ENNOVI-SealTech provides a shrinking method for sealing busbars that is compatible with various types of metals and plastics, including PA66, PBT, PC, and others. It is an ideal solution for any application that requires liquid coolant or lubricant on one side and dry electrical connections on the other.
It can be used with either busbars or other interconnects to accommodate applications such as motors, inverters, or oil pump interfaces. This technology prevents the leakage of oil or water coolants while reducing production costs and improving design options.
Which Plastic Materials Offer Compatibility with Shrink-Method Technology?
ENNOVI-SealTech uses a shrink-based busbar sealing approach that works with a wide range of metals and plastics, including PA66, PBT, PC, and other compatible materials. Options for either shrink tubing or tape accommodate virtually any busbar shape and design parameters. It is an ideal solution for any application that requires liquid coolant or lubricant on one side and dry electrical connections on the other, and can be used with either busbars or other interconnects to accommodate applications such as motors, inverters, or oil pump interfaces.
What are the Drawbacks of Traditional Potting and Gasket Methods?
Traditional methods for sealing busbars use secondary operations to dispense potting material into a cavity around the busbar after it has been over-molded with thermoplastic. Other methods use rubber O-rings or gaskets around the busbar. Secondary dispensing is slow and costly, while rubber gaskets can leak.
How does Integrated Shrink-Method Sealing Optimize Production?
ENNOVI-SealTech provides a shrinking method for sealing busbars that is significantly lower in cost as compared to traditional potting processes without compromising on sealing performance. It provides both fill and adhesion for a strong seal during normal injection molding processes, which reduces processing time by eliminating the need for extra process steps to dispense filler material required in traditional potting methods.
Shrink tubing or tape options can adapt to many busbar shapes and design requirements. They can also be applied to busbars or other interconnects used in motors, inverters, oil pump interfaces, and similar applications.
Seal the Deal on Drivetrain Reliability
Utilizing advanced shrink-method sealing with compatible materials like PA66, PBT, and PC ensures a robust and cost-effective interface for electric vehicles. These innovations allow engineers to achieve consistent, leak-free reliability while simultaneously streamlining mass production workflows. By removing slow secondary processes and replacing prone mechanical gaskets, manufacturers can deliver higher-quality drive modules at a lower total system cost.
