1. Balancing High-Speed Feeding with Dynamic Stability In the mass production of automotive condensers and intercoolers, fin-forming speed is the primary driver of line throughput. The WDL-60-P system integrates the HDV-E600-4T3.7B high-performance frequency inverter, enabling a stable feeding speed of 40m/min. This power configuration not only boosts the cut-off frequency to 60 times/min but also ensures the consistency of fin geometry through precise tension compensation. This prevents the common issue of wave-summit stretching distortion often seen in conventional equipment during high-speed runs. 2. Improving Assembly Quality via "Zero-Error" Cutting Process Heat exchanger core stacking requires extreme consistency in fin length. Leveraging its centralized PLC control system, the machine achieves a physical cutting accuracy of ±0mm. The technical core lies in the system's ability to precisely trigger the cutting mechanism at the fin summit. This "zero-error" performance eliminates cumulative tolerances during continuous processing, ensuring that fins fit perfectly with cold plates or flat tubes prior to vacuum brazing, fundamentally securing the sealing and thermal efficiency of the heat exchanger. 3. Modular Scalability and Automated Synergy To accommodate diverse specifications from condensers to industrial oil radiators, the WDL-60-P features a replaceable forming device design. All operational logic—from production counting to emergency shutdown protection—is managed within a closed-loop automated system. The reserved interface allows for seamless connection to fin collection units, which, combined with the compact footprint of 4900×760×1900 mm, optimizes floor space utilization. This parametric-managed flexible production line provides heat exchanger manufacturers with superior process agility.

1. Ultimate Vacuum Evacuation Logic: Eliminating "Electrical Weak Points" within Windings When processing large 2000mm stators or high-voltage transformer coils, the density of the insulation structure directly impacts the partial discharge performance. The VPI2000 system is equipped with a two-stage high-efficiency vacuum unit consisting of rotary vane and Roots pumps, achieving an ultimate vacuum degree of ≤100Pa. This extreme low-pressure environment rapidly exhausts all air and residual moisture within the Φ2000 × 2000mm impregnation tank and deep within the coil windings. Through this parametric vacuum treatment, the equipment eliminates the possibility of bubble formation at a physical level, creating ideal conditions for subsequent unobstructed resin saturation. 2. Pressure-Compensated Penetration: Achieving Dense Encapsulation under 1.0MPa Load Gravity or atmospheric dipping alone cannot meet the insulation challenges of tight windings. After vacuum filling, the VPI2000 applies a design pressure of up to 1.0MPa via its pressure vessel system designed according to national standards. Under this continuous and stable pressure load, the insulating resin is forced into the deepest micropores and crevices of the coils, reaching a superior fill rate. This process not only elevates the mechanical strength of the component to a new dimension but also significantly enhances the moisture, mold, and pollution resistance of the motor, ensuring a stable insulation class even in extreme industrial environments. 3. Digital Process Monitoring and Thermal Stability To safeguard the chemical activity of large volumes of resin, the VPI2000 integrates digital thermal management logic into its storage system. The inner chamber is fabricated from 1.5mm stainless steel, paired with an advanced refrigeration unit and PT100 temperature sensors to ensure the resin remains within its optimal process temperature range. All operational parameters—including the ≤100Pa vacuum curve and pressure fluctuations—are recorded in real-time by the PLC automated control system and monitored via a 21-inch LCD screen. This high level of automation reduces uncertainties from manual intervention, providing motor service centers and manufacturing hubs with traceable and verifiable insulation quality assurance.
