Moreover, green sand casting plays a significant role in the production of industrial equipment, agricultural tools, and even artistic sculptures. Its adaptability and efficiency make it a preferred method for both high-volume production and custom parts.

The process begins with the selection of a suitable metal, which can vary from stainless steel, aluminum, brass, to copper, depending on the intended application. Once the right material is chosen, the next step is to create a die, which is a mold that defines the shape of the part to be stamped. This die is machined with extreme accuracy to ensure that the final product meets the required specifications.

2. Minimization of Defects Ejector pins help in preventing casting defects that can arise from parts being stuck in the die. By uniformly distributing the ejection force, ejector pins reduce the risk of surface damage and maintain the part's dimensional accuracy.

4. Continuous Improvements Gathering feedback from production runs can lead to continuous improvements. Analyzing bottlenecks or issues in part ejection can inform future design modifications for better draft angles.

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

Despite its many advantages, green sand casting does have some drawbacks. One of the main challenges is the potential for sand erosion, which can occur during the casting process. If the sand is not adequately prepared or maintained, it can lead to defects in the final product, such as blowholes, sand inclusions, or poor surface finish. This necessitates careful control of the sand mixture and regular quality checks.
