View SpecificationsEngineering Aluminium Surface Integrity: Beyond Visual Aesthetics
Aluminium alloys (2000, 6000, and 7000 series) exhibit distinctive physical attributes: low elastic modulus, pronounced chemical reactivity, and susceptibility to work-hardening anomalies. Standard mechanical blasting methodologies designed for ferrous metals cause surface micro-cracking and erratic residual stress fields. KOSHIN redefines industrial aluminium shot blasting as an audited, aerospace-grade thermodynamic and kinetic process.
Almen Saturation & Plastic Deformation
Unlike steel processing, controlled impact on ductile aluminium structures requires sub-surface compressive stress induction without micro-folding. We calibrate saturation curves per SAE J442 / SAE J443 specifications, utilizing lightweight media (ceramic beads, cut wire aluminium, and fine glass microspheres) to inhibit galvanic cross-contamination while locking uniform depth profiles.
Thermomechanical Stress Neutralization
Thin-walled aerospace aluminium profiles and lightweight EV battery enclosures suffer geometric distortion under asymmetric blast streams. KOSHIN's multi-axis robotic kinetic trajectory management counteracts localized heat dissipation and balances dual-sided kinetic vectors, maintaining volumetric tolerances within ±0.05 mm across structural parts exceeding 3 meters.
Nadcap Audit-Ready Digital Governance
Compliant with AMS 2430 and AMS 2432 guidelines for computer-monitored shot peening, every machine records digital operational parameters—air propellant pressure, mass flow rate, rotational velocity, and acoustic nozzle sensor data. Batch logs are timestamped, encrypted, and exportable for aerospace OEM supply-chain verification.

Engineering Questions Answered by Application Specialists
Comprehensive technical insights addressing real-world queries from mechanical engineers, quality managers, and global procurement directors.
What is the difference between shot peening and shot blasting for aluminium parts?
Shot blasting is primarily a material surface-preparation process engineered to strip oxides, foundry flash, and heat-treat scale while imparting an anchor tooth profile for coatings or adhesives. Shot peening is an audited cold-working process operating under strict velocity, media sphericity, and impingement angles to generate a deep layer of compressive residual stress. This compressive layer acts as a mechanical barrier against micro-crack propagation, mitigating stress corrosion cracking (SCC) and dramatically extending fatigue life under cyclical dynamic loads.
Which specifications can KOSHIN aluminium shot blasting and peening machines be configured for?
KOSHIN systems are purpose-engineered to meet stringent aerospace and automotive standards, including AMS 2430, AMS 2432 (computer-monitored shot peening), Boeing BAC 5730, SAE J442, SAE J443, and Nadcap AC7117 audit criteria. For explosion mitigation and dust management, all machines handling combustible light alloy residues adhere strictly to NFPA 484 and European ATEX directives.
Can KOSHIN execute pilot trial runs on our specific aluminium parts prior to machinery purchase?
Yes. KOSHIN maintains advanced R&D application laboratories in Singapore and our smart manufacturing facility in China. We perform comprehensive pilot test runs on client workpieces, generating empirical Almen saturation curves, residual stress depth measurements (via X-ray diffraction), optical coverage assessments, and roughness evaluations before finalizing your machine layout and locking the mechanical design.
How do KOSHIN machines prevent galvanic corrosion and ferrous contamination on aluminium surfaces?
Ferrous particles embedded in aluminium surfaces trigger aggressive galvanic corrosion cells. KOSHIN custom aluminium shot blasting machines integrate dedicated non-ferrous media loops—utilizing cast aluminium shot, spherical ceramic beads, or fine glass beads. Cabinet interiors are protected with virgin polyurethane linings, non-magnetic stainless steel liners, or ultra-high-molecular-weight polyethylene (UHMW-PE), preventing any contact with carbon steel.
What lifecycle support, maintenance, and overseas commissioning services are provided?
KOSHIN provides turnkey on-site deployment in over 50 countries, led by bilingual field service engineers. Commissioning includes Site Acceptance Testing (SAT), laser-aligned mechanical setup, robotic recipe programming, operator training, and annual calibration services. Spare wear components are cataloged digitally with global air-express dispatch from regional hubs.
