OEM Grit Blasting Equipment Quotes & Products

Grit blasting uses angular abrasives (aluminum oxide, chilled iron grit) primarily to remove surface contaminants, oxides, scale, or coatings, establishing an anchor profile (Ra) for bonding. Shot peening uses perfectly spherical media (cut wire, cast steel shot, ceramic beads) to bombard the metal, cold-working the surface to impart beneficial compressive residual stresses that retard fatigue cracking and stress corrosion without removing substrate material.

Our equipment is built to satisfy stringent international aerospace directives, including SAE AMS 2430 (manual/controlled shot peening), AMS 2432 (computer-monitored shot peening), SAE J442 / J443 for Almen strip verification and saturation curve generation, and Nadcap AC7117 audit criteria. Process logs capture real-time media flow, dynamic pressure, nozzle speed, and part RPM to guarantee compliance.

Yes. KOSHIN operates a dedicated laboratory testing center equipped with multi-axis automated machines. We run comprehensive trial batches on your supplied sample parts, developing verified Almen saturation curves, surface roughness profiles, and coverage mapping (100% to 200%). The proven recipes are directly locked into the CNC/PLC controller of your production machine prior to shipment.

To deliver a comprehensive engineering and commercial proposal, we request: 1) Workpiece drawings, material grade, dimensions, and weights; 2) Target treatment zones, required coverage percentage, and Almen intensity range (if peening); 3) Media type and size (e.g., CCW14, ceramic Z150, 120# corundum); 4) Target cycle time or daily production quota; 5) Facility floor plan and ceiling height constraints.

Wet shot peening suspends abrasive or spherical media in an aqueous slurry propelled by compressed air. The liquid dampens harsh impact extremes, yielding smoother surface finishes, drastically reducing media attrition rates, eliminating airborne dust, and preventing media impregnation into softer alloys. It is ideally suited for titanium surgical implants, fine aerospace gear teeth, and thin-gauge components.

KOSHIN provides comprehensive global field services across more than 50 countries. Our bilingual field engineers perform on-site mechanical anchoring, electrical interconnects, Site Acceptance Testing (SAT), and thorough operator/maintenance personnel certification. We maintain regional spare part hubs and offer 24/7 remote VPN diagnostic support for rapid issue resolution.
