CE Certification Aluminum Oxide Grit Blasting Exporter & Service

Every exported KOSHIN blasting machine comes with a formal EU Declaration of Conformity (DoC), an exhaustive Technical Construction File (TCF), a localized bilingual Operator & Maintenance Manual per EN ISO 12100, complete electrical schematics complying with EN 60204-1, and risk analysis documentation demonstrating adherence to the Machinery Directive 2006/42/EC and Pressure Equipment Directive (PED 2014/68/EU) for pressure blast vessels.

While both use accelerated media, aluminum oxide blasting utilizes angular, sharp grit designed to etch, descale, cut, and create controlled micro-anchoring profiles for coating adhesion. Shot peening uses spherical media (cast steel, ceramic, or glass beads) to induce beneficial compressive residual stresses without removing parent metal, preventing fatigue micro-cracking and stress corrosion cracking (SCC).

To satisfy aerospace specifications such as AMS 2430 and BAC 5730, our blasting chambers are lined with heavy-gauge natural rubber or polyurethane curtains, internal structural parts are constructed from stainless steel (AISI 304/316) or polyurethane-coated steel, and non-magnetic stainless piping is employed throughout the media conveying system to guarantee zero iron transfer.

To ensure rapid and precise machine sizing, buyers should provide: part envelope geometry (CAD/drawings) and weight, material substrate composition, targeted surface roughness (Ra/Rz), required cycle throughput (parts per hour), media type/mesh specification (e.g., White Al2O3 Mesh 80), local electrical grid standards (voltage, Hz), and factory space constraints.

We perform comprehensive multi-day FAT runs at our manufacturing plant—testing mechanical reliability, safety trips, air leakage, dust collector emissions, and blast uniformity on customer test coupons. Upon arrival at the client facility, our Singapore and international service field engineers carry out SAT, on-site calibration, recipe locking, and operator certification training.
