Custom Steel Plate Shot Blasting Machine Factory & Factories

Shot blasting and sand blasting remove surface contaminants such as mill scale, oxidation, and rust, producing a mechanical anchor pattern for protective coatings. In contrast, shot peening is a tightly monitored cold-working technique using spherical media to induce controlled compressive residual stresses to combat fatigue failure. Peening is governed by Almen saturation curves and coverage, whereas plate blasting is governed by cleanliness classifications (ISO 8501-1 / SSPC-SP10) and surface roughness values (Rz/Ra).

KOSHIN systems are engineered around customer and industry criteria. For heavy fabrication and marine plates, systems conform to ISO 8501-1 (Sa 2.5, Sa 3) and SSPC/NACE standards. For high-precision and aerospace applications, equipment satisfies AMS 2430, AMS 2432 (computer-monitored peening), SAE J442, SAE J443, and Nadcap audit traceability standards.

Yes. KOSHIN maintains comprehensive pilot testing laboratories. Customers can submit material samples to determine optimal abrasive media selection, verify feed speeds, measure surface roughness (Ra/Rz), or establish Almen saturation curves. These parameters are converted into locked digital recipes for your production machine prior to sign-off.

We require plate width, minimum and maximum plate thickness, plate length, material grade, initial surface condition (grade A, B, or C rust), target cleanliness (Sa 2.5/Sa 3), required line feed rate (m/min), dust collector emission standards, and factory footprint/overhead crane limitations.

All equipment undergoes comprehensive pre-assembly and full FAT trial runs at our integrated manufacturing plant in China before shipment. Field engineering teams coordinate directly from Singapore to manage on-site installation, SAT commissioning, and operator qualification in over 50 countries, with ongoing lifecycle supply of high-wear replacement components.
