We look forward to having in-depth exchanges with you and exploring more composite material application technologies and solutions.
The communication module shell is sealed to prevent water vapor and dust from entering the inside of the device.
Applied to joint surfaces such as cover plates, flange surfaces and connectors to achieve continuous sealing
Replaces traditional rubber seals and is suitable for automated dispensing production
Meet the long-term sealing and protection requirements of outdoor communication equipment
Excellent waterproof, dustproof and moisture-proof performance
Resistant to high and low temperatures, heat and humidity, and aging, adaptable to complex outdoor environments
Flexible sealing to alleviate assembly tolerances and thermal expansion and contraction stresses
Support automated dispensing to improve production efficiency and consistency
