                How many factors are needed to prepare for plating?

                Usually, the factors considered include the following important aspects when preparing for electroplating. The electroplating plant uses the principle of electrolysis cell to deposit metal coating technology with good adhesion but different properties and matrix materials on mechanical products. The coating is even and generally thinner than the hot dip coating, ranging from several microns to dozens of microns. Through electroplating, the surface layer of decorative protection and various functions can be obtained on mechanical products, and the worn and machining errors can also be repaired. Electroplating process of plating on some metal surfaces with a thin layer of other metals or alloys by electrolysis is a process of attaching a layer of metal film to the surface of metal or other materials by electrolysis, thus preventing metal oxidation (such as corrosion), improving wear resistance, electrical conductivity, reflective property, corrosion resistance (copper sulfate, etc.) and improving aesthetics. Many coins are also plated on the outer layer.

                1. the essence of the material of the substrate

                As a variety of substrate, the structure, molding method, processing history, etc. are selected in close contact with plating solution and treatment scheme. Parts are made of different materials, cast, forged, hot or cold, whether by various molding methods such as heat treatment, and the treatment is different and different preparation. For key components, it is necessary to consider its experience and process scheduling scheme when dealing with environment or historical work.

                2. surface cleanliness

                On the surface of processed parts, we can all have a processing and various social materials, such as debris, oil dirt, oxide film or oxide material film, heat treated oil layer, adhesion of various social substances, and also different environmental pollution materials, including wax, thick oil seal oil layer, thin layer antirust oil film, corrosion inhibitor, etc., which need to be used with different ones Methods to analyze the processing. For example, thick grease and thin oil film, cleaning methods with different requirements must be developed.

                3. corrosion resistance, size, quantity and precision of parts and materials

                Some materials are susceptible to corrosion, such as aluminum, magnesium, zinc, etc.; some will be dissolved in anodizing treatment, such as chromium, tin, etc.; and the combination of porous, PM products and slit or strip is to be solved by different measures. Especially large, small, small and more complex shape or dimension precision parts are considered to be corresponding processing methods.

                4. structure and state of surface

                The surface structure of the coating material will directly affect the structure and characteristics of the coating, and the porosity of the rough surface is high, and the students will easily lead to underplating, and the rough inner hole is difficult to cover. In such cases, the enterprise should be taken into account when the work is arranged for construction. The same process research method can not fully adapt to a variety of surfaces, otherwise, the quality of products and services produced by the society will be different.
