Walnut Shell 220 mesh

Why Choose Walnut Shell 220 Mesh?

Selecting the right abrasive is critical for achieving a flawless surface finish without damaging the workpiece. Walnut Shell 220 mesh offers a unique combination of hardness and friability. Its angular particles provide effective cleaning action, yet it is soft enough to be safely used on soft metals, plastics, composites, and even electronic components. This eliminates the risk of embedding or dimensional changes common with harder mineral or metallic abrasives.

The 220 mesh size is a fine grade, ideal for applications requiring a smooth, satin-like finish. It is commonly used in air-blast systems, either suction or direct pressure, and can be recycled multiple times under correct operating conditions, offering excellent media longevity and cost-effectiveness.

Key Industrial Applications

This versatile organic abrasive is trusted across a wide range of industries for its gentle cleaning action. Common applications include:

• Automotive & Aerospace: Cleaning pistons, valves, turbine blades, and composite panels without causing stress risers or surface damage.
• Electronics & Mold Making: Deflashing delicate electronic connectors and cleaning injection molds without altering mold geometry or surface polish.
• Restoration & Heritage: Safely stripping paint and grime from wood, fiberglass, and soft historical metals where preserving the original surface is paramount.
• General Maintenance: Removing carbon, varnish, and light oxides from precision parts in a workshop environment.

Handling and Selection Guidance

To maximize the performance and lifespan of Walnut Shell 220 mesh, proper handling and process setup are essential. Start with a lower blast pressure (typically 2–4 bar / 30–60 PSI) and increase only as needed to prevent premature media breakdown. Ensure your compressed air system is completely dry and free of oil to avoid clogging and contamination. The media can be screened and reused several times; a dust collection system will help maintain a clean working environment and consistent finish quality.
