Walnut Shell 20 mesh

Why Walnut Shell 20 Mesh?

Walnut shell abrasives are derived from crushed walnut shells, offering a biodegradable, non-toxic, and silica-free alternative to traditional mineral grits. The 20 mesh particle size provides an optimal balance between cleaning speed and surface finish, making it suitable for a wide range of industrial blasting operations.

This grade is particularly effective for removing carbon deposits, paint, and light coatings from molds, dies, and precision parts. Its angular shape ensures efficient cutting action, while the low hardness protects parent materials from pitting or warping.

Industrial Applications

• Automotive and Aerospace: Cleaning engine components, turbine blades, and transmission parts without dimensional change.
• Plastics and Rubber Molds: Removing residue and buildup from injection molds and extrusion dies.
• Electronics: Deflashing circuit boards and cleaning delicate connectors.
• General Maintenance: Degreasing and surface prep prior to re-coating or bonding.

Selection and Handling

For optimal results, Walnut Shell 20 mesh is typically used in suction or pressure blast cabinets at moderate air pressures (40–80 PSI). It is compatible with both dry blasting and some wet blasting systems. Due to its organic nature, it generates less dust than mineral abrasives and can often be recycled multiple times before breakdown, depending on application pressure and substrate hardness.

Proper moisture control during storage is essential to maintain flowability. SPA2Z offers guidance on pack sizing and equipment compatibility to help you integrate this media into your existing process.
