Titanium & Medical Battery Seals

At Hermetic Seal Technology (HST), we specialize in crafting custom-designed titanium seals tailored for the unique demands of the healthcare industry. Our expertise lies in manufacturing impeccable glass-to-metal seals specifically engineered for lithium batteries powering essential medical implantable devices including pacemakers, heart defibrillators, drug-delivery systems, portable diagnostic equipment, and pumps.

Here’s why HST’s Titanium & Medical Battery Seals are the preferred choice:

  1. Advanced Manufacturing Processes: Unlike conventional methods, our manufacturing process for medical equipment titanium seals excludes chemical oxide removal processes and carburization. This ensures the preservation of corrosion-resistant capabilities, offering unparalleled reliability for critical medical applications.
  2. Clean Seal Technology: Our production processes yield ready-to-install glass seals without the need for post-machining, streamlining the integration process and minimizing downtime.
  3. Versatile Sealing Solutions: From sealing stainless steel to titanium housings, we offer a wide range of pin and glass combinations to suit diverse application requirements. Electrical feedthrus for critical medical equipment are expertly crafted from materials including molybdenum, stainless steel, and platinum/iridium.
  4. Custom Lithium Corrosion Resistant Glass: In addition to standard materials such as Babal, TA-23, and Cabal 12, we develop our own lithium corrosion-resistant glass materials, ensuring optimal performance and longevity for medical battery seals.
  5. Rigorous Quality Assurance: HST’s commitment to quality is reflected in our 100% leak tests on titanium seals for all types of medical equipment. Our glass-to-metal seals consistently achieve a minimum helium leak rate of 1 x 10-8 cc/sec, guaranteeing reliability and safety for critical medical applications.

Production Capability

We have the ability to handle orders from ten parts to millions of parts.

We can also do sample parts HST can help you with free hermetic seal design and development to insurance you have a reliable and robust glass to metal seal.

Glass-to-Metal Seal Advantages

HST hermetic seals are hermetic (leak – tight) to isolate lithium batteries from external moisture and foreign contaminants to ensure long battery life
HST glass seals can resist extreme temperature and pressure variations while maintaining hermeticity. Our specially formulated glass materials have high corrosion resistance to lithium electrolytes eliminating glass corrosion which reduces shelf life.

Our “Clean-Seal” technology ensures the high quality of glass-to-metal parts that are free from oxidation and chemical residue that can effect welding and material corrosion resistance
