The hot isothermal forging (HIF) line is seamlessly integrated without any interfaces. Our innovative approach is based on the round, multi-vacuum chamber design. In the HIF line chamber, a stable synchronization of temperatures between the workpiece and the dies is maintained throughout the entire forging process. Achieving this balance is possible thanks to the use of vacuum heating furnace technology, which heats both the upper and lower dies and the workpiece.
One notable innovation is the utilization of ceramic blocks for thermal insulation of the tools. These ceramic blocks are highly effective, particularly under the tremendous forging forces. Moreover, the insulation plays a crucial role in protecting the press components from excessive heat. The hydraulic system in the forging press is characterized by tightly controlled strain rates, which enable precise speed and force control. This system is designed with an energy saving concept in mind and boasts a dynamic behavior system for the hydraulic unit, thereby optimizing the overall performance.
Heating furnaces are equipped with multi-zone heating elements, allowing for precise temperature control and uniform heating. To guarantee optimal quality of the final product, a monitoring system is implemented for both the workpiece and the dies. The vacuum unit with integrated mechanical vacuum pumps and filter units achieves the required vacuum level for the HIF process.
The power management system includes the power supply for the furnaces as well as ancillary supply and operating facilities, ensuring seamless operation throughout the forging process.
To oversee and manage the entire HIF line, a control and monitoring system, integrated into a broader digitalization framework, is used. Additionally, the system is supported by our “Management Information Diagnostic Indication System” digital platform, thus enhancing the overall efficiency and reliability of the forging process.
