About Us > Intelligent Manufacturing

① Machining: Made with full-length electromagnetic chucks to control the thermal deformation and residual stress during the machining process to ensure the minimal deformation of bipolar plates

② Welding: Automatic double-sided laser welding of the bumpy plate and the frame, pressing, fitting, shaping, and 100% detection of kerosene leakage

③ Electroplating: Acid etching activation process for the firmer bonding of bipolar plates, and constant current nickel plating process for even and stable coating

① Hydraulic screw jacking structure makes it possible to pass through the screw hole on the upper end plate of the electrolyzer from bottom to top for better assembly efficiency

② 4-in-1point cylinder-type hydraulic automatic lifting enables adjustable speed and stable lifting for the assembly of 3000 Nm³/h and below products

③ European imported single beam motor with double speed modes and double control options for frequency conversion between large and small volumes enables safe and stable stacking of bipolar plates and end plates

④ Bipolar plates are assembled under three-hole positioning and tested with five-line laser leveler + lead hammer line drop to ensure proper vertical deviation

① Drawing, netting, spraying, activation, and laser cutting for products with the large specific surface area, stable size, high current density

② The automatic laser welding technology enables no welding slag splash, small arc damage, high welding efficiency, exquisite welding formation

③ FANUC robotics + laser seam tracking technology for deviation enables automatic sorting and welding of electrode mesh, where the welding is efficiently done in a more stable and uniform manner

Prefabrication: Design a highly flexible integrated pipe fixture table to prefabricate pressure pipes with high efficiency, small welding deformation and high precision.

Welding: Special automatic welding machine for pressure pipelines, the welding efficiency is 3 times that of manual work, the production consistency is high, the welds are beautifully formed, and the first pass rate of flaw detection reaches more than 98%.

Traceability: Each weld is assigned a unique welding number, and the welding process information is recorded through the traceability label to trace the entire welding quality process.

Testing: The welds of the pipelines in the separation and purification system are 100% pickled and passivated, and the welds are radiographed in strict accordance with the requirements of GB50184.
