In recent years, the domestic oil pump casting industry has grown at an average rate of more than 16%. Casting oil pump accounts for about 5% of the total output value of all kinds of oil pumps, with an annual growth rate of up to 25%, and the development is very active. With the development of vehicles, motors and other products to the direction of lightweight, the number of die casting die, life and complexity level will put forward higher and higher requirements.
According to the statistics of "Basic Situation of Professional Oil Pump Factories in China" compiled by the Operation and Management Committee of China Oil Pump Industry Association, in recent years, China's oil pump casting industry has grown at an average rate of more than 16%, which is more than twice the average value-added of China's GDP. Using this die casting technology can reduce development time by 50-80% and manufacturing costs by 30-50%. Therefore, the newly developed digital die less casting precision forming technology and equipment, directly from the sand processing. At present, there are more than 30,000 foundry enterprises in China, and the annual production of die castings in China exceeded 40 million tons in 2011, consuming a large amount of wood and metal. The proportion of die casting in oil pump industry will continue to improve. The parts formed by oil pump show high precision, high complexity, high consistency, high yield and low consumption, which can not be compared with other processing and manufacturing methods. The technical personnel only need to use the computer to make the 3D CAD model of THE KCB gear pump of the die-casting parts required, and then input the automatic planning path to the precision molding machine without mold casting, and the other work can be completed by the machine. The use of raw materials, backward technology and inadequate supporting system of die casting oil pump industry, these are the bottlenecks facing the development of China's die casting oil pump industry, only through these bottlenecks, China's casting oil pump industry is likely to achieve development. In casting production, sand casting is the most widely used, about 80% of the world's die castings are made of wood mold metal mold sand casting. Therefore, digital die - less casting precision forming technology has been called the revolution of die - casting technology.
