Investment castings, also known as lost-wax castings, are precision components produced by pouring molten metal into ceramic molds formed around wax patterns. This process enables the creation of complex shapes with tight tolerances and smooth surface finishes, reducing the need for secondary machining. Investment casting is suitable for a wide range of metals, including stainless steel, carbon steel, aluminum, and superalloys. It is widely used in aerospace, automotive, medical, and industrial equipment industries. The process is ideal for producing intricate, high-precision parts in small to medium batches.
