Semi-Automatic Lifting Immersion Electrophoretic Coating Production Line
LENDEER's semi-automatic e-coating line uses a motor-driven chain and PLC control to lift and index workpiece hangers through pretreatment, electrophoretic coating and rinsing tanks. It is engineered for medium-volume metal parts that require repeatable process timing without the investment and floor-space demand of a fully automatic conveyor system. To compare other automation layouts, view our electrophoretic coating line systems.

Unlike fully automatic conveyor lines, the semi-automatic lifting line does not require a continuous overhead conveyor structure, gantry rail system, or large-scale civil installation. Workpiece loading and unloading are performed manually by operators at designated stations, making the line accessible to facilities that need consistent, controlled process timing but cannot justify or do not yet require the
The fixed-cycle PLC control ensures that every workpiece receives identical immersion times in every tank regardless of operator experience or shift variation. This process discipline is the defining quality advantage of the semi-automatic line over purely manual operations: bath chemistry, voltage, temperature, and time are all controlled, resulting in consistent film thickness, consistent phosphate weight, and consistent corrosion resistance â?? batch after batch. LEDE supplies the complete system as a turnkey package, engineered and commissioned to your exact production requirements.
