Vacuum Coating UV Curing Chamber
Definition & Positioning
The Vacuum Coating UV Curing Chamber is a critical UV curing station located immediately after the PVD vacuum coating chamber. It performs second-level UV curing for primer, middle coat, and topcoat, without participating in the physical vapor deposition process itself.
Working Principle
Utilizing 365/395 nm mercury lamps or UV-LED light sources, photoinitiators absorb UV photons to generate free radicals, enabling the instantaneous cross-linking of acrylic coatings into a solid film. With a typical energy range of 500–2000 mJ/cm², the system allows precise matching of conveyor speed and light intensity for optimal curing.
Structural Composition
The unit features a stainless steel/aluminum alloy chamber with high-reflectivity mirrors, a UV lamp array (air/water-cooled), mesh belt or roller conveyors, an integrated heat exhaust and workpiece cooling section, and a PLC-controlled power regulation system with safety door interlocks.
Core Advantages
It replaces traditional lengthy baking ovens with low-temperature curing that prevents plastic deformation. The resulting film offers high hardness, scratch resistance, and alcohol resistance, effectively sealing the PVD metal layer against oxidation while maintaining ultra-low VOC emissions for strict environmental compliance.
Typical Applications
Ideal for metallized plastic components including mobile phone/laptop housings, automotive lamp bezels, cosmetic caps, eyeglass frames, bathroom hardware, and appliance trim.
