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 380 x 330 x 490 MM chamber with usable chamber volume of 61.4 litre, approximate power load of 15.3 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 is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
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.
