This furnace is used in dental laboratories to cast dental restorations like crowns, bridges, and partial dentures using the lost-wax technique. Operating around 900°C, it melts dental alloys (often gold, cobalt-chrome, or silver-based). The working principle involves a high-frequency induction or resistance melting system in a crucible, often with a vacuum/ pressure assist to force metal into the detailed mold. Its purpose is to produce precise, high-quality metal frameworks that fit a patient's anatomy perfectly. It is a core instrument in commercial and in-house dental labs worldwide.
This configuration is suitable when the sample load must fit a 885 x 850 x 850 MM chamber with usable chamber volume of 639.4 litre, approximate power load of 39.5 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.

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.
