Corn Cob Grit 16 mesh

Why Choose Corn Cob Grit for Blasting?

Corn cob grit is a natural, biodegradable abrasive derived from the woody ring of the corn cob. It is processed, crushed, and screened to produce a granular media with a hardness of approximately 4.0–4.5 on the Mohs scale. This low hardness makes it ideal for applications where substrate integrity is paramount. Unlike glass bead or aluminum oxide, corn cob grit absorbs oils and greases while gently scouring away surface deposits, leaving a clean, dry, and polished surface without pitting or etching.

Industrial Applications for 16 Mesh Grit

The 16 mesh particle size offers an optimal balance between aggressive cleaning action and fine surface finish. It is coarse enough to remove stubborn mold release agents, light carbon deposits, and paint overspray, yet fine enough to preserve polished mold cavities and precision components. Key applications include:

• Mold and Die Cleaning: Safely removes built-up residues from injection molds, rubber molds, and die-casting tools without damaging critical edges or surface polish.
• Surface Preparation: Prepares metal, plastic, and composite surfaces for bonding, coating, or painting by creating a clean, lightly textured profile.
• Deburring and Deflashing: Removes light burrs and flash from machined plastic and soft metal parts without altering part geometry.
• Parts Drying and Polishing: Used in vibratory finishing and tumbling operations to dry and polish small components after aqueous cleaning processes.

Handling and Process Recommendations

Corn Cob Grit 16 mesh is typically used in suction-fed or direct-pressure dry blasting cabinets. It can also be used in wheel blast systems for specific non-aggressive applications. For optimal results, maintain a blasting pressure between 2–4 bar (30–60 PSI). The media is highly recyclable; typical usage allows for multiple passes before the particles break down and become too fine. Ensure your dust collection system is adequate, as the organic dust generated is combustible and requires proper handling.
