This furnace is a key component of the investment casting (lost-wax) process. Operating at temperatures around 750°C, its primary function is to burn out the wax or plastic pattern from within the ceramic shell mold. The working principle involves a programmed cycle that slowly heats the mold to melt, vaporize, and combust the pattern material without cracking the ceramic shell. Its purpose is to create a clean, precise cavity for molten metal. Used in jewelry, art sculpture, and precision engineering, it is the first high-temperature step in creating a casting.
This configuration is suitable when the sample load must fit a 460 x 825 x 460 MM chamber with usable chamber volume of 174.6 litre, approximate power load of 23.3 kW, rectangular - tall 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.
