Power Relay Potting & Curing
Dedicated to the potting and curing process of new energy and industrial relays. Low-temperature precise constant temperature baking realizes bubble-free curing of internal potting glue, closely fitting terminals and shells. It avoids high-temperature damage to internal coils and improves the insulation, waterproof and shock resistance of relays for batch standardized production.
Case 1: Epoxy Potting Drying for New Energy High-Power Relays
Application Scenario:
High-power relays for electric vehicles and charging piles require epoxy insulation potting. Natural curing easily leaves bubbles, causing delamination, water seepage and insulation failure under vibration conditions.
Practical Solution:
Place potted relay shells on the heating platform and bake at a constant 75℃ for 2 hours. The glue cures evenly with automatic defoaming and no residual bubbles. Terminals and shells bond tightly with stable structure, meeting the working condition requirements of new energy equipment for shock resistance, insulation and waterproof performance.
Case 2: Moistureproof Glue Curing for Small Signal Relays
Application Scenario:
Industrial micro signal relays contain enameled coils and precision components, which are easily damaged by high temperature. Low-temperature curing is slow with poor moisture resistance.
Practical Solution:
Adopt precise constant temperature curing at 60℃. The low-temperature process does not damage internal coils and precision components, with glue curing layer by layer for tight fitting. Finished relays have stable insulation resistance and excellent moistureproof, dustproof and anti-oxidation performance for long-term stable operation of industrial precision equipment.
