With a wealth of experience in the field of Thermal Batteries and eager to get the very best out of the components of its products, ASB set up its own hermetic seals division in 1996 : ASB Hermetics.

• Specialities : The design, manufacture and marketing of hermetic seals using glass-to-metal sealing technologies.
  
  
• Advantages : Based on its experience in working in extreme environments, the ASB Hermetic division introduced hermetic seals for equally demanding environments, such as aeronautics, space, pyrotechnics and armaments.
  
  
• Production site:The factory at Bourges

The production facilities at ASB Hermetics include the most up to date CAO modeling equipment. Production at ASB Hermetics is carried out in particular by:
