permanent mould

基本解释

Through the adjustment of coating formula and thickness, the service life and the casting quality of permanent mould could be enhanced.
通过调整涂料的配方与厚度，提高金属型的使用寿命和铸件的品质。
Therefore, the ZL108 alloy modified with P is easier to appear porosity defects than with Na at the same permanent mould and process condition.
所以，同一铸型及工艺的条件下，磷变质ZL108合金比钠变质ZL108合金更容易出现缩松缺陷。
The results are as followings:(1) Compared with the permanent mould casting AZ91D alloy, the thixoformed AZ91D alloy has relatively higher SCC resistance.
与金属型铸造AZ91D镁合金相比，触变成形AZ91D镁合金都具有良好的抗应力腐蚀开裂的能力。
