Battery Encapsulation

For protection against external influences

Product information

KraussMaffei’s Battery Encapsulation technology uses fast-reactive polyurethane (PUR) to encapsulate battery cells, modules, or electronic components. This process provides thermal, mechanical, and environmental protection while enabling efficient high-volume production.

  • Material Preparation: Two-component PUR (polyol and isocyanate), optionally filled with thermally conductive additives
  • Cleaning: Battery modules are cleaned to remove dust, oil, or other contaminants for optimal adhesion
  • Mixing & Dispensing: High-pressure or dynamic mixing systems ensure precise dosing and uniform PUR distribution
  • Encapsulation: The PUR mixture is injected or poured into the battery housing or mold
  • Curing: Rapid curing at ambient or slightly elevated temperatures forms a solid protective layer
  • Inspection: Final inspection for voids or defects ensures quality and reliability
