不銹鋼精密鑄造鎂合金的工藝要點如下,
The key points of magnesium alloy precision casting process for stainless steel are as follows:,
1.充分預熱壓鑄模和壓室到200~300℃之間以減緩鎂合金的凝固速度。
Fully preheat the die casting mold and pressure chamber to 200~300 ℃ to slow down the solidification rate of magnesium alloy.
2.從我們試驗的結果來看,3~4mm壁厚的精密鑄件對射速無明顯要求,鎂合金的填充時間為鋁合金的70%。
According to our test results, precision castings with a wall thickness of 3-4 mm have no obvious requirements for the injection rate, and the filling time of magnesium alloy is 70% of that of aluminum alloy.
3.壓鑄薄壁件需要高的射速以獲得高的充填速度。
3. Die casting thin-walled parts require high injection rates to achieve high filling speeds.
4.澆注溫度我們控制在705~715℃之間。
4. We control the pouring temperature between 705 and 715 ℃.
5.鎂合金精密鑄件的尺寸與鋁合金精密鑄件相比,經測量無明顯變化。
5. Compared to aluminum alloy precision castings, the dimensions of magnesium alloy precision castings have no significant changes after measurement.
