This furnace casts precious metals—gold, silver, platinum, and their alloys—typically using investment (lost-wax) methods. Operating at high temperatures (e.g., 1100°C), it melts the metal and often uses vacuum or centrifugal force to fill molds. The working principle combines a high-temperature melting chamber with a casting mechanism, all designed to handle valuable materials efficiently and with minimal loss. Its purpose is in jewelry making, dental laboratories, and the production of decorative items and high-value industrial components, where material cost demands high yield and precision.
This configuration is suitable when the sample load must fit a 765 x 880 x 765 MM chamber with usable chamber volume of 515 litre, approximate power load of 36.2 kW, rectangular - tall 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.
