OEM custom electric gold plating chrome parts Service
Short Description
Is using the principle of electrolytic plating on some metal surface on a thin layer of other metal or alloy plating process, is the use of electrolytic action made of metal or other materials adhered on the surface of the parts of a layer of metal film technique to prevent metal oxidation (rust), improve the wear resistance and electric conductivity, reflective, corrosion resistance and improve aesthetics, and so on.
Product Description
Coating is mostly a single metal or alloy, such as titanium palladium, zinc, cadmium, gold or brass, bronze, etc. There are also dispersion layer, such as nickel - silicon carbide, nickel - fluoride fossil ink; There are cladding layers, such as copper - nickel - chromium layer on steel, silver - indium layer on steel and so on. In addition to iron based cast iron, steel and stainless steel, there are also non-iron metals, or ABS plastics, polypropylene, polysulfone and phenolic plastics, but the plastics must undergo special activation and sensitization treatment before electroplating.
The electroplating process is basically as follows:
Plated metal at anode
The material to be plated is at the cathode
The anode and cathode are connected by an electrolyte solution of positive ions of the plated metal
When a direct current is applied, the metal at the anode oxidizes (loses electrons) and the positive ions in the solution are reduced (gains electrons) at the cathode to form atoms and accumulate on the cathode surface.
The beauty of electroplated objects after electroplating is related to the size of the current, the smaller the current, the more beautiful the electroplated objects will be; Otherwise, there will be some uneven shapes.
The main uses of electroplating include protection against metal oxidation (e.g. corrosion) and decoration. Many coins are also electroplated.
Effluent from electroplating, such as defunct electrolytes, is a significant source of water pollution. Electroplating process has been widely used in semiconductor and microelectronics components lead frame process.
VCP: vertical continuous electroplating, new machine for PCB, better quality than traditional suspension electroplating
Aluminum plating solution formula process flow:
High temperature weak alkali etching → cleaning → pickling → cleaning → zinc immersion → cleaning → secondary zinc immersion → cleaning → pre-copper plating → cleaning → pre-silver plating → cyanide bright silver plating → recovery washing → cleaning → silver protection → cleaning → drying.
From the process, the selected protective material must be resistant to high temperature (about 80℃), alkali resistance, acid resistance, secondly, the protective material can be easy to peel off after silver plating.
