The quality of materials is the key factor affecting the precision of castings copper. First of all, the main material is metal, but we should pay attention to which bulk materials are not pressed into cylindrical shape, and different materials will be easy to mix. That is to say, the metal materials used in precision casting should be pressed as cylindrical as possible. In order to ensure the performance of the product, the surface of the casting will be coated. Therefore, the surface coating as an important raw material is also very important. The surface coating is usually zircon powder. The molding of castings has a great relationship with the mold, and the quality and performance of the mold material are also very critical. We must choose products made by legitimate manufacturers.
As an additive used in the casting process of castings copper, various physical and chemical parameters of silica sol should also be guaranteed. Castings copper are usually formed by applying a certain amount of pressure to the material and extrusion, so it is necessary to store them in a ventilated and dry environment as much as possible. In the case of unqualified temperature or humidity, it will also have a certain impact on the use of castings copper.
Contact with other chemicals must also be avoided. Once chemical reactions occur, serious consequences are bound to result. The main raw material of castings copper is copper. As an active element, it is easily affected by the surrounding environment.
In addition to the above situations, if the workpiece is exposed to the sun for a long time, it is also unfavorable, so we need to avoid oxidation reaction. In addition to chemicals, castings copper cannot be in direct contact with water, which can also cause undesirable phenomena in the castings.
