This kiln is designed for the specific task of burning out organic materials from ceramic molds or castings, common in art foundries and jewelry making. Operating at 750°C, it performs a dual function: removing the pattern and firing the mold. The working principle involves careful programming of temperature increases to avoid thermal shock to the ceramic shell while ensuring complete organic removal. Its purpose is to create a strong, empty mold ready to receive molten metal in the lost-wax casting process. It is a specialized piece of equipment critical for producing detailed metal artworks and precision components.
Trutherm manufactures 800 Degree Celsius (°C) Burnout Kiln 300 x 300 x 450 MM Chamber for buyers who search by exact machine type, chamber size and 800°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 300 x 300 x 450 MM chamber with usable chamber volume of 40.5 litre, approximate power load of 12.9 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.

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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
