A major tire manufacturer for the automobile industry, reached out to us with manufacturing troubles. They were having a tough time with white sidewall rubber grinding, which is the white, rubber ring that’s inserted into the tire mold. A thin, black layer of rubber forms over the surface of the ring when the molding is complete. To remove the thin, black layer they use a grinding wheel, but in normal operations the wheel becomes hot, loads up with melted rubber and produces a significant amount of smoke. They were currently using air jets, in an attempt to cool the rubber, but this process failed to cool the rubber fast enough and generated too much noise.

A great article by Eli Plaskett, from Modern Machine Shop, showing the versatility and effectiveness of our Vortex Tubes. There are some great tips on how to make the most out of your compressed air solution. 
This technology offers an alternative to traditional liquid coolants by providing a clean stream of air as cold as -30°F to cool cutters and workpieces during machining.

A manufacturing engineer, at a large diesel engine manufacturer, called me looking for a cooling solution. They needed to speed up cooling of a hot 3” diameter cam gear that is a shrink fit onto the engine’s crankshaft. They were using four cold air guns from a competitor of ours to cool the gear and they needed a solution that would allow them to increase the cooling capacity, quickly adjust the cold air temperature and reduce the cooling cycle time.
