PRESSLER Multi-layer Roller Hearth Heating Furnace, Leading Innovation and Development of Domestic Hot Stamping Production Lines
May 28, 2025 10:11 Jiangsu
With the rapid development of the automotive industry, the requirements for the quality and performance of automotive parts are becoming increasingly higher. Hot forming technology, as an advanced manufacturing process, has been widely used in the automotive industry. The hot forming heating furnace, as the core equipment of the hot forming process, provides reliable guarantee for the production of automotive parts.
There are three main types of heating furnace equipment on the market: roller hearth heating furnace, box heating furnace, and walking beam furnace.
Roller hearth heating furnace is suitable for continuous production of large batches and small varieties. The workpieces are heated evenly, without damage, and with small deformation, but it has high cost, large floor space, and high comprehensive energy consumption;
Box furnace is suitable for small batch and multi-variety production. It has low cost, small floor space, and low comprehensive energy consumption, but it has the problem of low production capacity.
Walking beam furnace is suitable for the production of heavier workpieces, especially indirect hot forming, because indirect hot forming requires the use of trays to carry workpieces to circulate in the furnace. Compared with roller hearth furnaces, walking beam furnaces have higher cost, frequent maintenance, and higher comprehensive energy consumption.
PRESSLER combines the advantages of roller hearth heating furnace and traditional box heating furnace to develop a multi-layer roller hearth heating furnace, which improves the efficiency of the heating furnace and takes into account the thermal energy utilization rate of the heating furnace.
PRESSLER is a complete production solution provider for automotive hot forming parts manufacturing. It has successfully developed multi-layer roller hearth hot pressing production line, laser blanking production line, vacuum hot forming production line, 3D five-axis laser cutting machine and other equipment and supporting software, achieving efficient production of lightweight hot forming parts, ensuring excellent product quality, and adapting to evolving production needs.
