OEM Steel Shot Blasting Equipment Product & Products

While both processes utilize high-velocity projectile media, their engineering objectives diverge fundamentally. Steel shot blasting is primarily a surface-finishing and cleaning operation designed to strip oxides, mill scale, and coatings, producing a specific anchor profile ($Ra/Rz$) for mechanical interlocking with protective paints. Controlled shot peening is a cold-working metallurgical process. Its sole purpose is to convert surface tensile stresses into an engineered compressive residual stress profile, delaying fatigue crack initiation and extending mechanical service life. Peening is qualified via Almen intensity (SAE J442/J443) and microscopic coverage percentages, whereas blasting is evaluated by surface cleanliness (ISO 8501-1 / SSPC).

KOSHIN systems are configured to meet rigorous international aerospace and industrial standards. Our shot peening cells comply with SAE AMS 2430 (General Shot Peening) and SAE AMS 2432 (Computer-Monitored Shot Peening). For airframe applications, our peen forming equipment meets Boeing BAC 5730 and Airbus AIPS requirements. Dust containment systems are built to CE Machinery Directive 2006/42/EC, ATEX Directive 2014/34/EU, and NFPA 68/69 combustible dust standards.

Through our dedicated application engineering center and laboratory testing services, customers can send representative workpieces or test coupons before freezing capital equipment designs. We utilize laboratory multi-axis robotic machines to map Almen saturation curves, perform coverage optimization studies, and verify residual stress profiles via X-ray diffraction (XRD). Once optimal media velocity, impingement angles, and cycle durations are validated, the parameters are locked directly into the production machine's PLC recipe architecture.

To expedite an engineering proposal, we request: (1) Workpiece 3D CAD models, material grades, and heat treatment condition; (2) Governing quality specifications (e.g., AMS 2430, ISO 8501-1); (3) Target zones requiring treatment vs. zones requiring masking; (4) Required Almen intensity envelope and coverage percentage; (5) Desired media class (cast steel shot S-series, conditioned cut wire CCW, ceramic microspheres); (6) Planned parts-per-hour production throughput; and (7) Facility footprint, available electric power supply, and compressed air CFM capacity.

When processing both ferrous alloys and stainless steel or titanium parts in proximity, cross-contamination leads to galvanic corrosion. KOSHIN addresses this by supplying stainless steel blast cabinets lined with non-contaminating polyurethane or manganese liners, isolated recovery hoppers, and dual-classification media systems. For multi-media operations, quick-purge pneumatic recovery loops and modular quick-swap hopper silos enable complete media changeover in less than 30 minutes without cross-contamination.

KOSHIN integrates reverse-pulse cartridge dust collectors fitted with PTFE membrane flame-retardant nanofiber media. Differential pressure transducers continuously log filter loading across the pleats. When differential pressure thresholds are reached, compressed air pulses dislodge cake dust into hermetically sealed disposal drums without interrupting production. Filtered exhaust air maintains particulate concentrations below 1.0 mg/m³, permitting indoor air recirculation or compliant exterior discharge under OSHA and EU environmental limits.
