Functionally identical to the Jewellery Casting Furnace, this furnace is central to the investment casting process in jewelry manufacturing. Operating at around 800°C for burnout and higher for melting, it enables artisans to reproduce complex wax models in metal. The working principle has evolved to include digital controls and integrated vacuum/ pressure systems to ensure flawless mold filling. Its purpose is to bridge the gap between design and finished piece, allowing for the production of both one-of-a-kind items and small batches with consistent quality.
Trutherm manufactures 800 Degree Celsius (800°C) Jewelry Casting Furnace 200 x 200 x 400 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 200 x 200 x 400 MM chamber with usable chamber volume of 16 litre, approximate power load of 8.8 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.

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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
