STN-500A TYPE PVD COATING EQUIPMENT
Equipment£º
• The STN-500A type PVD Coating Equipment has been specially designed for PVD hard-coating, for this purpose the unit is equipped with 2 arc evaporation sources .
• The extreme high rate of ionization in arc evaporation technology provides excellent adhesion properties of the coating to the substrate surface and dense, strong layers.
• For the required golden color the system is provided with Titanium targets and Zirconium targets, also including Titanium-Nitride (TiN) and Zirconium-Nitride (ZrN) process.
• Other colors can be realized by choice of the right target material and appropriate process control.
• The advanced Controlled Arc system with controlled steering of the arc ensures a smooth and homogeneous layer. The controlled Arc-system also provides high coating uniformity and excellent target utilization efficiency.
• The process is running fully automatically by a Programmable Logic Control-unit.
• Chamber, vacuum system, gas flow and controls are chosen of first class design and ensure a reliable, repeatable production with high system availability.
