This furnace performs various thermal processes on glass, including annealing, tempering (thermal strengthening), and bending. Operating at temperatures like 650°C, it heats the glass uniformly to a specific point before the next step (like quenching for tempering). The working principle depends on the process: for tempering, it involves rapid, uniform air quenching; for annealing, controlled slow cooling. Its purpose is to enhance the mechanical and safety properties of glass for applications ranging from automobile windshields and building windows to smartphone screens.

Trutherm manufactures 700 Degree Celsius (°C) Glass Heat Treatment Furnace 450 x 450 x 450 MM Chamber for buyers who search by exact machine type, chamber size and 700°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 450 x 450 x 450 MM chamber with usable chamber volume of 91.1 litre, approximate power load of 17.9 kW, square chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
