ESW-50T 5000J Capacitor Energy Storage Hot Press Welding Machine
The ESW-50T is a high-precision 5000J capacitor energy storage hot press welding machine designed for applications requiring accurate temperature control, stable pressure, precise displacement control, and consistent welding quality. With a five-stage heating system, constant-temperature control, and real-time process monitoring, ESW-50T provides a complete solution for precision hot press welding and thermal bonding applications.
The five-stage heating function allows users to set different heating temperatures, heating times, and process stages according to different welding requirements. The constant-temperature control maintains stable heat during the welding process, reducing temperature fluctuation and improving welding consistency. The system is suitable for precision components that require controlled thermal profiles and repeatable welding results.
ESW-50T features an advanced human-machine touch interface with a clear and intuitive operating system. During welding, the screen can display the temperature curve, pressure curve, displacement curve, and corresponding welding data in real time. Operators can monitor the complete welding process directly from the touch screen and quickly identify abnormal changes in temperature, pressure, or displacement.
The welding controller supports monitoring of both average effective values and instantaneous values of temperature, pressure, and displacement. These functions provide more accurate process control and help maintain stable welding quality from one joint to another. By setting appropriate monitoring limits, the system can identify process deviations and provide effective protection for precision welding applications.
The ESW-50T also supports comprehensive pressure monitoring and displacement monitoring. Pressure triggering can be used to start or control specific welding stages, while displacement monitoring can detect changes in the welding process. The system supports displacement melting-depth interruption, allowing the welding process to stop when the preset displacement or melting-depth condition is reached. This provides additional control over welding formation and helps improve process repeatability.
For production traceability, ESW-50T provides a powerful welding data database. The system can store tens of thousands of hot press welding records, including temperature, pressure, displacement, and other process parameters. Stored data can be reviewed for quality analysis and process optimization, while USB export makes it convenient to transfer welding records for production management and quality inspection.
ESW-50T can also connect to an upper-computer welding network and group control system. Multiple welding systems can be managed through network communication, making the equipment suitable for automated production lines and multi-station manufacturing environments. The system can also connect with an MES system to support digital production management, enabling welding data to be collected, analyzed, stored, and traced throughout the manufacturing process.
With 5000J capacitor energy storage, precise five-stage heating, constant-temperature control, temperature monitoring, pressure monitoring, displacement monitoring, database management, USB data export, network group control, and MES connectivity, ESW-50T is designed for manufacturers that require high welding consistency, accurate process control, and intelligent production management.
The ESW-50T combines precision hot press welding, real-time waveform monitoring, intelligent process control, and production data management in one system, providing a reliable solution for demanding thermal welding and hot pressing applications.

Capacitive discharge power supplies are rated in accordance with the amount of energy they store and the welding speed. The energy stored, expressed in watt-seconds (joules), is the product of one-half the capacitance of the capacitor bank and the square of the applied voltage. The energy delivered to the electrodes is considerably less than this value because of losses in the primary and secondary circuits.
