Resin bonded sand equipment comes with the development of coated sand technology. At present, the domestic resin bonded sand equipment mainly includes full-automatic and semi-automatic. With the development of casting technology in China, resin bonded sand equipment is more and more widely used, and the technology of resin bonded sand equipment has also been greatly improved. The amount of resin added is also getting lower and lower at the end of the month. The gas output of resin sand equipment is small, which also greatly reduces the production cost.
At present, the production technology of domestic resin sand equipment has generally tended to be improved, but there are still some deficiencies in some aspects. The improvement technology of resin sand equipment should continue to move forward, which is conducive to the long-term development in the future. With the development of new casting technology, resin sand equipment has been widely used. The production technology of resin sand equipment has also been greatly improved. The resin addition of resin sand equipment has been reduced from 2-3% to 1.5-1.7%. Due to the low amount of resin added, the gas output of resin sand equipment is small, and the production cost is greatly reduced.
