This furnace is used in the jewelry industry for the lost-wax casting process. Operating around 800°C, it serves two functions: burning out wax patterns from investment molds and/or melting the casting metal. The working principle often involves a combined burnout and melting chamber or two separate units, with centrifugal or vacuum/pressure assist to fill detailed molds. Its purpose is to produce intricate jewelry pieces like rings, pendants, and settings with high dimensional accuracy and fine detail directly from a wax model.

Trutherm manufactures 800 Degree Celsius (°C) Jewellery Casting Furnace 300 x 300 x 450 MM Chamber for buyers who search by exact machine type, chamber size and 800°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 300 x 300 x 450 MM chamber with usable chamber volume of 40.5 litre, approximate power load of 12.9 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.
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.
