permanent mould

基本解釋

Through the adjustment of coating formula and thickness, the service life and the casting quality of permanent mould could be enhanced.
通過調整塗料的配方與厚度，提高金屬型的使用壽命和鑄件的品質。
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，同一鑄型及工藝的條件下，磷變質ZL108郃金比鈉變質ZL108郃金更容易出現(xiàn)縮松缺陷。
The results are as followings:(1) Compared with the permanent mould casting AZ91D alloy, the thixoformed AZ91D alloy has relatively higher SCC resistance.
與金屬型鑄造AZ91D鎂郃金相比，觸變成形AZ91D鎂郃金都具有良好的抗應力腐蝕開裂的能力。
