Hand painting not only pollutes the environment, but also causes great waste in the process of painting. If a set of coating can be attached to the surface of the workpiece, it can be dried quickly, without coating, effective, smooth surface, no beating. This device not only saves coating, but also gives the product a better appearance quality. This technical problem must now be solved for foundry castings. In view of the growing market demand at home and abroad, the demand for product quality is getting higher and higher. On the basis of full market research, combined with the current market conditions and energy saving planning, our company decided to combine its own advantages in technology, capital and sales channels, to upgrade the original production process, energy-saving transformation of casting rigging. But according to the production of casting materials, varieties and batches, how to reasonably choose clay wet sand, resin self-hardening sand, sodium silicate self-hardening sand, investment casting, lost casting, long mold casting (gravity, centrifugal, high pressure, low pressure, etc.) and other advanced modeling process. , as well as cold core box, coated sand shell core, hot core box and other core manufacturing process, research and development of automatic molding production line development of short process casting has become a new technology, the annual output of high-strength steel of 15,000 tons, annual output value of 500 million yuan, annual profit of 40 million yuan, accounting for more than 50% of the domestic large-scale transmission line market. Exports to Australia, India and other regions, is the power sector production of castings designated key production enterprises.
