OEM Surface Treatment Equipment Exporters & Company

Abrasive sand blasting is primarily an erosive, subtractive surface-preparation process designed to strip scale, remove oxidation, and etch an anchor profile for thermal coating or paint adhesion. Shot peening is a metallurgical, non-erosive cold-working process. Spherical media (cast steel, ceramic, or glass beads) strike the metal substrate within an elastic-plastic regime, creating overlapping microscopic dimples that induce subsurface compressive residual stresses. Its performance is verified through Almen strip saturation curves (SAE J442/J443) and residual stress depth profiles (via X-ray diffraction), rather than visual cleanliness.

KOSHIN automated shot peening centers integrate closed-loop feedback controls across every parameter defined in AMS 2432B. Mass media flow is continuously managed and monitored by calibrated MagnaValves or gravimetric dosing gates; blast pressures are governed by proportional valves with electronic transducers; and nozzle paths are driven by coordinated multi-axis Fanuc/ABB robotic arms or CNC linear gantries. Should any parameter deviate beyond the set tolerance window (e.g., ±5% media flow), the PLC triggers an automatic interlock abort and writes a fault event to an immutable electronic batch log.

Yes. Our Singapore Application & R&D Center features a fully equipped metallurgical testing laboratory and production-scale test rigs. We accept customer component samples, run Almen saturation curve iterations, verify target coverage (including fluorescent tracer dye inspections), and confirm residual stress profiles via XRD before finalizing the equipment specification. This preliminary verification eliminates qualification risk and allows pre-validated recipes to be loaded straight into your production machine PLC.

Wet shot peening suspends spherical media in a recirculated slurry of water and rust inhibitors. The liquid carrier creates a dampening effect that moderates surface roughness and prevents shot fragmentation, allowing fine ceramic or glass beads to peen thin-walled, high-value components (e.g., titanium turbine blades, surgical implants, precision valve springs) without micro-cracking or embedded dust residue. It also eliminates explosion hazards associated with fine reactive metal particulates.

Every machine undergoes a full dry-run and wet-run FAT at our production plant prior to export packing. The client or a third-party auditor inspects mechanical alignments, safety interlocks, pneumatic stability, and robot trajectory repeatability. We also run full Almen saturation test panels on site. Upon arrival at your facility, our international field service engineers manage positioning, leveling, wiring, utility hookup, SAT (Site Acceptance Testing), and hands-on maintenance and operator training.
