3. Ceramic Shell Casting Similar to investment casting, ceramic shell casting utilizes a ceramic shell mold. However, it often involves multiple layers of the ceramic coating to enhance the strength and durability of the mold, allowing for high precision and surface quality.

Mold coatings are applied to the interior surfaces of the sand molds to improve release properties and minimize defects in the final casting. Coatings can be made from various materials, including graphite, which offers a non-stick surface, and ceramic-based coatings that provide thermal insulation and prevent sand degradation from the heat of molten metal. Choosing the right coating is vital for ensuring optimal mold performance, reducing the risk of defects such as sand burn-on, and improving the quality of the casted component.

Stamping dies are categorized broadly into two types simple dies and compound dies. Simple dies perform one operation, such as cutting or bending, while compound dies can perform multiple operations simultaneously. This versatility allows manufacturers to produce complex shapes in a single step, thus enhancing productivity and reducing manufacturing time.

ทรายหล่อที่ใช้ในกระบวนการหล่อมีหลายชนิด แต่โดยทั่วไปสามารถแบ่งออกเป็น 3 ประเภทหลัก ได้แก่ ทรายซิลิกา (Silica Sand), ทรายเซรามิก (Ceramic Sand) และทรายโซดา (Sodium Sand) แต่ละประเภทมีคุณสมบัติที่แตกต่างกันไป ซึ่งทำให้เหมาะสมกับการใช้งานในแต่ละประเภทของการหล่อ
