Spiral blade is the core component of spiral conveying equipment, but due to the reasons of space surface, its manufacturing technology is relatively backward, especially the manufacturing technology of large thickness diameter spiral blade is relatively backward, far meeting the needs of construction. Machinery, mining machinery other large machinery field. In order to meet the market demand, our company has successfully developed a new technology special equipment for manufacturing large spiral blades. After the products are put on the market, the demand is very strong. Our factory is a manufacturer of thick blades (such as spiral blades dies) machining. In recent years, spiral blade has been widely used in many fields, such as agricultural machinery, electric power, light industry, food, chemical industry, pharmacy, construction, mining, cement, metallurgy so on. The spiral blade produced by continuous cold rolling method overcomes the shortcomings of traditional spiral blade production process, such as poor precision, difficult forming, high material consumption low production efficiency. After forming, the blade has smooth surface, high dimensional accuracy surface hardness, can also provide continuous integral blade according to the screw length required by customers. It has good rigidity is easy to weld assemble in use. Our factory pursues the tenet of "relying on scientific management, manufacturing products, meeting customer needs", has won the recognition praise of customers.
