Steel precision casting, also known as investment casting or lost-wax casting, is a manufacturing process that creates metal parts with high precision and intricate details. The process involves creating a wax pattern of the desired part, coating it with ceramic materials, and then melting the wax to leave a hollow ceramic shell. Molten steel is poured into the ceramic mold, creating the final metal part after cooling. This method allows for complex shapes, tight tolerances, and excellent surface finishes, making it suitable for aerospace, automotive, and medical industries.
