Driven by the dual demands of lightweight and safety in automobiles, hot forming technology has become a core aspect of enhancing the quality and efficiency of automotive manufacturing. Pruessler has been deeply involved in the processing of automotive hot forming components for many years, maintaining a leading position in the industry thanks to its strong technical foundation and rich experience. Currently, the company has established five major production bases, with an annual production capacity aiming for 7 million units, fully meeting the needs of large-scale production.
At the same time, Pruessler places great importance on the independent research and development of hot forming production lines and equipment, having successfully launched vacuum hot pressing production lines, multi-layer roller hearth furnaces, 3D five-axis laser cutting machines, and six-station laser cutting machines among various advanced hot forming equipment. These self-developed devices not only assist global automotive companies in optimizing production processes and reducing costs but also provide the industry with efficient, high-quality, and sustainable manufacturing solutions, continuously driving technological upgrades and industrial progress in the field of automotive hot forming.
01Vacuum Hot Pressing Production Line
Pruessler has independently developed, designed, and manufactured the world’s first vacuum hot pressing production line. Its core advantage lies in creating a vacuum environment for metal sheets during the heating process, minimizing the oxidation phenomenon that easily occurs during heating. This technology significantly reduces the risk of hydrogen embrittlement and delayed cracking while eliminating the subsequent shot blasting process, thereby enhancing production efficiency and improving part quality. Currently, this technology has been successfully applied in the manufacturing of electro-galvanized hot-formed parts for leading international automotive brands, demonstrating broad market adaptability and technological competitiveness.
02Multi-layer Roller Hearth Furnace
Addressing the issues of traditional heating furnaces being large and having poor scalability, Pruessler has integrated the advantages of box-type heating furnaces and roller hearth furnaces, adopting a multi-layer stacked design to develop the multi-layer roller hearth furnace. It can achieve a larger heating area within the same floor space, significantly saving factory space, making it suitable for production environments with limited land resources, and providing enterprises with a more compact, efficient, and sustainable process option. This not only saves initial investment and operating costs but also offers innovative solutions for large-scale production of hot-stamped parts through high adaptability and flexibility.
033D Five-axis Laser Cutting Machine
Pruessler’s independently developed 3D five-axis laser cutting machine is a rapid cutting device specifically for automotive hot-formed parts, featuring fast cutting, high cutting quality, and safety and stability characteristics, suitable for 24-hour batch production. With five-axis linkage and adaptive zoom technology, it achieves an ultra-high cutting precision of ±0.03mm. Its n×360° infinitely rotating cutting head can complete complex curved surface forming in one go, significantly improving processing efficiency and reducing error accumulation caused by multi-process handling, providing precision machining assurance for structural components of vehicles.
04Six-station Laser Cutting Machine
Pruessler’s independently developed, designed, processed, and produced multi-process cutting equipment. Compared to a single laser cutting machine, the six-station laser cutting machine can decompose the cutting process of formed parts into various stations, each equipped with its own laser cutting mechanism, allowing simultaneous cutting work at each station, resulting in higher cutting efficiency and integration. Its flexible production system, combined with various sensors, robotic arms, and other facilities on the production line, supports one-click switching for multiple models of parts, enhancing capacity while maintaining high adaptability.
Four Core Devices fully embody Pruessler’s strategic concept of driving development through technological self-research. From hardware structure to control systems, from process parameters to system integration, every breakthrough is based on a profound insight into the actual needs of automotive manufacturing. This not only represents the company’s own technological strength but also provides reliable equipment support for the global automotive manufacturing industry.
