我厂某些压铸件气密性要求较高,因内部气孔报废相当多。为了解决这一问题,在上级领导的关怀下,在厂党委的领导下,我所与车间工人密切配合,学习兄弟单位的先进经验,开始了充氧压铸的试验研究工作。经过半年的试验,取得了初步成果,已于一九七三年投入生产。 Some of our factory die-casting requirements of airtight higher, due to internal stomatal collapse quite a lot. In order to solve this problem, under the leadership of superiors, under the leadership of the factory party committee, we worked closely with the shop floor workers to learn the advanced experience of our brother units and started the experimental research on oxygenation and die casting. After six months of trial, preliminary results have been achieved and production started in 1973.
