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 1000 Degree Celsius (°C) Jewelry Casting Furnace 830 x 830 x 900 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.
This configuration is suitable when the sample load must fit a 830 x 830 x 900 MM chamber with usable chamber volume of 620 litre, approximate power load of 39 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.

Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
