压射速度
[机] injection speed
- 然后，本文通过正交试验的方法研究了压射速度、浇注温度和模具预热温度对铸件缩松缩孔缺陷的影响。
By use of orthogonal test design, how the injection speed, pouring temperature and mold temperature effects the casting shrinkage porosity forming is studied. - 找准慢压射到快压射的切换点，选择好快压射的冲头速度，对保证压射速度的准确性作用明显。
It is effective to determine the switch point from slow injection to fast injection and to select punch velocity of fast injection for ensuring ejection speed. - 在优化压铸工艺参数的基础上，借鉴慢压射理论，进一步研究了慢压射速度对压铸过程卷气的影响。
On the basis of optimization of die cast parameters, the effect of slow shot velocity on air entrapment during die cast was studied further according to slow shot theory.
