This furnace is dedicated to melting the precious metals (gold, silver, platinum) used in jewelry making. Operating at high temperatures (e.g., 1100°C for gold), it provides a clean, efficient melt. The working principle typically uses induction heating for its speed and ability to create a stirred vortex for alloy homogeneity, or a compact resistance-heated crucible furnace. Its purpose is to prepare metal for casting ingots, making sheet/ wire, or for direct casting into jewelry molds in a jeweler's workshop. Precision and minimal metal loss are key design goals.
Trutherm manufactures 1400 Degree Celsius (°C) Jewellery Melting Furnace 200 x 200 x 400 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 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.
