A general furnace for processing precious metals, capable of melting, alloying, and heat treatment. Operating at temperatures around 1100°C, it is built for the high value and specific properties of these metals. The working principle emphasizes precise temperature control, clean heat sources (like induction), and often integrated crucibles and tilt mechanisms. Its purpose is to serve jewelers, refiners, dental labs, and mints, providing a versatile platform for transforming precious metal scrap, granules, or ingots into finished products or standardized forms.

Trutherm manufactures 1400 Degree Celsius (°C) Precious Metal Furnace 900 x 850 x 850 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 900 x 850 x 850 MM chamber with usable chamber volume of 650.3 litre, approximate power load of 39.8 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.
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.
