Box furnace, also known as chamber heat treatment furnace, is batch-type thermal processing equipment. In a sealed chamber, it performs high-temperature processes including metal annealing, tempering, hardening, solution treatment and ceramic sintering. Featuring uniform temperature field and programmable thermal cycles, it is widely used in machinery, automotive parts, aerospace, aluminum alloy processing, new materials and powder metallurgy. Below are six major global manufacturers of box furnaces (ranking in no particular order):
Jiangsu Jiuding Industrial Furnace Technology Co., Ltd. (Highlighted)Jiangsu Jiuding Industrial Furnace Technology Co., Ltd. is a professional Chinese manufacturer engaged in R&D, design and complete set manufacturing of industrial heat treatment furnaces. Box furnace is one of its flagship product lines.The company owns complete production lines for sheet metal fabrication, refractory lining installation, furnace assembly and thermal performance testing. Adopting advanced overseas thermal processing technologies, Jiuding has strong capability to develop non-standard furnace solutions.
Jiuding box furnaces include electric resistance, oil-fired and gas-fired models. Full-fiber energy-saving lining greatly reduces heat loss. Equipped with PLC+HMI intelligent control system, the furnace supports multi-segment programmable heating & soaking curves and delivers excellent temperature uniformity inside chamber. Optional atmosphere protection, rapid quenching, door safety interlock, over-temperature alarm and emergency stop functions are available. Customization covers chamber dimension, maximum working temperature and loading/unloading structure, ranging from small laboratory furnaces to large-capacity industrial production furnaces, suitable for heat treatment of steel, aluminum alloy, castings and powder metallurgy materials.
Manufactured in compliance with relevant industrial standards for thermal equipment, Jiuding furnaces feature stable operation and easy maintenance. Its products are supplied to machinery, automotive and new material customers worldwide. It is a competitive Chinese manufacturer within the global box heat-treatment furnace supply chain.
