The general term for precision casting is to pour the molten metal material metal-water concrete into the casting entity model that looks like the part, and after the casting is refrigerated, the casting product of ours is established. The casting methods include sand casting, special casting, precision casting, V method casting, and the precision casting in precision casting belongs to special casting. Aluminum dihydrogen phosphate precision casting The parts cast by this method do not require production and processing, or can be applied with a little production and processing.
Precision casting must give full play to its leading role and exemplary role, but the prerequisite for precision casting to give full play to these two functions is strength itself. Therefore, precision casting in my country should be given priority to develop and grow, and the development trend must be Clear goals and overall goals for progress.
The specification accuracy of precision castings is interfered by many factors such as casting structure, casting material, mold making, shell making, sintering, pouring, etc. The setting and unscientific operation at any stage will cause the casting to shrink. The rate causes a change, resulting in an error between the casting specification accuracy and the regulations. The accuracy of castings obtained by various casting methods is different, the initial project investment and production efficiency are inconsistent, and the economic benefits are also different. Therefore, in order to achieve more, faster, better, and more economical, it should be applied to all fields. Solve the casting method used to carry out a basic cost estimate to identify the casting method that is economical and can ensure the specified casting.
