A furnace dedicated to the first step of lost-wax casting: removing the wax pattern from the investment mold. Operating at temperatures around 750°C, it uses a controlled cycle to melt, vaporize, and combust the wax. The working principle involves a slow temperature ramp to prevent mold cracks from rapidly expanding wax, and good ventilation to carry away wax vapors. Its purpose is critical in jewelry, dental, and precision investment casting foundries to create a clean, precise cavity in the ceramic shell before it is filled with molten metal.
This configuration is suitable when the sample load must fit a 680 x 400 x 400 MM chamber with usable chamber volume of 108.8 litre, approximate power load of 19.2 kW, rectangular - wide 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.

Trutherm manufactures 1200 Degree Celsius (°C) Wax Burnout Furnace 680 x 400 x 400 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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.
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.
