Custom Experiment & Contract Processing Services Serving Uzbekistan

While shot blasting is primarily an aggressive cleaning and surface-preparation mechanism engineered to remove mill scale, corrosion, or previous coatings and generate an anchor profile (Ra) for painting, controlled shot peening is an exact metallurgical cold-working science. Shot peening utilizes spherical, conditioned media impacted under calibrated velocity to create overlapping hemispherical indentations. This plastically deforms the outer surface layer in tension while inducing a stable, beneficial zone of compressive residual stress beneath it. This subsurface compressive layer acts as a mechanical barrier that prevents fatigue crack nucleation, halts stress corrosion cracking, and substantially extends the high-cycle fatigue life of critical components. Peening quality is controlled and verified via Almen intensity and percentage coverage, not visual cleanliness.

We provide full, turnkey technology transfer. Through our custom experiment services, Uzbek clients send component samples and specifications to our testing laboratories. Our senior application engineers perform multi-exposure trials using calibrated Almen strips mounted on representative fixtures, plotting the exact arc height against exposure duration to pinpoint the true mathematical saturation point (the Almen saturation knee, where doubling time yields less than a 10% increase in arc height per SAE J443). Once determined, we provide a complete Validation Dossier detailing required nozzle sizes, pressures, angles, turntable RPMs, and media specs. When delivering a machine to Uzbekistan, our engineers configure these validated recipes into the system PLC and train your technicians to perform standard daily Almen strip verification tests.

Yes. Many manufacturing and MRO enterprises in Tashkent and the Navoi FIZ utilize our contract processing services to avoid early CapEx outlays. We can process trial runs, prototype units, or scheduled production batches directly at our state-of-the-art toll manufacturing cells. Each processed batch is delivered with full quality documentation, including Almen saturation logs, coverage verification reports, sieve breakdown certificates, and optional XRD residual stress depth analyses. Once production volumes warrant in-house machinery, the exact recipe developed during contract processing is directly transferred into your customized KOSHIN production cell.

Capital equipment, replacement spares, and test batches travel via well-established direct rail and multimodal road freight corridors along the Belt and Road infrastructure. Standard shipments depart from our assembly hubs in China, clear customs via the Khorgos/Altynkol land port on the Kazakh border, and arrive at bonded logistics terminals in Tashkent (such as Chukursay) or directly to the Navoi Free Industrial Zone. Standard transit times by expedited direct road transport are approximately 10 to 14 days, with full customs documentation, international CMR consignment notes, and transit insurance included.

Media selection is governed by substrate hardness and application callouts. For heavy-duty mining and metallurgical machinery (e.g., AMMC/NMMC crusher shafts and mill pinions), high-hardness cast steel shot (SAE J827) or conditioned cut wire (AMS 2431/3 or /8) is typically recommended to induce deep compressive residual stress layers down to 0.4–0.8 mm. For aerospace alloys, titanium blisks, thin-walled aircraft skins, and landing gear assemblies (e.g., Uzbekistan Airways Technics applications), we specify round ceramic beads (Zirshot per AMS 2431/7) or high-sphericity glass beads (AMS 2431/1). Ceramic media generates high kinetic energy transfer with lower surface roughness and zero iron-contamination risks on non-ferrous substrates.

KOSHIN provides comprehensive lifecycle warranties across all equipment delivered to Uzbekistan. Our industrial automation systems feature secure industrial VPN/Profinet gateways for real-time remote diagnostics directly from our engineering team in Singapore, allowing instant PLC logic troubleshooting, recipe adjustments, and sensor checks. For physical maintenance, preventative servicing, and operator retraining, our factory-trained field service engineers travel on-site to your facility in Uzbekistan. Essential consumable items—such as boron carbide nozzles, Almen strips, Almen gauges, rotary air seals, and dust collector filter cartridges—are dispatched rapidly to ensure zero downtime.
