Advantages of mini resin sand molding line:
1. Small investment and quick effect.
2Easy to transport, a standard 40-foot container can be loaded.
3. No debugging, can be used directly after power on, the supplier does not need to go to the site for debugging
4. The production efficiency of 3 tons of sand per hour can be mixed.
5. Low energy consumption.
6. The numerical addition amount is low, and the mixing is uniform.
7. PLC remote control, easy to use and maintain.
The resin sand molding process is more and more accepted and applied by foundry enterprises because of its clear and smooth surface contour, high geometrical accuracy and high dimensional accuracy; the production process is simple and easy to control. In recent years, with the continuous improvement of the quality requirements of mechanical products, including material, dimensional accuracy, and especially the improvement of surface quality requirements, the more advanced technology of resin sand has been vigorously promoted. In addition, with the treatment of raw sand and the improvement of resin, catalyst, sand mixing equipment and technology, the cost of resin sand has been reduced, and the promotion of resin sand technology has also been greatly promoted.
Features of resin sand molding:
1. High yield
The yield of iron castings is generally ≥92%, and can reach 96 to 98% in higher cases.
2. Smooth surface
It is 2 to 3 grades higher than ordinary wet clay sand modeling, and the surface roughness can reach Ra12.5.
3. High dimensional accuracy
Due to the high strength of the molding sand, the dimensional accuracy of the castings is 2 levels higher than that of the general wet molding sand and water glass sand, which can reach IT8 to 10 levels. The subsequent machining allowance can be reduced, and the tool wear is small.
4. The process is simple and easy to control
The resin sand molding process is a self-hardening type, and the main points of the process are guaranteed by the equipment. As long as the process parameters are mastered, the quality of the castings can be completely guaranteed. Therefore, the technical quality of the operators is low, and labor is saved and labor intensity is reduced. The unit area of the workshop Compared with the clay sand drying process, the casting output is doubled, and the sand cleaning efficiency is also greatly improved. At the same time, there are less dust spots and scattered sand, so the working environment is more tidy.
5. High work efficiency
The use of resin sand molding improves the work efficiency, increases the workload per unit area, and saves the workshop area.
6. Reduce labor intensity
Resin sand greatly reduces the labor intensity of core making, molding, sand falling and cleaning workers.
