Focused on industrial furnace R&D, manufacturing and system integration solutions
Jiangsu Suneng Industrial Furnace Co., Ltd. specializes in the R&D, design and manufacturing of electric-resistance and gas-fired industrial heating and heat treatment equipment. Its business covers stand-alone equipment, supporting components and turnkey production lines. The company focuses on heat treatment, forging heating and industrial drying/curing, serving customers in equipment manufacturing, energy, aerospace and defense industries with high-quality equipment and complete process solutions.
Suneng has built a complete furnace portfolio. Batch-type products include pit furnaces, trolley furnaces, car-bottom furnaces, vertical furnaces, box furnaces, bell furnaces, pit-type furnaces, hood furnaces, multi-purpose furnaces, sealed multi-purpose furnaces and sealed box-type multi-purpose furnaces. Continuous products include pusher furnaces, roller hearth furnaces, mesh belt furnaces, chain plate furnaces, chain heating furnaces, walking beam furnaces, rotary hearth furnaces and tunnel furnaces. Vacuum and controlled-atmosphere products include vacuum heat treatment furnaces, protective-atmosphere furnaces, nitrogen-based, endothermic and exothermic atmosphere furnaces, full-hydrogen bell furnaces, bright annealing furnaces and radiant tube furnaces. Dedicated process furnaces include curing furnaces for composite materials, carbon fiber winding, paint and coating processes, sintering furnaces, brazing furnaces, PWHT furnaces, salt bath furnaces, nitrate isothermal furnaces, muffle furnaces, spheroidizing annealing furnaces and high-temperature resistance furnaces.
In process capability, the company covers a broad heat treatment spectrum, including annealing, bright annealing, spheroidizing annealing, vacuum annealing, full-hydrogen annealing, quenching, vacuum quenching, austempering, oil, water and gas quenching, tempering, vacuum tempering, low, medium and high-temperature tempering, normalizing, quenching and tempering, solution treatment, aging, carburizing including low-pressure carburizing, nitriding including ion nitriding and controllable nitriding potential, carbonitriding, nitrocarburizing, boronizing, PWHT, sintering, brazing and resin or composite curing. The equipment supports carbon steel, alloy steel, stainless steel, die steel, aluminum alloy, copper alloy, titanium alloy, superalloy and powder metallurgy parts.
Around its main furnace products, Suneng also provides complete supporting components, including industrial furnace control systems, electrical cabinets, PLC, DCS, temperature control systems, heating elements, silicon carbide rods, molybdenum disilicide rods, resistance strips, radiant tubes, thermocouples and temperature measurement systems, refractory insulation materials, loading and unloading mechanisms, baskets and trays, quenching cooling systems, burners supplied with furnace or line projects, circulation fans, regenerators, furnace doors and covers. The company also has design and construction capability for dedicated heat treatment lines for fasteners, bolts, springs and chains, as well as turnkey lines for carburizing and quenching, bright annealing and forging heating.
The company serves automotive and construction machinery components, gears, bearings, fasteners, springs, molds, cutting tools, forgings, castings, pressure vessels, oil and gas pipes, wind power parts such as main shafts, flanges and gears, nuclear power components, petrochemical equipment, mining machinery, agricultural machinery, aerospace components, aero-engine parts and defense equipment. It also supports steel mills, non-ferrous strip plants and pipe manufacturers with heat treatment equipment for plates, strips, wires, pipes and bars.
Suneng is capable of aligning with and executing domestic and international standards such as AMS 2750, CQI-9, Nadcap, ASME, API, GJB, special equipment manufacturing licensing requirements and GB/T 30822. The company closely follows national strategic directions such as major technical equipment, high-end equipment and industrial mother machines, responds to carbon peaking and carbon neutrality, energy conservation, green manufacturing and intelligent manufacturing transformation, and works with customers to promote high-quality development in industrial heat treatment.
