UV Primer Spray and Vacuum Metallizing Line Solution
This solution focuses on the critical interface between the substrate and the metal layer. It executes plasma or flame surface treatment, 5-axis UV primer application, LED-UV curing, and then vacuum metallization. Without this primer, PVD films will delaminate, especially on challenging plastics like ABS and PP. The primer seals micro-porosities and provides a chemically compatible surface for metal adhesion.
5 Critical Considerations for Your Solution:
1. Primer Viscosity: Atomization settings affect surface smoothness.
2. Cure Energy: Cross-link sufficiently without over-baking plastics.
3. Primer Chemistry: Must be compatible with PVD target materials.
4. IR Preheating: Reduce thermal stress during curing (50–60°C).
5. Booth Filtration: Prevent particulate contamination of the primer layer.
Geetech (Dongguan Geetech Electrical-Mechanical Equipment Co., Ltd.) calibrates primer application parameters using laser profilometry to ensure a flawless foundation. Our integrated lines feature shared conveyors, eliminating manual part transfers that can compromise primer integrity before metallization.
