Electronic vacuum coating machine RT1600-NCVM

for plastic parts

NCVM is short name of Non Conductive Vacuum Metallizing, which is used for plastic parts plated which are coated by vacuum deposition technology. This techniques uses each other discontinuous features, to generate a final appearance of the metallic finish and doesn’t affect the effect of the wireless communication transmission. NCVM Applications: mostly for electronic product industries, communication devices. Mobile phone, telephone, smart phone, GPS satellite navigation, blue tooth headset, computer etc. Properties With resistance thermal evaporation technology to evaporate high pure Tin (Sn) metals and then condense on the plastic work pieces. The controlled thickness allows a none-conductive thin film on electronic parts. .Sn material purity: over 99.99% .Tin film thickness: around 30nm .With high resistance value and excellent metallic finish. 2.1 The main factors affecting the effect of coatings are Vacuum Pressure Vacuum Deposition chamber size Evaporation materials quantity and quality Quality and quantity of coating materials Evaporation sources model selection Distance between product and evaporation source Spaces between evaporation sources Evaporating current working value and distribution Evaporation time Rack and planetary axis rotation speed etc. 2.2 For vertical orientation machines, the above factors can be controlled by the coating parameters setting, which is a guarantee of high coatings yield. 2.3 To improve the uniformity problem effectively, the evaporation sources (tungsten wires) are specially designed. Which are distributed in a multi-level from high to low, enable the evaporated and condensed metal vapors in a 360 degree space.
