Low-pressure casting technology in the 21st century vision
High-3m, 6mm wall thickness of the pressure casting. (2) The number of aluminum automotive engine parts such as exhaust pipes, motorcycle engine cylinder head and cylinder head, cylinder head and the wheel is still now a large number of metal gravity die casting. In particular, aluminum alloy wheels, most of the start of low-pressure casting, low pressure die casting equipment now because can not meet the technical requirements, low productivity,[link widoczny dla zalogowanych], many of the original manufacturers to turn the clock back by low pressure casting and gravity die casting method with metal production. However, with advances in technology, including cars, motorcycles cylinder head, cylinder head, exhaust manifold and the hub will produce a large number of low-pressure casting method, so casting to improve the quality a notch. (3) quality than 10O0kg more large centrifugal pump stainless steel impeller (cF ~ 3M,[link widoczny dla zalogowanych], CD a 4MCu), leaf thickness and area, and the journal section of large size, casting uneven thickness, and the work environment under stress corrosion . When conventional gravity casting sand casting shrinkage is more serious. Life in corrosive environments shorten. In the low-pressure casting equipment such parts under the premise of a complete, resin sand casting or low pressure graphite cast into a compact structure is expected, the size of high quality precision castings. Such casting equipment in nuclear power has an important position. References 1 Luo G students, Zhang Zhizhong, Lvyou Gang and so on. Low pressure casting.
