求翻译：在选取氧化工艺之前，应对铝或铝合金材质情况有所了解，因为，材料质量的优劣、所含成份的不同，是会直接影响到铝制品阳极氧化后的质量的。关于这一点，我们工程师有专门研究。考虑到你要的产品尺寸比较小，我们工程师建议使用美国牌号为A380（德国牌号为AlSi8Cu3)的铝合金进行高压铸造。是什么意思？

Before the oxidation process in the selection, aluminum or aluminum alloy should understand the situation, because the merits of quality of materials, which contain different ingredients, it will directly affect the oxidation of the aluminum anode quality. On this point, we have specialized engineer

Sulfur dioxide, and should be selected before the craft aluminum or aluminum alloy material circumstances, because you have to understand the pros and cons, and quality of the materials containing ingredients, the difference is that can have a direct impact on the quality of post-anodized aluminum p

In front of selection oxidation craft, should has the understanding to the aluminum or the aluminum alloy material quality situation, because, the material quality fit and unfit quality, contain the ingredient difference, is can affect directly after the aluminum product anodic oxidation the quality

Before choosing oxidation process, aluminum or aluminum alloy material sense, as, quality of materials, contain elements of different, will directly affect the quality of Anodic oxidation of aluminum products. This connection we engineer who specializes. Consider your product is relatively small, we

In front of selection oxidation craft, should has the understanding to the aluminum or the aluminum alloy material quality situation, because, the material quality fit and unfit quality, contain the ingredient difference, is can affect directly after the aluminum product anodic oxidation the quality
