At the Deburring Centre in Poole it takes just 20 milliseconds to oxidize and remove the burrs with a thermal blast. The  whole process takes a little longer as the platen needs to rotate under the chamber, a piston raises it sealing the chamber, then a mixture of natural gas and oxygen under pressure is injected, and finally ignited. Exhaust gases are then released and the platen cycles round to be unloaded.

“It was a delight to discover a quick, efficient process that saved us the time consuming job of brushing every individual tooth,” said Michael Jackson. “The quality and consistency has been substantially improved. And despite the extra logistics of sub-contract, it has actually saved costs and given us a better product.”
