ＮＣＶＭ是采用镀出金属及缘化合物等薄膜，利用相互不连续之特性，得到最终外观有金属质感且不影响到无线通讯传输之效果。要实现不导电，满足无线通讯产品的正常使用；其次要保证“金属质感”这一重要的外观要求；比较后通过ＵＶ涂料与镀膜层结合，比较终保证产品的物性和耐候性，满足客户需求。ＮＣＶＭ可应用于各种塑料材料，如ＰＣ、ＰＣ＋ＡＢＳ、ＡＢＳ、ＰＭＭＡ、ＮＹＬＯＮ、工程塑料等，它更符合制作工艺的要求，是无铬（Ｎｏｎ－Ｃｈｒｏｍｅ）电镀制品的替代技术，适用于所有需要表面处理的塑料类产品，特别适用于有讯号收发的３Ｃ产品，尤其是在天线盖附近区域，如Ｍｏｂｉｌｅ－Ｐｈｏｎｅ、ＰＤＡ、ＳｍａｒｔＰｈｏｎｅ、ＧＰＳ卫星导航、蓝牙耳机、3C产品。

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.

ＮＣＶＭ的主要特征是结合了传统真空镀膜技术的特性，采用新的镀膜技术、新的材料，做出普通真空电镀的不同颜色的金属外观效果，起到美化工件表面之功用。采用ＮＣＶＭ技术制出的成品可以通过高压电表几万伏特的高压测试，不导通或不被击穿。正是因为它的不导电性，当手机或蓝牙耳机收讯或是发射讯号时，产生的电磁场不被导电的镀层所屯积，从而不影响手机的ＲＦ（射频）性能以及ＥＳＤ（静电放电）性能，也就是说使得无线产品达到更好的收讯效果，无杂音，更不会对人体产生任何影响。从电性能角度出发，它能够通过导电测试和电子干扰测试。从真空镀膜本身，它能同时保证正常的物理和耐候测试，如附着力、耐磨耗、耐醇、耐人工汗液和高温高湿储存等。当通讯产品的机壳采用ＮＣＶＭ制程时，产品的天线模块不需再设计回路接地至机板上，由此可节省在天线模块上的检测，并节省成本；同时产品的外观金属质感较强烈，进而提高产品的科技含量，增加产品的附加价值。

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.
