Used primarily in investment casting (lost-wax process), this furnace combusts the wax or plastic patterns from within the ceramic investment mold. Operating around 750°C, it completely eliminates the pattern material. The working principle involves heating the mold slowly to melt, vaporize, and burn out the wax, leaving a clean, precise cavity, while also curing the mold ceramic to develop strength. Its purpose is a critical preparatory step before pouring molten metal, ensuring the final casting's dimensional accuracy and surface finish. It is indispensable in jewelry making, dental labs, and precision casting foundries.

Trutherm manufactures 800 Degree Celsius (°C) Burn Out Furnace 300 x 300 x 300 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 300 MM chamber with usable chamber volume of 27 litre, approximate power load of 10.9 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.
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.
