在熔模精密铸造 (失蜡) 的过程，模具由 repeatedlydipping sprued 模式在建立周围到底壳的陶瓷浆料变硬。模具是随后蒸压 (蒸) 和/或加热孤岛模式。最后，熔化的金属倒入腔在哪里 itsolidifies。一旦冷却对象强制转换，外壳是破碎和被撤下部分。这一过程的关键优势是其将 producecomplex 金属零件能力迅速和廉价地无硬工具。

Inthe Investment Casting (lost wax) process a mold is created by repeatedlydipping a sprued pattern in ceramic slurry, which builds up a shell around itthat hardens. The mold is subsequently autoclaved (steamed) and/ or heated toeliminate the pattern. Finally, molten metal is poured into the cavity where itsolidifies. Once the cast object has cooled, the shell is broken and removedfrom the part. The key advantage of this process is its ability to producecomplex metal parts quickly and inexpensively without hard tooling.
