Taking full advantage of the plasticity and toughness of metal materials, LandVac adopts a patented lead-free alloy as the sealing material around the vacuum chamber. The welding process is completed in a vacuum state to minimize the additional stress after welding. The quality and service life of the sealing is guaranteed by the online non-destructive flaw detection instrument.
Set reasonable temperature profile, pressure profile and motion velocity profile in the vacuum section according to the gas desorption behavior. Ensure that the vacuum level of each qualified product meets the quality standard through sufficient vacuumizing, online direct vacuum detection and offline indirect measurement and simulation calculation.
LandVac uses the tempered safety glass as its sheet glass sealed with FLAS Flexible Lead-free Alloy Sentry
in the process. The stress balance control technology after sealing completely eliminates the additional stress on the edge of LandVac, allowing LandVac to have its bend strength, wind pressure resistance, and comprehensive safety far superior than those of similar products.
