CE Certification Small Sand Blasting Unit Factories & Manufacturer

A CE-marked small sand blasting unit undergoes documented design verification under the EU Machinery Directive (2006/42/EC), Low Voltage Directive (2014/35/EU), and EMC Directive (2014/30/EU). Crucially, pressure pots must comply with the Pressure Equipment Directive (2014/68/EU). Certified units feature interlocked safety switches that instantly stop blasting if the door opens, certified explosion relief venting for reactive dusts, and third-party laboratory verified sound suppression under 75 dBA.

Suction (venturi) feed uses compressed air passing across a gun nozzle to create a siphon that draws abrasive media from a hopper. It is cost-effective, suited for light deburring, light etching, and thin finishes. Direct pressure feed uses an ASME/PED-rated vessel to propel the media under direct air pressure, achieving velocities up to 4 times higher. Pressure systems blast heavy scale, create aggressive anchor profiles, and process hard alloys up to three times faster with significantly lower compressed air volume.

Yes. Our small robotic and semi-automatic precision cabinets are routinely equipped with closed-loop pressure regulators, digital media flow sensors (such as MagnaValves or sonic orifices), and rotary part-indexing tables. Operating parameters are recorded on PLC HMIs and can be transmitted via Ethernet/IP or Profinet directly to plant MES systems to meet AMS 2430, AMS 2432, and Nadcap audit standards.

KOSHIN systems are engineered with modular pneumatic recovery and cyclonic classifiers capable of circulating brown/white fused alumina, silicon carbide, glass microspheres, ceramic beads (Zirblast), stainless steel cut wire, plastic media, and walnut shells. Inner cabinets feature rubber curtain liners and boron carbide blast nozzles to prevent premature wear.
