Abstract：
Aiming at the defect problems of porosity, sintering and sand hole in the production of 4D cylinder block, a number of technological measures, such as process correction, selection of special coated sand and coating, were adopted to effectively control the quality problems. It also summarizes the process of solving quality problems and further improves the analysis ability and control countermeasures of the defects of the dry cylinder block.
