Hydraulic Media Cushioning

Unlike dry mechanical blasting where media impact generates high thermal spikes and particle imbedment, wet slurry blasting introduces a water boundary layer that cushions the micro-collision. This prevents abrasive particle embedding on critical superalloys such as Inconel 718 and Titanium Ti-6Al-4V while preserving surface chemical purity.

Micro-Roughness & Ra Preservation

Components subjected to continuous cyclic fatigue, including turbofan disc slots and blisk roots, demand tight surface roughness tolerances. Slurry systems deliver homogeneous surface conditioning with Ra values controllable down to sub-micron scales, eliminating downstream polishing stages and post-process metallurgical rework.

Closed-Loop Concentration Governance

Consistent Almen saturation relies heavily on homogeneous slurry density. KOSHIN systems incorporate real-time vortex separation, concentration ultrasonic monitoring, and automatic media top-up loops, eliminating drift in kinetic impingement energy throughout multi-shift production cycles.

Industrial Deployments

Engineered for High-Stress Industrial Operating Environments

Detailed technical application workflows where wet slurry and precision shot peening equipment form the critical barrier against mechanical fatigue, fretting, and corrosion cracking.

Commercial Aviation Turbines & Blisks

Deploying dual-robot slurry peening ensures simultaneous front-and-back face coverage on integrally bladed rotors (Blisks). The continuous fluid wash suppresses abrasive dust buildup inside narrow blade root channels, maintaining the critical compressive residual stress layer specified by propulsion OEMs.

Heavy Landing Gear Assemblies

High-strength steel alloys (300M, AerMet 100) are particularly susceptible to hydrogen embrittlement and micro-notch defects during abrasive prep. Controlled slurry blasting gently cleans heat treatment scale while preparing surfaces for cadmium or zinc-nickel electroplating without localized micro-cracking.

Automotive Precision Transmissions & EV Pinions

In electric drivetrains, high rotational speeds demand super-quiet gear tooth profiles. Slurry peening delivers tooth root compressive residual stresses exceeding -900 MPa while refining the flank surface contact plateau, dramatically cutting decibel emissions and extending tooth contact life.

Technical & Commercial Clarifications

Engineering Inquiries & Procurement FAQ

Everything your technical evaluation panel needs to verify prior to specifying KOSHIN wet slurry or robotic peening cells.

What is the fundamental difference between dry shot peening and wet slurry blasting?

Dry shot peening accelerates dry media using compressed air or centrifugal wheels to induce plastic deformation. While effective for compressive residual stress, it generates fine dust, risks media fracture imbedment, and increases surface roughness. Wet slurry blasting suspends fine abrasive media in a water matrix, creating a fluid cushion upon contact. This enables lower surface roughness (Ra), dust-free operation, no abrasive contamination, and excellent application stability for thin-wall components.

Which aerospace industry specifications are KOSHIN machines configured to comply with?

Our slurry blasting and shot peening machinery are architected to support AMS 2430, AMS 2432 (computer-monitored peening), SAE J442, SAE J443 (Almen test procedures), and customer-specific Boeing, Airbus, or GE internal specifications. Closed-loop process loggers record blast pressures, axis kinematics, media flows, and slurry temperatures directly into tamper-evident batch logs suitable for Nadcap audits.

Can we conduct trial runs on our engineering samples prior to purchasing machinery?

Yes. KOSHIN maintains comprehensive test cells in Singapore and China equipped with contract processing and R&D stations. Our materials team generates full Almen saturation curves, verifies X-ray diffraction (XRD) residual stress depth profiles, and confirms Ra finishes on your sample parts before machine layout freeze.

What engineering variables must be submitted to obtain an accurate quote?

To deliver an optimized proposal, provide: 1) Part CAD geometries and dimensions, 2) Base alloy type and hardness, 3) Specified Almen intensity target and required coverage percentage, 4) Desired Ra surface profile, 5) Hourly production rate, and 6) Plant facility restrictions (ceiling clearance, power availability, closed-loop wastewater parameters).

How does KOSHIN guarantee long-term overseas service and support?

We deploy factory-trained field service engineers for on-site anchoring, installation, SAT run-offs, and operator qualification. Lifecycle support is backed by regional inventory centers stocking high-wear polyurethane conduits, boron nozzles, and PLC spares, accessible through dedicated technical support helplines across over 50 countries.
