How to Control Quality in the Electroplating Industry?
We all know that many metal materials are not only scarce in resources and expensive, but also directly exposed to oxygen and water, which will greatly reduce their useful life. So insiders will always plate a protective coating on the surface. The protective performance of this protective layer is inseparable from the coating thickness. In many electroplating processing industries, people use coating thickness gauges to grasp the coating thickness to ensure that the thickness of the coating is within the standard range and can exert the maximum protection effectiveness.
1. The plating layer is too thick
Generally speaking, the thickness of the electroplated coating is better if it is within the allowable range. However, after the coating thickness exceeds the normal range, the most obvious problem is the waste of the coating material, which raises the cost invisibly. In addition, it will greatly affect the conductive properties of the material. Thicker coatings often lead to larger cover surfaces and larger overall volumes. Therefore, the thickness of the electroplated coating can be measured at any time by using the coating thickness gauge.
2. The plating is too thin
The most fundamental problem caused by too thin plating is that the metal substrate cannot be completely covered. The external oxygen, water, acid, alkali and other components penetrate into it, so that the plating coating cannot achieve the purpose of protecting the substrate. It is very unqualified. Therefore, most manufacturers will use coating thickness gauges to avoid coatings that do not meet standards and reduce the occurrence of bare metal substrates.
3.Uneven thickness of electroplated coating
The uneven thickness of the plating layer is also a problem that should be avoided in the plating industry. The uneven thickness of the plating layer is likely to affect the anti-corrosion performance. The excessively thick place is too rough and uneven. The excessively thin place is very poor in gloss. It looks dark and moldy and has poor protective performance. Therefore, no matter from the aspects of corrosion resistance, appearance, machining performance, etc., The factory and the purchaser hope to greatly improve the uniformity of the coating thickness. Correct and effective use of the coating thickness gauge can better achieve this purpose.
The above three points are the common quality control problems in the electroplating industry. The only and most effective solution is to use a coating thickness gauge for testing. Many people may not know much about coating thickness gauges. In fact, Linshang coating thickness gaugeLS223 is very effective. Because there are many different metal substrates in the electroplating industry and the required coating materials are not the same, this requires that the coating thickness gauge can have a large measurement range. This LS220H coating thickness gauge can be used for testing different types of electroplating materials and nondestructive testing can be done in a short time.
