Investment casting refers to a method of manufacturing casts by producing molds using finely crushed fire-resistant materials, and pouring in melted metals with the moisture of molds and organic matter removed by means of firing.

In ancient times, this method was also adopted in Egyptian culture and ancient Chinese casting technologies. Today there is a huge range of industrial goods manufactured using this method, covering various fields from relatively large items such as aircraft parts through to small items such as golf club heads, valves, automobile parts, communications device parts, and materials for dental treatments, etc.
