In industrial usage, electroplated coatings are used for corrosion prevention, hardness to prevent scratches on a surface, creating lubricity or a low friction surface, to create a consistent, high-quality surface which will hold subsequent painting, or to create a conductive surface.
An electroplating line is an automated manufacturing system which covers machine parts with a coat of metal. It consists of a set of tanks that chemically process the items and hoists that transport the items between workstations. Scheduling the movements of these hoists is commonly called a hoist scheduling problem. The most common approaches to the problem are cyclic hoist scheduling problem and dynamic hoist scheduling problem.Shenzhen Keyou PCB Co.,Ltd is a professional high-tech pcb manufacturer that is engaged in PCB manufacturing including industry control PCB,medical equipment PCB,power supply PCB,amplifier PCB,automotive PCB,security surveillance.
Electroplating is a process for coating a metal part (usually) with a thin layer of another metal, forming an alloy with the part’s surface to bond the coating in place. The process involves the use of an electric current flowing through a circuit consisting of a cathode, an anode and a liquid solution. The part itself is connected to the electricity source, and thus becomes the cathode. The electricity source provides electrons to the part, creating a charge on its surface.
There is a practical limit to the coating thickness, and in general, it ranges from a very thin coating of less than 0.1 micrometer thick (.00004 in.) for quick "flash" coatings to about .060" as a maximum for chrome plating and up to .100" for nickel plating. The use of electroplating for decorative purposes only uses quite thin coatings, but we will be addressing those coatings of more use for industrial purposes.The solution and the process take place in a tank, which is called the bath. The electrical current and the amount of time during which the part is in the bath undergoing the plating process will determine the coating thickness.
