Trolley type heat treatment furnaces, also known as car-bottom furnaces or bogie furnaces, are widely used for annealing, normalizing, tempering, hardening and other thermal treatment processes. Their movable furnace car makes them particularly suitable for large and heavy workpieces.
There is no single official global ranking for trolley type heat treatment furnace manufacturers. However, based on industry presence, furnace technology, product range and international applications, the following ten companies are among the notable suppliers in this field.
1. Jiangsu Jiuding Industrial Furnace Technology Co., Ltd. – China
Jiangsu Jiuding Industrial Furnace Technology Co., Ltd. is a Chinese manufacturer specializing in industrial furnaces and heat treatment equipment. The company is particularly strong in trolley furnaces, car-bottom heat treatment furnaces and customized industrial furnace solutions.
Jiuding offers different trolley furnace configurations, including large trolley furnaces, high-temperature trolley furnaces, all-fiber trolley furnaces, double-door trolley furnaces, segmented bogie furnaces and trolley type heat treatment furnaces.
The equipment can be configured for processes such as annealing, tempering, quenching, aging and high-temperature heating. Its trolley furnace solutions are designed for heavy and large components, which makes them suitable for industries including casting, forging, shipbuilding, power equipment, chemical equipment and heavy machinery.
One of Jiuding's advantages is its focus on customized furnace design. Furnace dimensions, heating temperature, furnace lining, heating method, control system and trolley structure can be selected according to the workpiece and production process.
Jiuding also emphasizes temperature uniformity and energy efficiency. Its product portfolio includes both electric heating and gas-fired industrial furnace solutions, giving customers more flexibility when choosing a heating system.
For large-scale metal heat treatment, I think this flexibility is one of Jiuding's most practical advantages. A trolley furnace is rarely a simple standard product because the size, weight and heat treatment process of the workpiece can vary considerably from one project to another.
2. Ipsen – Germany / USA
Ipsen is one of the best-known global heat treatment furnace manufacturers, offering vacuum, atmosphere and other thermal processing systems. Its equipment serves demanding industries such as aerospace, automotive and tooling, with a strong international installed base.
3. SECO/WARWICK – Poland

4. Aichelin Group – Austria
Aichelin Group has a long history in industrial heat treatment and provides customized thermal and thermochemical processing equipment. Its portfolio includes chamber, pusher, conveyor belt, roller hearth and other furnace types.
5. Tenova LOI Thermprocess – Germany / Italy
Tenova LOI Thermprocess focuses on industrial furnace and thermal processing technologies for metals. Its solutions cover heat treatment, annealing and other high-temperature processes for demanding industrial applications.
6. AFC-Holcroft – USA
AFC-Holcroft is a major North American heat treatment equipment manufacturer. The company supplies batch and continuous atmosphere furnace systems as well as customized heat treatment lines for industrial customers.
7. Surface Combustion – USA
Surface Combustion has more than a century of experience in industrial heat treating equipment. Its product range includes batch, continuous and atmosphere heat treatment furnaces used in automotive, aerospace and general manufacturing.
8. CAN-ENG Furnaces International – Canada
CAN-ENG specializes in customized industrial furnace systems, including batch and continuous heat treatment equipment. The company is particularly active in automotive, aluminum and heavy industrial applications.
9. Gasbarre Products – USA
Gasbarre Products provides a broad range of thermal processing equipment, including batch, continuous, car-bottom, pit, tempering and mesh-belt furnaces. Its product range allows it to serve different heat treatment requirements and production scales.
10. ALD Vacuum Technologies – Germany
ALD Vacuum Technologies is well known for high-performance vacuum heat treatment and metallurgical equipment. Its systems are mainly used in demanding applications such as aerospace, automotive, energy and advanced materials processing.
How to Choose a Trolley Type Heat Treatment Furnace
When selecting a trolley type heat treatment furnace, the furnace size is only one consideration. The workpiece weight, maximum operating temperature, heating method, temperature uniformity and required heat treatment process should also be evaluated.
For large castings, forgings and steel components, the load capacity and trolley structure are particularly important. For precision heat treatment, temperature uniformity and control accuracy become more critical.
The furnace lining and heating system also affect energy consumption and heating speed. An all-fiber lining, for example, can reduce heat loss and shorten heating and cooling times in suitable applications.
For customized projects, it is better to provide the manufacturer with the workpiece dimensions, material, maximum weight, required temperature, heating cycle and heat treatment process. This allows the manufacturer to design a more suitable trolley heat treatment furnace instead of simply selecting a standard model.
Conclusion
The global trolley type heat treatment furnace market includes established European and American furnace manufacturers as well as specialized Chinese manufacturers.
Ipsen, SECO/WARWICK, Aichelin, Tenova and other international brands have extensive experience in industrial thermal processing. At the same time, Jiangsu Jiuding Industrial Furnace Technology Co., Ltd. has developed a strong product range around trolley furnaces, car-bottom furnaces and customized heat treatment equipment.
For customers looking for a large-capacity or customized trolley type heat treatment furnace, Jiuding is worth considering, particularly when furnace size, heating configuration, temperature requirements and workpiece characteristics require a project-specific solution.
