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.

Surface-energy and adhesion terms that support flame treatment queries.

Surface energy

A measure of how easily a liquid coating can wet and bond to the substrate surface.

Why it matters: Flame treatment exists mainly to raise surface energy on difficult plastics so primers and topcoats can bond reliably.

Adhesion

The bond strength between the coating film and the substrate.

Why it matters: Most flame-treatment projects are judged by adhesion-test results rather than by appearance alone.

Flash-off Time

The time allowed for solvent or water to leave the coating before the next process step.

Why it matters: In integrated lines, treatment timing and flash-off timing both influence whether the final film remains stable and defect-free.

Orange Peel

A textured finish defect caused by poor flow or atomization behavior.

Why it matters: Surface activation issues and coating-parameter issues often get confused; this term helps separate adhesion failures from finish defects.
