Factors and control affecting the size of vermicular graphite cast iron engine castings
Combined with the characteristics of our company's peristaltic cast iron parts of high-volume assembly line production process,from the casting shrinkage design,core size control,core box mold maintenance,maintenance,melting process design and other aspects of the process to improve the di-mensional accuracy of the peristaltic cast iron engine castings are introduced,through a series of mea-sures to implement and validate the dimensional accuracy of the engine castings to achieve a stable DIN 1686 GTB15 tolerance requirements.
