INTRODUCTION

Are your connectors on the verge of failure due to "micro-leaks" in high vacuums or deep-sea environments?

Standard O-rings and potting compounds have their limits when facing extreme conditions—adhesives age, O-rings deform under pressure, and organic materials suffer from "outgassing" at high temperatures. Are you struggling with pressure loss in aerospace vacuum environments? Or perhaps your sensors are suffering irreversible chemical damage from alternating exposure to strong hydrochloric acid and seawater?


When leakage equates to catastrophic system failure, you need a physical, permanent, and absolute isolation solution.

Technical Core: Inorganic Fusion Defining Absolute 18GHz Stability

CHIN NAN’s "Glass-to-Metal Seal (Glass Bead)" technology melts and fuses glass and metal components within a high-temperature furnace. This is not simple adhesive bonding; it is a molecular-level union:

  • True Hermetic and Liquid-Tight Seal: As an inorganic material, glass is completely non-porous and never ages. It achieves the highest level of hermetic performance, ensuring that under extreme pressure differentials or high vacuums, gases and liquids (including seawater and strong acids) absolutely cannot penetrate from the outside or leak from the inside.
  • Peak Electrical Performance & Thermal Matching: We precisely calculate the coefficient of thermal expansion (CTE) for both the glass and the metal to ensure the structure remains seamlessly tight under severe temperature swings from -65°C to 165°C. Its low dielectric properties allow signals to maintain excellent impedance matching and low return loss during 18GHz high-frequency transmission.
  • Superior Mechanical Strength: The sintered glass bead possesses extreme compressive strength, supporting the center pin and maintaining precise geometric positioning even under immense external impacts or high-G vibrations.

Practical Applications: From Deep-Sea Exploration to Polar Research

This technology is tailor-made for Pro-level missions where there is zero tolerance for maintenance or failure:

  • Aerospace & Satellite Equipment: Prevents gas leakage from electronic compartments in the high vacuum of outer space and totally eliminates material outgassing that could contaminate precision optical components.
  • Deep-Sea Exploration & Pressure Chambers: Withstands immense seawater pressure at depths of thousands of meters, providing bidirectional insulation and sealing, both internally and externally.
  • Petrochemical & Semiconductor Manufacturing: Facing highly corrosive gases or liquids (like hydrochloric acid or etchants), the glass-sintered layer offers unparalleled chemical defense, ensuring the long-term operation of 18GHz high-frequency sensors.
