Scope

Engineering guidance for robotic spray painting, paint booths, paint supply systems, and production-scope decisions.

Best used for

Best used for early-stage feasibility checks, vendor comparison, scope definition, and internal project alignment.

Use with caution

Final specifications still depend on coating chemistry, part family, takt, utilities, site layout, local code, and EHS review.

Evidence basis

Based on TD engineering team experience, recurring project delivery patterns, and equipment-integration practice.

Steel enclosure line moving from manual spray to robotic finishing

The manufacturer runs cabinets, frames, and brackets in medium volume. Manual spray quality varies by shift, and skilled-painter availability is becoming a bottleneck.

Challenges

  • Part size varies enough that fixture strategy and robot envelope need to be defined carefully.
  • The business wants paint savings and quality stability, but also needs quick response to mixed-model schedules.
  • Existing booth and handling methods were designed around manual flexibility, not robotic repeatability.

Evaluation steps

  • Group parts into families by geometry, finish requirement, and handling method.
  • Check booth and paint-supply limits before locking robot scope.
  • Use the system-level solution scope to define what must change beyond the robot itself.

Healthy outcome signals

  • A good scenario outcome shows fewer quality swings, lower labor dependence, and a realistic automation boundary for mixed-model work.
  • If part families cannot be grouped sensibly, the project may need partial automation instead of a single universal cell.
