High-Quality Peen Forming Factory & Pricelist Serving Korea

Conventional brake or press forming forces aluminum plates into metal dies, creating high localized tensile stresses on the convex side that make the component susceptible to stress corrosion cracking (SCC) and premature fatigue failure. Peen forming is a purely cold-working impact process. High-velocity spherical media (such as cast steel shot CCW or conditioned cut wire) stretches the surface layer through localized plastic deformation. Because the underlying elastic core restrains this expansion, a high-magnitude compressive residual stress layer is generated, naturally bending the workpiece into the desired aerodynamic curvature without dies, springback issues, or tensile fatigue risks.

Yes. Every automated peen forming and shot peening system manufactured by KOSHIN for aerospace applications complies strictly with SAE AMS 2432 (Computer Monitored Shot Peening) and Nadcap AC7117 audit criteria. The digital architecture monitors, controls, and continuously logs all critical process variables: media mass flow rate (via electronic Magna-Valves), blast nozzle air pressure, multi-axis gantry or robotic traverse speeds, target standoff distances, and impact angles. If any monitored variable deviates beyond ±2% of authorized recipe limits, the automated interlock pauses the cycle instantly to prevent non-conforming parts.

Standard robotic shot peening cells typically require 10 to 14 weeks for design, build, and internal FAT run-off at our integrated China production base. Large-format CNC wing skin peen forming gantry machines require approximately 16 to 22 weeks. Finished machinery is packed in export-grade vacuum moisture barrier crates and shipped via direct roll-on/roll-off or container vessels from Shanghai or Qingdao port directly to Busan New Port (Pusan) within 48 to 72 hours transit time, minimizing supply chain vulnerabilities.

All equipment destined for Korean customers is configured to 380V/440V 3-Phase 60Hz industrial electrical requirements. Safety interlocks, category-4 light curtains, e-stops, and pressure vessels conform to KOSHA (Korea Occupational Safety and Health Agency) mandates. User interfaces (HMI) on our Siemens / Beckhoff / Mitsubishi control systems are fully translated into Korean and English, and documentation includes complete electrical schematics, Korean-language maintenance manuals, and localized safety certificates.

Absolutely. Through KOSHIN's experiment and contract processing lab services, prospective clients can supply raw material test coupons (such as 7050-T7451, 2024-T351, or Titanium Ti-6Al-4V). We establish precise Almen saturation curves (SAE J443), analyze arc height profiles, generate X-ray diffraction (XRD) sub-surface compressive stress profiles, and optimize forming radii. The resulting process parameters are locked directly into the CNC recipe delivered with your production machine.
