Busbar sealing technology

ENNOVI-SealTech provides a shrinking method for sealing busbars, preventing the leakage of oil or water coolants while reducing production costs and improving design options.

Eliminate secondary processes

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. ENNOVI-SealTech overcomes all these limitations.

Cost efficiency

ENNOVI-SealTech 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.

Reduces processing time

Eliminates the need for extra process steps to dispense filler material required in traditional potting methods.

Design flexibility

Easily conforms to a wide range of busbar shapes and form factors.

Excellent sealing performance for a variety of applications

ENNOVI-SealTech has been tested to achieve no leakage at 7 bar force, even after thermal cycling and aging. Options for either shrink tubing or tape accommodate virtually any busbar shape and design parameters. It is also compatible with various types of metals and plastics, including PA66, PBT, PC, and others.

How it works

  1. High-performance plastic
  2. Power interface
  3. ENNOVI-SealTech, our busbar sealing technology

Product applications

ENNOVI-SealTech 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.
