OEM Metal Shot Blasting Machine Supplier & High-Precision Systems

Shot blasting is primarily a material-removal and cleaning process intended to remove mill scale, oxidation, and contaminants to create a specific surface roughness (Ra profile) prior to coating or bonding. In contrast, shot peening is a tightly regulated cold-working process where spherical media impacts impart beneficial compressive residual stresses on surface and sub-surface layers. Peening performance is validated via Almen strip deflection arcs (SAE J442/J443) and optical coverage verification, rather than visual cleanliness grades.

Our systems are specifically customized to satisfy AMS 2430 (manual/automated shot peening), AMS 2432 (computer-monitored peening), SAE J442, SAE J443, and Nadcap AC7117 audit criteria. For blast cleaning and protective painting prep, our machines conform to ISO 8501-1 (Sa 2.5, Sa 3) and SSPC/NACE surface cleanliness metrics, with electrical systems conforming to CE Directives, UL 508A, and NFPA standards.

Yes. KOSHIN maintains comprehensive in-house trial and lab testing facilities. Customers supply representative raw workpieces to establish Almen saturation curves, verify coverage time windows, evaluate residual stress depth profiles using X-ray diffraction (XRD), and freeze CNC nozzle programs. Validated parameter matrices are then transferred directly into the PLC software of your custom production machine.

To provide an accurate technical configuration, our application engineers require: (1) Workpiece 3D CAD models/drawings with defined target treatment zones, (2) Base alloy metallurgy and heat treat state, (3) Required Almen intensity range (e.g., 0.008-0.012A) and coverage target (e.g., 100% or 200%), (4) Media specification (cast steel, ceramic beads, glass beads, or conditioned cut wire), (5) Production throughput demands (cycle time per unit), and (6) Available facility footprint, ceiling height, and electrical/pneumatic utility capacity.

Operating from our Singapore engineering headquarters and integrated production facilities, we deliver comprehensive global commissioning. Our certified engineers handle on-site mechanical alignment, electrical integration, and SAT sign-off, alongside structured classroom and hands-on maintenance training. Critical wear components (carbide nozzles, blast wheel blades, liners, and precision Magnavalves) are stocked for rapid international dispatch.
