PVD coating can provide products with color, making the appearance of the workpiece more attractive , while adding durability, wear resistance, and corrosion resistance to extend its service life; used in various fields of the hardware industry, such as doorknobs, tableware , Bicycle forks, bathroom hardware, electronic products (mobile phones, cameras, computers), ceramic art, golf heads, etc.
The application of PVD technology to watches has gradually become a trend. Watchbands and cases can improve hardness, wear resistance, and corrosion resistance while also reflecting personal characteristics and favorite colors.
Many watch cases are presented in gold, silver, bronze, rose gold, and black through the PVD process. DLC coating are also used to provide ultra-high hardness, excellent corrosion resistance and anti-wear performance while maintaining the desired attractiveness.
Diamond diaphragmThe sound heard from speakers and headphones comes from the movement of the diaphragm, and the material of the diaphragm determines the presentation of the tone and sound quality; it needs the characteristics of rigidity in the center to withstand severe vibration without failing. The DLC coating has a wider sound range, and excellent front and rear extensibility of the audio, with a clear hierarchy in the high frequency part level based on the Young modulus coefficient expansion measurement. Therefore, the diamond coated diaphragm has become a way of expression in the audio and headphone industry.
