Investment casting achieves a fine surface finish and high dimensional accuracy. Question 33 options: True False

Answer

The statement "Investment casting achieves a fine surface finish and high dimensional accuracy" is True.

Investment casting, also known as lost-wax casting, is a manufacturing process that involves creating a wax pattern of the desired part, which is then coated with a refractory material to create a mold. Once the mold is formed, the wax is melted away, leaving behind a cavity in the shape of the part.

This process is capable of producing complex geometries with high precision and fine surface finishes, making it suitable for various applications, including aerospace, medical devices, and intricate components. Therefore, the correct answer is True.
