| Objective To solve the problems found in the casting process of small-sized aluminium alloy squeeze casting parts such as big error in casting weight, poor consistency in the structure, shrinkage in the hot spot region, and meanwhile to increase the material utilization rate. Methods The quantitative precision molding technique was introduced into the practical production. Conclusion The application of quantitative precision molding technique could effectively solve the problem of large error in casting weight during the casting of small-sized aluminium alloy squeeze casting parts, and the error of weight could be controlled within ±0. 02 kg, which thus solved the problem of big error in wall thickness caused by the large weight error. It also solved the problems of poor consistency of the cast structure and the shrinkage in the hot spot region, and improved the utilization rate of the material. |
