一：investment-casting是什么意思（中英文）解释的意思：

investment-casting是一种金属铸造技术，也被称为“失蜡铸造”或“熔模铸造”。它是一种制造精密零件的方法，通过将熔化的金属注入到具有精确形状的模具中，然后冷却固化，最终得到所需的零件。这种方法可以生产出复杂形状、高精度和光滑表面的金属零件。

Investment-casting is a metal casting process, also known as "lost-wax casting" or "precision casting". It is a method of manufacturing precision parts by injecting molten metal into a precise mold and then cooling and solidifying it to obtain the desired part. This method can produce complex shapes, high precision, and smooth surface metal parts.
