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 245 x 235 x 400 MM chamber with usable chamber volume of 23 litre, approximate power load of 10.2 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.
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.
