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.
This configuration is suitable when the sample load must fit a 420 x 420 x 800 MM chamber with usable chamber volume of 141.1 litre, approximate power load of 21.4 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.

Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
