for rapid production of custom-designed high-strength composites
  • Significant weight savings over traditional materials such as steel and aluminum
  • Naturally insulating and non-corrosive for a longer-lasting, cooler battery



Thermal and electrical insulating materials from The Gund Company help dissipate heat and prevent thermal runaway or dielectric breakdown.


  • Films and plastics protect while reducing weight and space requirements.
  • UL94-V0 rating extinguishes flame for use between cells and within modules
  • Conducive to a wide range of forming and converting techniques to fit complex shapes at a low cost


Gaskets and Sealing

Sealing devices are essential to maximize performance of an EV battery. Gasket and sealing solutions from The Gund Company provide numerous benefits.


  • High-temperature silicone prevents degradation in higher the optimal temperatures
  • EMI Conductive elastomers provide shielding protection and seals a module or pack
  • Coextruded elastomers can serve two functions such as heat dissipation with high thermal conductivity, and high-temperature sealing


Charger Applications

The Gund Company specializes in insulation materials used in power supply, conversion, and distribution equipment. We manufacture materials and fabricate components used for inverters, rectifiers, and power supplies associated with DC and AC Electric Vehicle chargers.

Power Equipment Insulation

Power conversion equipment within a battery charger requires insulation to prevent static discharge between components. The Gund Company provides enclosure insulation and PCB liners to prevent this discharge.


  • High dielectric strength to prevent breakdown
  • Thin gauges protect tight spaces
  • UL94-V0 flame rating


Battery charging systems must withstand the outside elements daily. Sealing materials are essential to prevent moisture or debris from entering the charger leading to equipment failure.


  • Prevents moisture or debris from entering the charger
  • A wide selection of materials provides a perfect solution based on application requirements
  • Durable materials provide sealing for the duration of charger operation


The Gund Company manufactures and fabricates high-impact strength polycarbonate to protect components in a battery charger.


  • High impact strength polycarbonate prevents damage from the elements or vandalism
  • Easy to clean and moisture resistant
  • Transparent to be used in front of display equipment or opaque for other areas
