Muffle furnace manufacturers specialize in designing and producing high-temperature furnaces used for heat treatments, material testing, and laboratory applications. These furnaces are equipped with an insulated chamber that ensures uniform temperature distribution and prevents contamination from external elements. Muffle furnaces are commonly used in industries such as metallurgy, ceramics, and research labs, where precise and controlled heating is essential for various processes, including ash testing, sintering, and metal annealing.
