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.

Key terms including DFT, transfer efficiency, overspray, and 2K paint.

Dry Film Thickness

The cured coating thickness measured on the part after drying or curing.

Open related page

Why it matters: Metal finishing projects often live or die on whether DFT is consistent enough for protection and appearance requirements.

Transfer Efficiency

The percentage of sprayed paint that lands on the part instead of becoming waste.

Open related page

Why it matters: It is one of the clearest ways to explain ROI for robotic finishing versus manual spray.

Overspray

Material that misses the part and loads the booth environment.

Open related page

Why it matters: Overspray drives material loss, booth maintenance, and many quality-stability discussions on metal finishing lines.

2K Paint

A two-component coating system that mixes base and activator before use.

Open related page

Why it matters: Many industrial metal finishing lines use 2K systems, so mixing, pot life, and cleanup logic become part of automation planning.
