Verified systems ready for Nadcap, AMS, and high-spec industrial surface finishing applications worldwide.
The Next Epoch in Plastic Media Blasting (PMB) Engineering
Plastic Media Blasting (PMB) was initially conceptualized as a non-chemical, eco-compliant solution to eliminate hazardous chemical paint strippers and reduce toxic VOC emissions across military and commercial aerospace overhaul facilities. Today, PMB represents a sophisticated, non-destructive surface finishing paradigm engineered for delicate substrates, lightweight composite structures, and critical micro-electronic housings.
By leveraging thermoset materials such as urea, melamine, and acrylic media characterized by controlled Mohs hardness (3.0 to 4.0), KOSHIN’s PMB machines achieve efficient de-coating, depainting, and deflashing without micro-pitting, dimensional erosion, or altering substrate metallurgical properties.
- Substrate preservation on thin-gauge 2024/7075 aluminum, magnesium alloys, and carbon composites.
- Zero chemical waste, meeting stringent EPA, OSHA, and European REACH de-painting mandates.
- Precision kinetic density balancing preventing substrate warpage and surface profile damage.
Global Industrial Procurement Demands in PMB Systems
Aerospace tier-1 manufacturers, defense contractors, and automotive e-mobility giants require specialized operational parameters when auditing plastic blasting equipment factories.
Aerodynamic Media Separation & Vibratory Sieving
Plastic media exhibits a delicate density ratio compared to steel grit. Premium machines integrate dual-stage cyclonic separators combined with multi-deck vibrating sieves to eradicate broken fines, airborne dust, and degraded particles, maintaining media efficacy and blast uniformity.
Particle Sizing ConsistencyLow-Pressure Precision Fluidization Control
Operating pressures for PMB must be controlled within stringent thresholds (15 to 45 PSI / 1.0 to 3.1 bar). KOSHIN’s pressure regulators utilize closed-loop differential transducers ensuring zero pressure surging, eliminating potential cladding removal on aerospace structures.
Tolerance ±0.5 PSIElectrostatic Grounding & NFPA Explosion Proofing
High-velocity movement of non-conductive plastic particulates generates critical triboelectric charges. Factory installations mandate comprehensive ATEX/NFPA-compliant conductive grounding, HEPA spark traps, and anti-static filtration systems to mitigate combustible dust ignition.

Frequently Asked Questions on PMB Technology
In-depth responses compiled by KOSHIN's lead application and surface-finishing engineers.
How does plastic media blasting differ from conventional sand or steel grit blasting?
Conventional abrasives like silica sand, aluminum oxide, or steel grit exhibit high Mohs hardness (7.0 to 9.0) and high kinetic impact mass designed to cut into the substrate, create anchor profiles (Ra), or induce compressive residual stress (shot peening). In contrast, Plastic Media Blasting relies on soft thermoset polymer granules (Mohs 3.0 to 4.0). PMB transfers sufficient kinetic energy to fracture and peel brittle coatings, adhesives, and resin burrs while deforming elastically upon contacting softer substrate metals (aluminum, magnesium, titanium) or carbon fiber matrices without etching, eroding, or inducing thermal distortion.
Which industry specifications govern KOSHIN's plastic media blasting equipment?
Our plastic media blasting machines and processes are engineered around critical aerospace and military technical directives, including MIL-P-85891A (Plastic Material Blasting Media), Boeing BAC 5725 (Stripping of Organic Coatings by PMB), Airbus ABP 4-1123, and FAA advisory circulars governing dry composite stripping. Furthermore, our machines are built to comply with industrial safety guidelines including NFPA 652 and NFPA 654 for combustible dust mitigation.
What media recycling efficiency can be achieved in continuous production?
Depending on working blast pressure (typically 20 to 35 PSI) and media classification (Type II Urea, Type III Melamine, or Type V Acrylic), KOSHIN PMB systems recover between 92% and 98.5% of reusable plastic media per cycle. Our cyclonic vacuum separation towers and vibrating screening decks ensure that only pulverized media dust and paint debris are directed to the HEPA dust collectors, allowing the same high-grade media to be reused 12 to 25 times.
Can KOSHIN run qualification trials on customer sample parts before equipment purchase?
Yes. KOSHIN operates dedicated process testing laboratories and pilot lines in Singapore and China. We provide full experiment services, including micro-finish topography inspection, optical coating removal verification, substrate dimensional loss testing, and process recipe qualification. Validated parameters are documented, locked, and directly embedded into the Siemens/Allen-Bradley PLC software of your custom-built machine.
How does KOSHIN address static electrical charges and explosive dust hazards?
Plastic media particulates moving at high velocity through blast lines naturally generate static charges. KOSHIN equips blast cabinets with conductive urethane liners, copper-grounded anti-static blast hoses, ionizer air-knives at loading/unloading doors, and ATEX/NFPA-compliant explosion venting and fire suppression mechanisms in all downstream dry dust filtration systems.
