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.

Trutherm manufactures 1000 Degree Celsius (°C) Lost Wax Casting Furnace 225 x 225 x 450 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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 225 x 225 x 450 MM chamber with usable chamber volume of 22.8 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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
