What do you need to pay attention to when electroplating mold?
Author:
Mold plating is an electrolytic process that provides the effect of plating metal on sheet metal such as anodes. The electrolyte is generally the ion solution of metal plating, and the effect of gold plating is negative. After the voltage is input between the anode and the cathode, the metal ions in the electrolyte are attracted to swim to the negative electrode and are inlaid after repair. At the same time, the anode metal is remelted to provide better metal ions for the electrolyte. Under some conditions, the application of insoluble anodes, it is necessary to add new electrolyte to supplement the plating metal ions.
When the mold is plated, the plated metal or other insoluble material is the anode, the workpiece to be plated is the negative electrode, and the positive ions of the metal to be plated are restored on the surface of the workpiece to be plated to produce the coating. In order to eliminate the influence of its positive ions and make the coating uniform. Firmly, it is necessary to use a solution containing metal cations as a plating solution to maintain the concentration of metal cations in the coating. The purpose of electroplating is to apply a metal coating on a substrate to change the surface characteristics or specifications of the substrate. Electroplating can enhance the corrosion resistance of metals (most coating metals should be corrosion-resistant metals). Increase hardness. Avoid wear and tear. Improve conductivity, smoothness, heat resistance and beautiful surface.
Features:
1. Improve the corrosion resistance of metal manufacturing or parts. For example, the surface of steel products or parts is galvanized.
2. Improve the protective decoration performance of metal manufacturing. For example, the surface of steel products is plated with copper. Nickel plating, chrome plating, etc.
3. Repair the size of metal parts. For example, the shaft. Gears and other key mechanical parts damaged after use, can take iron plating. Chrome plating and other misfortune its specifications.
4. Plating can also give some products or parts some special effects. For example, hard chrome plating can improve its wear resistance.
Note:
Because of the development of new technologies and aluminum templates, especially plastic mold design, aluminum molds are becoming more and more commonly used for blow molding. R.I.M. Rubber mold. Construction of foaming molds and R.T.M. molds and other industries. Although it may not be suitable for all application industries, its application has actually become more widespread. Everyone hopes to increase the production and service life of the mold, such as the traditional tool steel mold, hard chromium or nickel metal plating or more professional engineering coatings, to avoid its surface damage or corrosion, to promote its better out of the mold. Since then, in order to find the same goal, we widely used aluminum mold, and found a specific solution.
