The factory’s sand management and processing conditions are considered to be better than the average plant, and the original is the uniform sand distribution. The core sand is grinded and mixed, and the sand is filled with sand and sand. The surface sand is uniform sand, and the sand for uniform grinding and mixing is about 14 tons per day. There are four sand-sanding machines in the sand-taking equipment and a sand-shaping laboratory in the workshop. There are seven people in the sand group and work in two shifts. The white shuttle door grinds sand, and the night shift removes a small part of wet sand.
