Under normal circumstances, the surface of high-precision copper castings is basically relatively rough, with many holes, and the surface of the metal sheet is not clean, covering sand, white wax and other chemicals. If it is not washed as soon as possible, it will be difficult to remove it. Therefore, after cleaning the surface of the cast copper parts, a layer of silver is coated on the surface of the high-precision cast copper, which is more up to standard. becauseDongguan Precision CastingofThe characteristics of high-precision copper castings, and its electroplating regulations are very strict, and then satisfactory products can be cast. However, the key is to pay attention to the fact that in order to better prevent the interference of the casting process, the copper must be cleaned in the voids between the residual aqueous solutions. If there are residual chemicals inside, it will interfere with the next step of casting. The copper casting time will be longer than everyone thinks, so everyone must be patient. Long-term maintenance of the color balance of the coating, sometimes casting too fast is not a good thing, so it is often impossible to maintain quality and quantity.

Advantages of copper casting

(1)Dongguan Precision CastingofCopper castings can be made from inner cavities, and the shape is complicated. Such as various shells, CNC lathes, cylinder blocks, cylinder heads, etc.

(2) Flexible processing technology and wide adaptability. The specifications of liquid molding are basically endless. Its net weight can range from multiple to hundreds of tons, and the wall thickness can vary from0.5Mm to1M up and down. Industrial production can be dissolved into liquid metal raw materials, which can be used for liquid molding. For pig iron that is not easy to cast, liquid forming is the only way to produce billets or parts.

(3) Low cost of liquid molding. Liquid molding can be directly applied to waste and cutting, and the input cost of machinery and equipment is low. In addition, the remaining amount of liquid molded parts processed is small, saving metal materials.

Everyone uses door handles, anti-theft lock cores, heat pipe radiators, water pipes, electric water heaters, iron, etc. These are basically high-precision copper castings. In fact, the use of high-precision copper castings in my country can be said to have been used for thousands of years. There were copper castings for thousands of years. Contemporary sand mold casting is more widely used, accounting for the total output value of castings.80%up and down. Rare metal castings such as aluminum, magnesium, and zinc are mostly castings. In the machinery and equipment industry, some precision machining can also be directly used as part of the equipment.
