Traditional methods for sealing busbars use secondary operations to dispense potting material, which is slow and costly, while other methods use rubber O-rings or gaskets that can leak.
ENNOVI-SealTech overcomes these limitations by providing a shrinking method for sealing busbars that prevents the leakage of oil or water coolants while reducing production costs and improving design options. It eliminates the need for extra process steps to dispense filler material required in traditional potting methods, reducing processing time.
Furthermore, ENNOVI-SealTech is significantly lower in cost compared to traditional potting processes without compromising on sealing performance, providing both fill and adhesion for a strong seal during normal injection molding processes.
What Are the Technical Limitations of Traditional Potting?
Traditional busbar sealing relies on slow, secondary operations that dispense potting material into a cavity after the busbar has been over-molded with thermoplastic. These legacy methods are increasingly viewed as bottlenecks because they add significant labor and time to the manufacturing process.
Rigid rubber O-rings or gaskets are also common but carry inherent risks of leaks due to improper seating or material degradation over time.
What Are the Direct Benefits of Shrink-Method Technology?
ENNOVI-SealTech provides a shrinking method for sealing busbars and prevents the leakage of oil or water coolants while reducing production costs and improving design options. It provides both fill and adhesion for a strong seal during normal injection molding processes. This reduces processing time by eliminating the need for extra process steps to dispense filler material required in traditional potting methods.
Furthermore, ENNOVI-SealTech offers cost efficiency, as it is significantly lower in cost as compared to traditional potting processes without compromising on sealing performance.
How Does the Shrink Method Maintain Performance Under Extreme Pressure?
ENNOVI-SealTech provides a shrinking method for sealing busbars, preventing the leakage of oil or water coolants. Furthermore, ENNOVI-SealTech has been tested to achieve no leakage at 7 bar force, even after thermal cycling and aging.
How Does This Technology Enhance Design Flexibility?
Shrink-method technologies are available in versatile options like shrink tubing or tape, allowing them to conform easily to a wide variety of busbar shapes and form factors.
These solutions also offer excellent material compatibility, working seamlessly with various metals and high-performance plastics like PA66, PBT, and PC.
