                                            How to improve the surface quality of aluminum castings In general, an important way to improve the surface quality of aluminum castings is by electropolishing. Electropolishing means that the surface of the casting is changed by electrolysis so that a substance called an oxide film is formed on the surface of the aluminum casting. Overall: the use of electrolytically polished aluminum castings has considerable surface variations. For example, there are obvious enhancements in the color of the surface, the degree of corrosion resistance, the degree of wear, and the hardness; of course, the most important thing is the protection of the metal surface. It has also been said that anodizing will also achieve the effects we have mentioned above. Therefore, here is a point: since the raw material of the cast alumin...

                                     Ten things that must be paid attention to in precision casting! 1. Unblock all obstacles to the channel and site. 2. Check if the ladle is dry, whether the bottom of the bag, the ear, the bag and the end are safe and reliable, and whether the rotation is flexible. Do not use dry Iron ladle. 3, all tools in contact with molten iron, must be preheated to 500 degrees Celsius before use, otherwise it should not be used. 4, the ladle should not exceed 80% of the volume, the ladle should be smooth and slow, keep the steps to prevent the overflow of molten iron. Cast iron 5, before the crane crane should check the iron of the hook, the chain is reliable, the chain is not allowed to knot, there is a person responsible for tracking the iron in the water There must be no staff on the line. 6. Strictly implement the "six will not fall...
