Reference definitions for paint-cell terminology used in feasibility reviews, equipment selection, process setup, and production planning.

Best used for

Best used to create shared vocabulary across engineering, purchasing, operations, integrators, and external suppliers.

Use with caution

Definitions do not replace equipment datasheets, coating TDS/SDS documents, or site-specific compliance review.

Evidence basis

Compiled from TD engineering terminology, project scoping language, and equipment-integration workflows.

Orange peel is a surface texture defect resembling orange skin, caused by improper atomization, flash-off, or application conditions. While minor orange peel may be acceptable, severe cases require refinishing.

Why it matters in paint cells

  • •Common defect affecting appearance quality
  • •Often indicates process parameter issues
  • •May be specification-dependent for acceptance

Common causes and solutions

  • •Paint viscosity too high → reduce viscosity or add thinner
  • •Gun distance too far → optimize robot path distance
  • •Atomization pressure too low → increase air pressure
  • •Booth temperature too high → adjust environmental controls
  • •Spray speed too fast → reduce robot TCP velocity
