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.
This configuration is suitable when the sample load must fit a 400 x 600 x 400 MM chamber with usable chamber volume of 96 litre, approximate power load of 18.3 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.

Trutherm manufactures 1400 Degree Celsius (°C) Jewelry Casting Furnace 400 x 600 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.
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.
