OEM Paint Blasting Equipment Factory & Service

Industrial paint blasting focuses strictly on surface cleanliness (ISO 8501-1 Sa 2.5/Sa 3), removing oxide scale, rust, or existing coatings while imparting a surface anchor profile (roughness) to maximize mechanical adhesion. Controlled shot peening, by contrast, is a metallurgical fatigue enhancement process governed by aerospace standards (AMS 2430/2432). It fires spherical media at calibrated velocities to create overlapping dimples that induce deep compressive residual stresses, preventing fatigue crack initiation and stress corrosion cracking.

Our automated machines utilize closed-loop proportional pneumatic regulators coupled with MagnaValve® magnetic or precision electro-pneumatic metering valves. Real-time pressure sensors continuously measure air pressure directly at the nozzle inlet, adjusting valve throttling in milliseconds. If abrasive flow or pressure drifts beyond programmed thresholds (±5%), the system triggers an audible alarm, records the anomaly in the SCADA audit log, and safely halts cycling to protect the part from over- or under-blasting.

While tungsten carbide nozzles suffice for round steel shot or glass beads, aggressive abrasives such as brown/white fused alumina (corundum) degrade tungsten carbide within 20–40 hours of operation. For these setups, KOSHIN specifies hot-pressed Boron Carbide (B4C) or Silicon Nitride composite venturi nozzles. Boron carbide offers a service life of 500 to 1,000+ hours, maintaining exact orifice diameter, preserving the critical venturi pressure drop, and preventing costly compressed air consumption spikes.

Our dust collection systems feature PTFE-membrane, flame-retardant nanofiber cartridge filters operating with automated reverse pulse-jet cleaning. They achieve an efficiency of >99.9% down to 0.5 microns, ensuring exhaust particulate emissions remain strictly below 5 mg/m³ (and can be equipped with secondary HEPA H14 stages for <1 mg/m³), well within stringent OSHA, CE, and EPA indoor clean air regulations for recirculating air inside climate-controlled facilities.

Yes. We operate fully equipped testing laboratories featuring robotic blast cells, surface profilometers (measuring Ra, Rz, Rmax), and Almen verification gauges. Prospective clients can send sample components for trial runs where we determine optimal media selection, nozzle standoff distance, travel speed, and air pressure. All parameters are compiled into an empirical FAT report and transferred directly into the machine's PLC recipe upon project approval.

Standard automatic rotary or indexing blast cabinets are typically fabricated and tested within 6 to 8 weeks. Highly customized systems—such as multi-axis dual-robot cells or large-scale walk-in blast rooms with automated floor recovery systems—generally require 12 to 16 weeks from approved engineering drawings to factory acceptance run-off, representing an accelerated schedule compared to the industry standard of 24 to 32 weeks.
