The core difference between the three options is not "who is more advanced", but whether the space coverage, gun posture, gun range control, tempo and product switching required for the workpiece can be completed at the lowest lifecycle cost. The three-dimensional large-stroke reciprocating machine is suitable for large-size workpieces with regular trajectories, few attitude changes, and stable batches; the multi-axis servo sliding table is suitable for scenarios that require X/Y/Z linkage, local angle compensation, and modular expansion, but does not yet require complete six-axis attitude freedom; the industrial coating robot is suitable for workpieces with complex curved surfaces, multiple deep cavities, continuous changes in gun attitude, frequent product switching, and high quality requirements. ROI can not only compare the purchase price, but also include equipment, integration, spray room transformation, software, maintenance, shutdown, labor, paint utilization, yield, beat and flexible income in the TCO model for 3—5 years or the agreed cycle of the project.
