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.

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.
