Compact Robotic Painting Workstation for Small Parts
A small parts manufacturer deployed a compact robotic painting workstation to handle small batch, multi-type production with frequent changeover requirements.
Background
A manufacturer producing small plastic parts — including connectors, earphone shells, and power bank housings — needed a flexible painting solution. Their production pattern was characterized by small batches (500–2,000 pcs per order), many product types (50+ SKUs), and frequent changeover (sometimes 3–4 times per day). Their manual painting setup could not keep up with this variability, and quality was inconsistent across different part geometries.
Customer Pain Points
Small batch production with 50+ product types requiring frequent changeover
Manual painters struggled to maintain quality across different part geometries
Long setup times between products reducing effective production time
Small parts difficult to handle manually — high drop rate and coating defects
Operator training expensive — new painters needed 2–3 months to reach acceptable quality
Limited floor space for a full production line
Proposed Solution
We designed a compact robotic painting workstation specifically for small parts manufacturing. The workstation featured a small footprint, flexible fixtures that could accommodate different part types, and quick-change recipe management. The system was designed for easy operator training — workers could learn to operate it within days rather than months.
System Configuration
1x 6-axis compact painting robot
Quick-change fixture system with modular part holders
Integrated spray booth with compact ventilation design
Recipe management with one-touch product changeover
Automatic spray gun with fine atomization for small parts
Turntable fixture for multi-angle coverage
Touch-screen HMI with visual recipe selection
Ionizing air system for static elimination
Project Results
Improved flexibility — system handles 50+ product types without hardware changes
Changeover time reduced from 30+ minutes to under 5 minutes
Easier operator training — new operators productive within 1 week
Coating quality consistent across all part types and geometries
Compact footprint — fits within existing production area
Paint savings of approximately 25% compared to manual spraying
Suitable Applications
Small plastic parts: connectors, earphone shells, power banks
Electronic device housings and enclosures
Small batch, high-mix production environments
Factories with limited floor space for automation
