After the plastic mold is used up, in order to prevent rust and corrosion, usually apply lubricant or grease on the mold working surface. If the rust on the surface of the mold is to be removed, small pits and corrosion marks are usually left on the surface of the mold. This type of defect is often fatal for plastic molds. By electrochemical plating, the surface of the mold can be plated before storage, and the thickness of the plating layer can reach 50 m. After plating, if necessary, you can apply a lubricant or grease. For corrosion protection, a plating thickness of 1 2 m is sufficient. When it is necessary to use the mold, the partition can be removed to bring the mold working surface to the initial molding state.

Applications 3 Conclusion <br> <br> electrochemical plating method in this field of aerospace and maritime plastic mold is only a few years ago, but by virtue of its simple, easy to use, cost savings and other advantages, this process The application of the method in the plastic mold industry is developing rapidly. Electrochemical plating will play an important role in the plastic mold industry due to its unique advantages, which are mainly reflected in:
Good social benefits Plastic molds have high manufacturing technology requirements, long production cycle, high processing costs, and large demand for mold materials. Many precision plastic molds need to be imported from abroad, and the cost and various expenses are high. If it is abandoned prematurely, it is not only economic waste, but also a waste of resources. The use of electrochemical plating for the repair of plastic molds or surface strengthening treatment can not only meet the needs of the industry, but also save money and at the same time play an environmentally friendly role. (2) There are important economic benefits. For example, a manufacturer of St. Louis produces a plastic cup with a logo for TwA, and the logo of the airline is printed on one side of the cup. When electrochemically electroplating copper and nickel at the inscribed mark and then plating a layer of nickel-tungsten alloy, the surface of the mold is repaired. It has now produced thousands of applications in unequal equipment for more than 20 years, and in marked plastic cups. This saves the company a lot of money by not having to spend a lot of money to open a plastic mold with an unmarked cup.
