We are market leaders in the provision of specialized laser hermetic sealing. Laser hermetic sealing is another fusion welding process that employs laser welding technology. Medical, semiconductor, defense, aerospace, transportation, power generation, and construction are some of the common industries that require laser hermetic sealing process for products.
Parts are generally laser sealed after vacuum baking to less than 1 ppm of oxygen and moisture, which improves the performance characteristics of parts compared to that of any other conventional epoxy, solder and mechanical seals. Our welding processes use minimal heat so that sensitive, precision components are protected from thermal damage likely to be caused by methods using higher temperatures.
|High reliability||Designed for long term performance in the harshest and most demanding environments.|
|No Thermal Damage||Minimal heat produced, protecting precision components from destructive high temperatures found with solder seals.|
|Dry and Oxygen Free||After a vacuum bake, parts are laser sealed in less than 1 ppm (parts per million) of oxygen and moisture providing a level of performance that conventional epoxy, solder and mechanical seals cannot fulfill.|
Our laser hermetic sealing process complies with ISO 9001:2008 standards. We follow the military standards MIL-PRF-38534E and MIL-STD-883 in our laser sealing and laser detection processes. We also own an aerospace quality system AC7004 certification from Nadcap.

Our CNC-controlled laser glovebox workstations are capable of monitoring and controlling an inert atmosphere (comprising gases such as Argon, Helium or Nitrogen) with moisture and oxygen levels maintained below 1 ppm. Standard real time batch reports prove this. Our laser hermetic sealing equipment portfolio comprises ovens that operate at temperatures of about 200 degrees centigrade and less than 200 microns vacuum. Fluorinet-based gross leak detection up to 10-3 cc.he/sec and mass-spectrometer helium fine leak detection of up to 10-11 cc/he sec are offered as part of our laser hermetic sealing services to ensure that all your diverse sealing needs are fulfilled.
