Specialized Surface Treatment Systems
Engineered by KOSHIN Precision Pte. Ltd. for mission-critical aerospace, turbine, and automotive components requiring rigorous process control.
Evolution of Automated Sandblasting & Surface Engineering
From manual pneumatic blast cabinets to continuous multi-axis robotic processing, industrial surface conditioning has evolved into an exact digital discipline governed by strict metallurgical specifications.
Aerospace Flight Readiness
Rotating compressor discs, fan blades, landing gear cylinders, and high-pressure turbine components operate under acute dynamic load and cyclic fatigue. Automated shot peening and specialized abrasive finishing induce compressive residual stress profiles that inhibit micro-crack propagation, directly increasing the certified Mean Time Between Unscheduled Removals (MTBUR).
Automotive E-Mobility Shifts
Electric vehicle (EV) drivelines demand ultra-compact planetary gearboxes spinning above 18,000 RPM. These assemblies present extreme contact-stress profiles. High-reproducibility automated shot blasting and microsphere peening reduce root-bending stress, refine tooth flanks to low micron Ra finishes, and eliminate high-frequency gear whine.
Medical Device Integrity
Implantable orthopaedic components—such as femoral hip stems and spinal cages—rely on biocompatible abrasive micro-blasting to establish exact Ra and Rz micro-textures. This controlled roughness promotes rapid osteointegration while ensuring zero metallurgical cross-contamination occurs during mass production.
Digital Governance Under AMS 2430 & AMS 2432 Specifications
Unlike general cleaning systems, high-integrity automated sandblasting and shot peening systems must maintain absolute physical accountability over blast pressure, mass media flow, and tool trajectory.

Traceable Cycle Logging Compatible with Nadcap AC7117 Auditing Standards
The Physics of Controlled Impact
When an automated blast stream strikes a metallic substrate, the kinetic energy transfer creates plastic deformation in the outer surface layers, counterbalanced by an elastic recovery force beneath. The result is a robust zone of residual compressive stress. KOSHIN Precision Pte. Ltd. designs systems that eliminate traditional human variables. By pairing precise Almen saturation curve analysis (SAE J442/J443) with digital MagnaValve media metering, spiral media separators, and multi-deck vibratory classification screens, our systems maintain media integrity, size uniformities, and impact velocities over hundreds of operating cycles.
Macro Solutions Across Core Industrial Verticals
Turnkey engineering architectures tailored to the stringent cycle, dimensional, and environmental needs of world-class facilities.
Propulsion & Aerostructures
Integrated multi-station automated sandblasting and peening cells handle complex geometries such as fan disk dovetail slots, blisks, and large wing-skin alloy panels. Dieless aerodynamic peen forming shapes structural wing panels while embedding stress layers that mitigate stress corrosion cracking (SCC).
High-Duty Automotive & Commercial Fleets
High-throughput automated rotary indexing tables blast engine connecting rods, transmission gears, differential ring gears, and heavy suspension coils. Dual-robot configurations allow non-stop loading and simultaneous blast coverage, cutting standard unit cycle times by up to 60% compared to legacy blast units.
Global Energy, Oil & Gas Infrastructure
Specialized internal lance and rotary blast tools process downhole drill collars, riser casing threads, and industrial power generation gas turbine buckets. Surface micro-etching guarantees thermal spray barrier coating (TBC) adhesion under harsh corrosive and thermal cycling operations.

Frequently Asked Questions by Industrial Buyers & Engineers
Key technical and procurement criteria regarding blast automation, machine validation, and Nadcap regulatory compliance.
What is the fundamental difference between automated sandblasting and shot peening?
Automated sandblasting (abrasive blasting) is primarily designed to remove surface contaminants, mill scale, rust, and thermal coating layers, or to prepare a controlled micro-roughness profile for subsequent bonding and coating. In contrast, shot peening uses spherical, non-abrasive media (such as conditioned cut wire, cast steel shot, or ceramic beads) to plastically deform the substrate and induce a layer of beneficial compressive residual stress. While blasting cleans or etches, shot peening enhances fatigue life, resistance to fretting, and stress-corrosion cracking protection.
How does KOSHIN equipment ensure Nadcap AC7117 audit compliance?
KOSHIN systems comply with strict AMS 2432 / Nadcap computer-monitored peening criteria through continuous feedback loops. The system dynamically monitors and logs blast pressure, media flow rate, nozzle standoff distance, gun traverse speed, and part rotational velocity. If any parameter drifts outside approved tolerance limits, an automated alarm interlock pauses the cycle instantly to prevent under-peening or over-peening of flight-critical workpieces.
Can KOSHIN run pre-purchase trials and saturation curve validation on our parts?
Yes. KOSHIN operates fully instrumented testing labs at its Singapore engineering center and production facilities. We conduct comprehensive Almen saturation curve developments (SAE J443), optical coverage studies, and residual stress depth profiling on customer-supplied components. These validated machine recipes are directly ported to your factory system prior to delivery.
What engineering information is needed for a customized technical equipment proposal?
To provide an accurate technical configuration, our team requires part dimensions and weights, 2D/3D component drawings highlighting target surface treatment zones, required cycle times (units per shift), specified Almen intensity ranges and coverage requirements, preferred media type and size, available factory footprint, and facility electrical/pneumatic utility capacity.
What after-sales, commissioning, and spare parts support is available overseas?
KOSHIN supports installations across more than 50 countries. Our international field service teams provide comprehensive on-site installation, factory commissioning, operator maintenance training, and calibration services. Furthermore, our systems feature remote industrial IoT diagnostics, and standard wear components (nozzles, blast hoses, liners, valves) are stocked at regional logistics hubs for rapid dispatch.
