Bead blasting helps to achieve uniform surface finishes without affecting the part’s dimensions. Also, it works perfectly with a wide range of materials, making it suitable for various industries. Manufacturers use bead blast surface finish to enhance the durability of components.

This finishing process is flexible, and it fits into an extensive array of manufacturing processes. For instance, smaller beads help with lighter processes that require finely detailed works. On the other hand, medium-size beads are the best choice when dealing with metal materials like stainless steel and aluminum. They are popular for their ability to hide defects on components surfaces. Larger beads are perfect for deburring and cleaning rough surfaces on metal castings and automotive parts.
