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.

Local Industrial Ecosystem

Precision Surface Treatment Landscape in Ho Chi Minh City & Southern Vietnam

As Southern Vietnam transitions from light assembly to high-precision engineering, local manufacturers in Ho Chi Minh City, Binh Duong, and Dong Nai face strict fatigue standards for aerospace, medical implants, and high-spec automotive exports.

Aerospace Tier-1 & Tier-2 Supply Chains

With aerospace manufacturing hubs expanding near Tan Son Nhat and the upcoming Long Thanh International Airport, structural parts, nacelles, and turbine hardware require strict compliance with AMS 2430 and AMS 2432 specifications. KOSHIN experiment services enable local suppliers to validate Almen intensity saturation curves before procurement.

Medical Device & Titanium Implants

In Saigon Hi-Tech Park (SHTP), medical instrument and orthopedic implant manufacturers utilize controlled microsphere peening to eliminate surface micro-cracks and induce biocompatible residual stresses on Ti-6Al-4V bone screws, dental fixtures, and artificial joint assemblies without excessive roughness.

High-Stress Automotive Transmission Gears

Automotive and e-mobility gear plants in Binh Duong require controlled shot peening to prevent bending fatigue failure at tooth root fillets. KOSHIN contract processing provides multi-nozzle robotic peening to yield uniform coverage and high compressive residual stress across complex gear geometries.

Technical FAQ & Buyer Knowledgebase

Frequently Asked Questions: Contract Peening & Lab Testing

Comprehensive answers addressing Nadcap audit readiness, metallurgical verification, logistics turnaround, and equipment retrofitting for Ho Chi Minh City enterprises.

How does KOSHIN assist Ho Chi Minh City manufacturers with Nadcap accreditation?

Nadcap AC7117 audit compliance requires rigorous proof that every operational parameter is tightly governed and recorded. KOSHIN experiment services provide complete data sets including automated Almen strip saturation curves (conforming to SAE J442 and SAE J443), computerized air pressure curves, continuous media mass flow logging, and media size/shape roundness reports according to AMS 2430 and AMS 2432 standards. This complete documentation package can be integrated directly into your First Article Inspection (FAI) reports and audit dossiers.

Can we conduct trial shot peening before committing to equipment capital expenditure?

Yes. Our experimental laboratory runs pre-procurement validation trials on your specific workpieces. We develop customized tooling fixtures, map out robotic motion programs, verify depth of compressive residual stress via X-ray diffraction (XRD) partners, and supply complete Almen strip test cards. Once the procedure is locked, the exact recipe parameters are transferred directly to your newly manufactured production unit.

What are the logistics procedures for shipping batch parts from Vietnam to the processing center?

For specialized contract processing and pilot runs, components are consolidated via standard air freight (Tan Son Nhat SGN) or fast sea freight (Cat Lai / Cai Mep). We supply protective packaging guidelines and anti-corrosion VCI barrier protocols to guarantee parts arrive uncontaminated. Upon completion of processing and visual UV coverage verification, components are resealed, certified with Certificates of Conformity (CoC), and dispatched back under bonded customs clearance.

What is the technical difference between standard abrasive blasting and controlled shot peening?

Abrasive sand blasting uses angular particles (such as aluminium oxide or garnet) designed to etch, descale, or strip coatings by cutting away microscopic material layers. In sharp contrast, controlled shot peening utilizes spherical, high-hardness media (cut wire, cast steel, ceramic beads, or glass microspheres) propelled under precisely measured pressures to deform the surface plastically. This cold-working process leaves a permanent residual compressive stress layer, arresting crack initiation and dramatically extending the cyclic fatigue life of safety-critical parts.

How are media size and shape roundness controlled during long production runs?

Our automated machines incorporate multi-stage media classification units featuring vibratory screen sieves to eliminate undersized particles and spiral separators to discard broken or non-round shot. This ensures the peening stream adheres continuously to AMS specifications, eliminating sharp-edged fragments that could create stress concentration notches on parts.
