NCVM uses metal and insulating compound coatings to obtain the final appearance with metal texture without affecting the effect of wireless communication transmission by utilizing the discontinuity of each other. First of all, it is necessary to achieve non-conductivity to meet the normal use of wireless communication products; secondly, it is necessary to ensure the important appearance requirements of "metal texture"; finally, through the combination of UV coating and coating layer, the product's physical properties and weather resistance are guaranteed to meet customer needs. NCVM can be applied to all kinds of plastic materials, such as PC, PC+ABS, ABS, PMMA, NYLON, engineering plastics, etc. It is more in line with the green environmental protection requirements of the manufacturing process, and is an alternative technology for non-chromium plated products. It is suitable for all surface treatments. The plastic products are especially suitable for 3C products with signal receiving and receiving, especially in areas near the antenna cover, such as Mobile-Phone, PDA, SmartPhone, GPS satellite navigation, Bluetooth headset, 3C products.
500万彩票The main characteristic of NCVM is that it combines the characteristics of traditional vacuum plating technology, adopts new plating technology and new materials, and makes different color metal appearance effect of ordinary vacuum plating, which plays a role in beautifying the surface of workpiece. The finished products manufactured by NCVM technology can be tested by tens of thousands of volts of high voltage meter without conduction or breakdown. It is precisely because of its non-conductivity that when the mobile phone or Bluetooth headset receives or transmits signals, the electromagnetic field generated is not deposited by the electric coating, thus not affecting the RF (radio frequency) performance and ESD (electrostatic discharge) performance of the mobile phone, that is to say, making the wireless products achieve better reception effect, no noise. It will not have any impact on the human body. From the point of view of electrical performance, it can pass conductivity test and electronic interference test. From the vacuum coating itself, it can guarantee normal physical and weatherproof testing, such as adhesion, wear resistance, alcohol resistance, artificial sweat resistance and high temperature and humidity storage. When NCVM process is adopted in the chassis of communication products, the antenna module of the product does not need to be re-designed to be grounded to the machine board, which can save the detection on the antenna module and the cost; at the same time, the appearance of the product has a strong metallic texture, thereby improving the technological content of the product and increasing the added value of the product.
