Tailored for jewelry making, this digitally controlled furnace performs casting, soldering, annealing, and enamel firing. Operating up to 800°C or more, it offers programmability for different metals and processes. The working principle includes a user-friendly interface with pre-set programs for common tasks, ensuring consistent results crucial for quality jewelry production. Its purpose is to give jewelers and small-scale manufacturers a versatile, precise tool that improves efficiency and reduces scrap from manual temperature guesswork. It's a key piece of equipment in modern jewelry workshops.
This configuration is suitable when the sample load must fit a 750 x 750 x 900 MM chamber with usable chamber volume of 506.3 litre, approximate power load of 35.9 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.

Trutherm manufactures 1200 Degree Celsius (°C) Digital Jewelry Furnace 750 x 750 x 900 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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.
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.
