This furnace casts precious metals—gold, silver, platinum, and their alloys—typically using investment (lost-wax) methods. Operating at high temperatures (e.g., 1100°C), it melts the metal and often uses vacuum or centrifugal force to fill molds. The working principle combines a high-temperature melting chamber with a casting mechanism, all designed to handle valuable materials efficiently and with minimal loss. Its purpose is in jewelry making, dental laboratories, and the production of decorative items and high-value industrial components, where material cost demands high yield and precision.
Trutherm manufactures 1100 Degree Celsius (°C) Precious Metal Casting Furnace 330 x 615 x 330 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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 330 x 615 x 330 MM chamber with usable chamber volume of 67 litre, approximate power load of 15.8 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.

Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
