PVD Vacuum Plating System for Sustainable Coating of Darts

 

The medium frequency magnetron sputtering (MFMS) and multi-arc ion plating (MAIP) composite vacuum coating equipment for dart surface coating is a high-end solution that combines the advantages of two PVD technologies and can simultaneously achieve high adhesion, uniform coating and diversified color effects.

Core advantages of composite equipment
Magnetron sputtering:
The film layer is uniform and fine, suitable for decorative coating on the surface of darts (such as gradient colors, mirror effects).
Can be plated with metals (Cr, Ti) or reactive sputtering compounds (such as CrN, TiAlN).
Multi-arc ion plating:
High ionization rate, strong film adhesion, suitable for darts prone to wear (such as dart tips, grips).
Can be plated with hard coatings (such as TiN, ZrN) to improve wear resistance.

Special optimization of dart coating
Drop-proof design: Multi-arc targets are equipped with electromagnetic filtering devices to reduce the "metal particle" defects on the dart surface.
Color control: The color of the compound is adjusted by the N₂/C₂H₂ ratio (such as TiAlN adjustable purple/blue/gold).
Weight balance: The film thickness tolerance is controlled within ±0.05μm to avoid affecting the center of gravity of dart throwing.

Main Parts of the PVD Coating System(Tailored solution):
a. Vacuum chamber: built-in multi-station rotating frame (dart rotation + planetary revolution) to ensure complex curved surface coverage.
b. Coating system:
① Medium frequency magnetron sputtering source: dual targets (Cr/Ti targets), medium frequency power supply (40kHz) suppresses arc and increases deposition rate.
② Multi-arc evaporation target: 4-6 targets (Ti, Zr, Al, etc.).c. Gas distribution system: precise control of Ar, N₂, C₂H₂ flow to achieve metallic color (TiN), black (CrC) and other colors.
d. Ion cleaning system: Ar ion bombardment cleaning before plating to improve the film-based bonding of darts (especially aluminum alloy dart bodies).
e. Temperature control system
f. PLC controlling system
