Technical Specification

Cryoblast’s blast media is suitable for all types of cryogenic deflashing equipment.

If you are deflashing rubber, nitrile, silicone, plastic or aluminium die cast mouldings then we can offer a blast media to suit.

Media comes clear as standard but absolutely any colour is possible – please enquire for details.

We manufacture our cubes and cylinders to a tighter tolerance than others...

We manufacture all our products to +/- 0.1mm.

technical specification Cryoblast UK

Although we are a fairly new company, we come into the market with many years of experience in polymer processing and extrusion and as a result we can offer media with enhanced properties, when compared to our competitors’ similar products.

Our state of the art manufacturing facility in Wales is home to custom built, highly developed processing machinery that has been honed and tuned to ensure that the polycarbonate shot blast media we manufacture is not degraded during the extrusion process and is also cut very precisely, to ensure that the customer receives the best product giving them the longest possible lifespan from their blast media.

We only use prime polycarbonate from major manufacturers so that our product remains consistent and of the best quality available. We have carried out extensive research and development into the polymer structure before, during and after processing, whilst monitoring and testing how it combines with specific additives to give certain synergistic effects. The net result is that the physical properties are tuned so that the polymer chains are broken down as slowly as possible during the cryogenic blasting process, to ensure maximum product lifespan.

Our quality systems enables our products to leave our UK manufacturing facility within our strict specification guidelines. This includes material purity, clarity, dimensional tolerance and squareness of cut.

All our product leaves the factory carefully packaged so to arrives with the customer in first class condition – exactly as it left the factory.
