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.

Enterprise Procurement: Mitigating Qualification Risk

How Tier-1 engineering procurement directors systematically evaluate bench top blast suppliers to ensure multi-year operational uptime and regulatory peace of mind.

Nadcap & AMS Specification Compliance

In aerospace surface preparation and shot peening, non-compliant equipment causes process non-conformances (NCRs). KOSHIN systems feature pre-configured mounting blocks for Almen strip verification (SAE J442/J443), calibrated pneumatic regulators, and exportable logging architectures to sail through Nadcap audits.

Total Cost of Ownership (TCO) Assessment

Low-grade blast cabinets suffer from abrasive wear at elbows, sight-glass etching, and frequent motor burnout. KOSHIN bench top systems incorporate polyurethane-lined cyclone separators, quick-change sacrificial window films, and heavy-duty dust collectors designed for continuous multi-shift production.

FAQ & Engineering Consultation

Frequently Asked Technical Questions

Detailed insights from our Singapore engineering and application support team.

What is the primary difference between standard sand blasting and controlled shot peening?

Sand and abrasive blasting are material removal processes intended for descaling, deburring, and surface profiling. In contrast, shot peening is a tightly regulated cold-working process that bombards the surface with spherical media to introduce compressive residual stress layers, verified via Almen intensity (SAE J442) and coverage percentage.

Can KOSHIN custom bench top blast cabinets handle aggressive abrasives like aluminum oxide or silicon carbide?

Yes. Every custom benchtop cabinet can be configured with wear-resistant boron carbide nozzles, sacrificial rubber wall linings, and heavy-gauge stainless steel construction to withstand continuous cycling of aggressive media without degrading chamber integrity.

How does the cabinet ensure compliance with cleanroom or laboratory dust standards?

Our systems feature sealed negative-pressure air circulation integrated with cartridge dust extractors and secondary HEPA filtration. This guarantees sub-micron particulate filtration efficiency (99.97% @ 0.3μm), preventing fugitive dust emissions into precision lab spaces.

Can you provide trial processing on our sample workpieces prior to contract confirmation?

Yes. Through our Singapore R&D headquarters and laboratory testing facilities, we run empirical trials, generate saturation curves, evaluate surface roughness, and establish optimized parameters before releasing production hardware.
