5 Axis máquina de pintura de radio para el primer PVD
1. Overview
PVD primer application is the critical foundation for successful vacuum metallization. Geetech’s 5 Axis Auto Spray Painting Machine is engineered specifically to apply uniform primer layers that enhance metal adhesion and prevent oxidation during the PVD process.
2. Working Principle
- Substrates are cleaned and loaded onto precision jigs.
- The 5-axis sprayer applies primer with micron-level thickness control.
- UV or thermal curing solidifies the primer without outgassing.
- Pre-treated parts proceed directly to the PVD vacuum chamber.
3. Technical Specifications
| Elemento | Parameter |
|---|---|
| Compatible Primers | UV, PU, NCVM-compatible |
| Thickness Control | ±2 μm |
| Curing Method | UV LED or IR Oven |
| Outgassing Rate | < 1% post-cure |
4. Key Advantages
- Superior adhesion for PVD metal layers
- Uniform primer thickness eliminates metallization defects
- Compatibility with diverse primer chemistries
- Seamless integration into Geetech turnkey PVD lines
5. Quality Control
Primer thickness is measured using eddy current gauges, and adhesion is tested per ASTM D3359. Geetech’s process ensures zero outgassing during vacuum coating, a common cause of PVD failure.
