What is the difference between shot peening and shot blasting?

Shot blasting and sand blasting remove material such as scale, rust or old coatings and create a surface profile. Shot peening is a cold-working process that uses controlled media impacts to induce a layer of compressive residual stress, which slows crack initiation and extends fatigue life. Peening is verified by Almen intensity and coverage, not by visual cleanliness.

Which specifications can KOSHIN shot peening machines be configured for?

KOSHIN systems are configured around the customer's governing specification, typically aerospace standards such as AMS 2430 or AMS 2432 for computer-monitored peening, with Almen intensity verified per SAE J442 and J443 and media controlled to the applicable media specification. Monitoring and data records are designed to support Nadcap-audited processes.

Can KOSHIN run trials on our parts before we purchase a machine?

Yes. KOSHIN operates in-house machines for experiment services, including Almen saturation curves, coverage studies and process development on customer samples. Validated parameters are then transferred into the production machine recipe, and contract processing is available for production batches.

What information is needed to prepare a machine proposal?

Provide workpiece dimensions and material, peening area, intensity and coverage requirements, media type and size, required production rate, available floor space and height, and any HS&E, Nadcap, emissions, noise or energy-efficiency requirements.

Does KOSHIN support overseas installation and after-sales service?

KOSHIN supports customers in more than 50 countries and regions with installation, commissioning, operator training, spare parts and lifecycle upgrades, coordinated from its Singapore engineering center.

The KOSHIN Robotic Shot Peening Machine is a fully enclosed, automated blast cell engineered to induce controlled compressive residual stress on the surface of metal components, dramatically extending fatigue life and resistance to stress-corrosion cracking. A 6-axis industrial robot wields the nozzle along part-specific tool paths, while a satellite indexing turntable presents multiple workpieces in sequence — combining the surface-quality benefits of manual peening with the throughput and repeatability demanded by modern aerospace, automotive, and tooling supply chains.

Every cycle is recipe-driven from the integrated HMI/PLC, so pressure, nozzle stand-off, dwell time, and turntable speed are recalled per part number rather than re-set by hand. The closed-loop media recovery system continuously screens, classifies, and returns the working media, keeping intensity stable from the first shift of the day to the last. The result is a peening process you can qualify, audit, and scale.
