Plastic media blasting
Plastic media blasting (PMB) is ideal for a wide range of uses including paint stripping, surface preparation, mold cleaning deflashing and deburring. Plastic media abrasives are used for treatment of soft or delicate substrates ie, aluminium, fiberglass and composites, and can remove coatings layer by layer without causing damage or etching to the underlying surface.
Plastic media blasting is commonly carried out on aerospace components which are inherently of high value. For this reason the blasting process must be tightly controlled to avoid blasting damage to valuable parts.
An environmentally friendly safe alternative
PMB is an environmentally friendly safe alternative to wet chemical stripping and significantly reduces the generation of hazardous waste. PMB has proven to be faster, less damaging to the substrate and much less expensive than wet chemicals.
Our PMB blast room is designed and built specifically to deal with the special requirements of using plastic media as the blasting abrasive.
Media recovery is accomplished with our P Series pneumatic conveying recovery floor to ensure no abrasive breakdown occurs during recovery.
High efficiency abrasive cleaning
Reusable media is separated from dust and paint chips in a 4 stage high efficiency reclaim separator. This fully adjustable unit ensures only correctly sized and fully cleaned media is returned to the blasting pot. Steep cone blasting pot ensures a constant, surge free, media flow to the abrasive metering valve.
Precise abrasive metering valve allows infinite abrasive flow adjustment and permits micro adjustment to obtain the perfect abrasive flow rate. The blasting pressure is controllable from inside the blastroom, enabling the blasting operator to monitor and adjust the blasting parameters from inside the blastroom without having to stop blasting.
