Lost foam casting affects the accuracy factor

In lost foam casting, in general, the factors affecting the dimensional accuracy of castings are many, such as the structure, shape, size of the lost foam casting itself, the influence of foam quality, the influence of paint coating, the influence of modeling and pouring links in the casting process, etc.
In the whole lost foam casting process, the pouring process is one of the most important links, the pouring system, pouring speed, pouring temperature, pouring process four factors are the key processes to improve the quality of castings, only continuous improvement, continuous improvement, in order to cast high-quality castings.
Coating coating also has a great impact on the accuracy of lost foam castings, coating performance, coating thickness can affect the size of the mold, thereby affecting the dimensional accuracy of castings, so lost foam casting, the coating should have good performance, sufficient strength, and the coating operation process should be reasonable.
