ODM Wet Sandblasting Equipment Pricelist & Product Solutions

In dry blasting, dry impact forces embed sharp shattered abrasive particles directly into softer metal matrices (such as titanium, aluminum, or nickel alloys), creating stress-risers and contamination. In wet blasting, the abrasive particle is surrounded by a liquid boundary layer. Water acts as a hydrodynamic cushion during impact; while the abrasive still deforms and polishes the microscopic peaks of the metal, the continuous liquid flush prevents particulate embedding and washes away fractured fines instantly.

KOSHIN utilizes heavy hot-cast polyurethane linings (minimum 6mm to 12mm thickness) applied over 304/316L stainless steel hulls. Under continuous two-shift production using aluminum oxide or glass bead slurries, our proprietary vortex pump impellers and polyurethane-lined blast chambers routinely achieve between 4,000 and 7,500 operational hours before refurbishment. Routine wear parts, such as boron carbide blast nozzles, maintain internal bore integrity for 600 to 1,200 continuous blasting hours.

While dual-purpose machines can be engineered using multi-tank configurations, optimal results are achieved when media slurries match the target process. Controlled wet shot peening requires spherical media (conditioned cut wire, cast steel, or high-hardness ceramic beads) monitored via Almen intensity curves, whereas cosmetic finishing utilizes fine glass beads or white fused alumina. KOSHIN manufactures twin-sump systems with automated flush sequences to switch media slurries without cross-contamination.

The closed-loop system routes spent slurry through a multi-stage hydrodynamic hydrocyclone that separates heavy intact abrasive from microscopic degraded fines. The overflow enters a dynamic paper band micro-filter and settling weir, followed by optional carbon filtration and UV sterilization. The recovered deionized water is continuously re-injected into rinse manifolds and slurry reconstitution tanks, achieving zero environmental sewer discharge and reducing water consumption by over 95%.

Every aerospace-grade unit is supplied with complete qualification packages: Factory Acceptance Test (FAT) signoff logs, Site Acceptance Test (SAT) records, Calibration Certifications for pressure transducers and digital flow meters traceable to NIST, Almen saturation curve validation reports per SAE J443, software traceability architecture meeting AMS 2432 guidelines, and complete multi-tier user password protection structures.

Standard automated rotary machines maintain an 8-to-10 week delivery schedule. Complex engineered-to-order (ODM) cells featuring 6-axis articulated robotics, integrated vision alignment, closed-loop slurry density control, and custom tooling typically require 12 to 16 weeks from approved engineering drawings to complete factory run-off and FAT approval.
