This is a general-purpose furnace found in jewelry workshops, capable of performing multiple tasks: melting, casting, soldering, annealing, and enamel firing. Operating temperatures typically range to 800°C or higher for melting. The working principle emphasizes versatility, safety, and ease of use, often with programmable settings for different metals and processes. Its purpose is to serve as the primary thermal processing station for a jeweler, consolidating several tools into one and improving workflow efficiency in creating and repairing jewelry items.
Trutherm manufactures 1400 Degree Celsius (°C) Jewelry Furnace 640 x 375 x 375 MM Chamber for buyers who search by exact machine type, chamber size and 1400°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 640 x 375 x 375 MM chamber with usable chamber volume of 90 litre, approximate power load of 17.8 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.

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.
