The most important part of equipment manufacturing industry is hydraulic system, which plays an important role in various engineering fields. The hydraulic pump in the hydraulic system is widely used, not only in agricultural related mechanical equipment, machine tool equipment, engineering mechanical equipment, automobile industry, petrochemical industry and other...
Molding manufacturing technology can be used not only in functional testing, but also in product conceptual design, and also in mold design and manufacturing. It is also widely used in the fields of medical treatment, household appliances, automobile and handicraft production. Rapid tooling manufacturing The solid model generated by...
Layered solid manufacturing The foil of hot melt adhesive is painted on one side, and the parts are heated. In this way, the foil and the surface of the part can be bonded together, and then the data information of CAD layered model can be obtained. Then, the gambling...
The pillar industry of China’s economic development is the modern machinery manufacturing industry. In order to promote the sound and rapid development of China’s economy, we must integrate with the international advanced manufacturing technology. In the 21st century, China’s network technology, computer technology, sensing and other high-tech rapid development,...
Gasified pattern casting is a new casting method in the late 1950s. Some aluminum castings for automobile lightweight, such as cylinder head and intake pipe, are made of sand core, but it is very troublesome to make and clean them in mass production. However, gasified die casting is used,...
Cosworth method is developed by Cosworth research and development company and GKN United Company in the mid-1970s. It is a sand mold low-pressure casting process, widely used in the automobile and aircraft industry. Its typical products are engine cylinder block, cylinder head, etc. The utilization rate of aluminum melt...
This kind of die-casting is a process between metal mold casting and die-casting. Under the action of pressure, the aluminum melt fills the cavity from one or two gates at the bottom along the riser, solidifies from the place far away from the gate, and gradually expands to the...
Pressure casting is called die casting for short. Under a certain pressure, the melt can fill the cavity. The structure of the casting is compact, the mechanical property is high, the dimension is precise, and the machining allowance is small. According to the pressure level, it can be roughly...
At present, the majority of machine tool castings are still gray cast iron. The practice at home and abroad has proved that high carbon equivalent and high strength are the development direction of gray cast iron. It is an important way for gray cast iron to obtain low casting...
For a long time, the material of machine tool casting in China is gray cast iron, and the standard of gray cast iron has been established. Why should the machine tool industry formulate the industry standard of the machine tool casting? This is because the machine tool as the...
