  • LandGlass' research and development history in the field of variable curvature glass tempering started several years ago when the straightness of the straight edge of bent glass products' was yet a technical challenge.

    Since then, LandGlass had tried three different kinds of bending technologies. Finally in 2011, after the combination of intelligent servo control systems and innovative flexible bending mechanism, LandGlass made a breakthrough in the development of Variable Curvature Glass Tempering Furnaces. The newly developed bending technology not only provided a better final product but it also improved reliability and extended the life of the equipment.

    In 2012 LandGlass showed the industry its "J Shape" tempered glass products. In 2013 LandGlass introduced the "U Shape" Glass Tempering Furnace. equipped with JetConvectionTM heating technology, capable of tempering off-line Low-E glass and other challenging bent glasses.

    JetConvectionTM Convection heating plays an important role during glass heating. Air is heated in the JetConvection chamber inside the heating furnace and is blown onto the glass surfaces. Air is then recirculated and recirculated by the convection blowers into the JetConvection chamber. LandGlass Jetconvection technology enhances the quality of the final product and increases productivity by ensuring an even heating, while minimizing production costs.

    LD-D JetConvection PlusTM Variable Curvature Glass Tempering Furnaces are mainly used to bend and temper variable curvature glass. They are demanded to produce the glass for commercial refrigerators, food showcases, and high-class buses. The intelligent servo control system and flexible arching mechanism are applied to the furnace, which can process various kinds of high-quality variable curvature glasses through the innovative process and furnace layout. In addition, the furnace can process various kinds of coated glass and clear glass through the forced JetConvection heating technology.
  • 1. The innovative arc forming technique and the flexible bending mechanism ensure the flexibility and fast adoption of the curvature. The high precision bending mechanism ensures the accuracy and stability of arc forming.

    2. There is no movement in the bending mechanism during the bending process, which ensures the glass accuracy and repeatability, reducing daily maintenance.

    3. Glass that can be tempered includes: on-line and off-line Low-E (E=0.02) glass, extra ultra clear glass, screen printed glass, pattern glass, tinted glass, clear glass, etc.
