Low pressure casting method of history 　　The prototype of the low-pressure casting method can be traced back to the beginning of this Suitable for the aluminium alloy is 1917 in France, Germany, in 1924 application, but did not form large-scale industrial For commercial purposes is after world war ii began to produce the in 1945, M Lewis by Britain created o lu massey library company, start production storm-water pipeline, beer vessel After that the fifties, Austria and Germany began to produce cylinder 　　In 1958, American ze lots pull road, in small implied it car engine parts (cylinder head, body, gear box) was the widespread use al-alloy castings, and used the low pressure casting This is still widespread adoption of low pressure casting method is indispensable to promote, especially in the world of the car industry caused a tremendous Low pressure casting method was introduced into our country is in 1957 around, but the real cause the attention of industry, begin to have various research, bring equipment from about 1960 But this broken before the common sense the epoch-making technique, almost no riser, and has, as a kind of "technology" established gravity gold casting technology compared with completely different difficulty, so the industry's reaction compare 　　Under such circumstances, 1961 light car with air-cooling cylinder head production become low pressure casting method in our country in the meanwhile, the After developing very fast, in overcoming the multiple technical problems later, using low pressure casting method has the material utilization high and easy to implement note soup with advantages, automation car parts as the center, progressively establish light alloy castings main casting method is firm Currently in al-alloy castings production, low pressure casting supplies have accounted for about 50 percent, and with its huge production and excellent quality is famous in the Products branch out into car related components, such as the cylinder head, gas cylinder, brake drum, clutch cover, the wheel hub, inlet guhya pipe, Especially since 1970, widely used in the wheel hub, and along with the recent car lightweight and improve performance requirements, such as in past never had the complex internal quality and mechanical properties of the strict request, cylinder head, gas on cylinder body use will increase
