What is Investment Casting?

Investment casting, also known as lost wax casting, is a manufacturing process in which metal parts are made by injecting molten metal into a ceramic mold formed around a wax pattern. This process produces highly detailed and complex metal parts with extreme dimensional accuracy.

Investment casting produces complex, high-precision parts and plays a vital role in manufacturing. The process is vital for industries that require parts with complex geometries and tight tolerances, such as aerospace, automotive, medical devices, and industrial machinery. It ensures that every part meets the highest standards of quality and performance, making it the preferred choice for high-precision applications.

Investment Casting Process

Yonglihao Machinery’s investment casting process ensures that every part we produce is of high precision and quality. The steps involved are:

Creation of the model: A wax model is first created to replicate the desired part. The wax model is made with a high degree of precision to ensure that the final metal part meets the exact specifications.

Mold Creation: The wax model is then coated with a ceramic material to form the mold. Several layers of ceramic are applied to create a strong and durable mold that can withstand the high temperatures of molten metal.

Dewaxing: Once the ceramic mold is complete, the wax inside is melted and removed, leaving a hollow ceramic mold.

Pouring Metal: The ceramic mold is preheated to the proper temperature and the molten metal is poured into it. This step ensures that the metal fills the mold completely and accurately, replicating the details of the original wax pattern.

Finishing: Once the metal has cooled and solidified, the ceramic mold is broken and the casting is removed. The final steps include polishing, machining, and surface preparation to achieve the desired finish and dimensions of the part.

Materials Used

Yonglihao Machinery uses a variety of high-quality materials in the investment casting process to meet the different needs of different industries.

Surface Finishing

Yonglihao Machinery offers a variety of surface finishes and treatments to enhance the performance, durability, and appearance of investment cast parts.

Anodizing: Improves the corrosion resistance of aluminum parts by forming a protective oxide layer. It also adds color to the metal, enhancing its aesthetics and durability.

Powder Coating: The surface of the metal is coated with a dry powder that is heat-cured. The result is a strong, durable finish that is resistant to corrosion, chipping, and fading.

Plating: A thin layer of metal, such as nickel or chromium, is deposited on the surface of the casting. It improves surface hardness and corrosion resistance and provides an attractive finish.

Passivation: This chemical treatment removes free iron from the surface of stainless steel and enhances its corrosion resistance.

Polishing: Polishing improves the surface finish of castings, making them smooth and shiny.

Heat Treatment: Heat treatment processes such as annealing, hardening, and tempering are used to modify the mechanical properties of castings. These treatments increase hardness, strength, and ductility. Thus, meeting the application requirements.
