CE Certification Industrial Water Blasting Equipment Manufacturer & Product

Industrial water blasting machinery must satisfy the core Machinery Directive 2006/42/EC, the Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility (EMC) Directive 2014/30/EU. For high-pressure operations, compliance with harmonized European standard EN 1829-1 (High-pressure water jet machines - Safety requirements) is mandatory. This governs high-pressure hose burst resistance factors (typically a minimum safety factor of 2.5:1), unloader valve actuation response times, operator protective interlocks, and sound level mitigation.

Dry sand or grit blasting relies on solid abrasive particles driven by compressed air to shear surfaces, leaving residual grit embedded in micro-fissures and generating dangerous respirable dust (silicosis hazard). UHP water blasting (operating from 25,000 to 40,000 PSI) uses purely hydrodynamic kinetic shear force to strip coatings, thermal deposits, and corrosion down to bare metal (ISO 8501-4 Wa 2.5 standard) without substrate erosion, thermal stress introduction, or hazardous waste disposal costs.

Yes. Our automated systems are purpose-designed to pass Nadcap AC7117 audits. Integrated PLC controls continually monitor, alarm, and record vital operational parameters including liquid/slurry flow rate, air atomization pressure, nozzle traverse speed, Almen strip exposure duration, and turntable RPM. If any variable crosses the pre-locked tolerance limit, the process automatically triggers an interlock and stops the cycle, generating an unalterable, time-stamped digital batch report.

High-pressure pumps require clean, demineralized, or potable water with Total Dissolved Solids (TDS) under 200 ppm and filtration down to 10 microns (with a secondary 1-micron polish before the pump head). Excessive chlorides or silicates can trigger cavitation corrosion and micro-abrasion of carbide valve seats and sapphire/diamond orifice nozzles. KOSHIN provides optional onboard reverse osmosis and multi-stage bag/cartridge filtration skids to ensure water feed compliance.

Prior to shipping from our production facility, we conduct a full FAT where the buyer's actual component geometry is processed under production conditions. Real-time telemetry, Almen intensity curves, surface roughness profilometry (Ra/Rz), and 24-hour continuous pressure holding logs are compiled and verified. Upon arrival at the client facility, our Singapore-coordinated engineering field team executes the SAT, verifying electrical bonding, calibration, axis accuracy, and providing hands-on operator certification.
