Shell cores

Shell cores are precision sand cores produced using the shell molding process, where resin-coated fine sand is heated in a metal core box to form a thin, rigid shell. This method provides excellent dimensional accuracy, smooth surface finish, and high strength, making shell cores ideal for creating complex internal cavities in metal castings.

These cores are widely used in automotive, engineering, pump, valve, and industrial applications due to their consistency and reliability. Shell cores help reduce casting defects, improve overall casting quality, and support high-volume production while allowing easy removal after solidification.

Key Advantages

• High dimensional accuracy and excellent surface finish

• Strong and rigid structure during metal pouring

• Thin-wall cores with complex internal shapes

• Reduced casting defects and improved consistency

• Good collapsibility for easy core removal

• Suitable for high-volume production

• Enhanced productivity and reduced machining requirements
