web pvd coating machine is generally divided into two kinds of performance, one is functional and the other is decorative. Many customers do not know the difference between these two functions, and they do not know the specific difference. Technical equipment for the continuous coating of films on flexible substrates by vapor deposition. According to the working principle, the common vacuum winding coating equipment are: magnetron sputtering winding coating, evaporation winding coating and combined winding coating. According to its use, it can be divided into: decorative film winding equipment, packaging film winding equipment and functional film winding equipment on the flexible substrate. So what is the functionality and decoration of the winding pvd coating machine? The following is a compilation of small series and a detailed introduction to everyone.

The function is to use different coating methods to coat semiconductor films, metal films, insulating films, optical multilayer films and other films on flexible substrates such as plastic films, paper, metal tapes, and cloths, which can not only improve its surface hardness, mechanical strength and Water resistance can also increase oil resistance and solvent resistance, improve aging resistance, and make it conductive, absorbent, reflective, insulating, barrier, and prevent static electricity, etc., so that these flexible materials have some special functions. Or due to the formation of a metal or ceramic film, the intrusion of water and solvents is prevented, and it is not corroded by chemicals, which is convenient for welding.
 Decorative is to use the luster and color of various metal and optical films to make them more beautiful, durable, and expand their scope of use. For example, metallization and dielectric film on the plastic surface can make the plastic have a strong metal or dielectric light layer to make a reflector and a radiation radiator; it can also make the plastic look like a metal product for decoration.
 The above two performances of the web pvd coating machine have different advantages and uses, and the effects and application fields are also different, and each has its own advantages. To choose a pvd coating machine with performance, it is still necessary to first see what products the customer is coating and what are the requirements, and then determine which type of wed pvd coating machine to purchase.
