How to Choose the Right Hermetic Seals
Hermetic seals refer to the state of being air or gas tight, to prevent the escape of a liquid or gas. In the early days of distillation, the process of creating an airtight seal was highly valued and the secret of the seal was a closely guarded secret. Today, hermetic seals are widely used in many industries including aerospace, defense, nuclear, geophysical, medial and oil and gas exploration because they can stand up to the pressures and protect from corrosion and contamination.
Two common types of hermetic seals are Glass-to-metal seals and Ceramic-to-metal Seals.
Glass-to-metal seals provide a very effective sealing hermetically during severe temperature changes or sudden changes in pressure or humidity. Glass-to-metal seals are used very common due to its cost-effective and wide variety of uses.
Ceramic-to-metal seals require more labor -intensive and more time to manufacture than glass-to-metal seals. They are more costly; however, applications of ceramic seals are recommended to some industries due to their exceptional resistance to mechanical and thermal shock. They are widely used in aerospace, medical implant devices and other fields because these offer more durable hermetic seal and better electrical insulation than glass-to-metal seals.
When comes to hermetic seals manufacturers, be sure to choose one that can offer the broadest line of hermetic products and services as well as is experience in a range of applications. Since each industry has their specific needs and require customized hermetic products, choose a manufacturer that can meet your custom-designed and custom-made requirements. Moreover, they ought to have experienced practices and strong quality assurances in order to offer you the best hermetic products.
