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.
This configuration is suitable when the sample load must fit a 640 x 900 x 640 MM chamber with usable chamber volume of 368.6 litre, approximate power load of 31.6 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.

Trutherm manufactures 1000 Degree Celsius (°C) Jewellery Casting Furnace 640 x 900 x 640 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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.
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.
