This furnace is specifically for the controlled, slow cooling of glass products to relieve internal stresses introduced during forming (like blowing or casting). Operating at annealing temperatures (e.g., 550°C), it holds the glass at its annealing point before enacting a carefully programmed cool-down. The working principle uses precise temperature zoning and control to ensure all parts of the glass object cool at the same rate. Its purpose is critical for producing stable, strong glassware that won't crack from internal stress; it is used after any major glass-forming process.
Trutherm manufactures 900 Degree Celsius (900°C) Glass Annealer 600 × 400 × 400 MM Chamber for buyers who search by exact machine type, chamber size and 900°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 600 × 400 × 400 MM chamber with usable chamber volume of 96 litre, approximate power load of 18.300 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.
