This furnace thermally tempers glass by heating it to its softening point (around 650°C) and then rapidly quenching it with high-pressure air blasts. This process puts the surface into compression and the core into tension. The working principle involves a horizontal or vertical chamber where glass sheets are heated uniformly and then moved to a quench section within seconds. Its purpose is to produce safety glass that is 4-5 times stronger than annealed glass and breaks into small, relatively harmless granules. It is mandatory for glass in doors, shower enclosures, and automotive side windows.
Trutherm manufactures 1000 Degree Celsius (°C) Glass Tempering Furnace 500 x 250 x 350 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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 500 x 250 x 350 MM chamber with usable chamber volume of 43.8 litre, approximate power load of 13.3 kW, rectangular - wide 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 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.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
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.
