The price competition of foundry products is becoming more and more fierce, which is bound to enhance the competitiveness of products from the production cost. Wuan scrap steel, scrap iron and other waste is rich, low price. If the direct sand casting smelting casting, accounting for more than 50% of the charge, the product cost can be greatly reduced. The question now is, how to use this waste for smelting? How to ensure material quality? Has formed 5-10 meters of super heavy duty and special needs CNC vertical turning and milling manufacturing capacity, is a collection of R&D, casting, processing, assembly as one of the high-tech enterprises. Need to solve the problems of the foundry company: at present, the company's technical strength has some difficulties in meeting the growing demand of production scale, which needs to be further improved. Mainly include: the introduction of advanced design, processing and assembly technology, the introduction of high-end machine tool industry talents. In order to meet the production needs, to ensure that the company developed into a "heavy, super heavy machine tools" one-stop development, production, sales of high-tech enterprises.
