Vortex Tube Cooling Injection MoldIn more ways than one, custom injection molding is a hot industry.  It’s a competitive market, with a wide array of industries that demand injection molded components, each requiring a different approach to design, tooling, production and quality. There’s also the fact that molding plastic components requires the injection of molten materials at very high temperatures.

A large domestic component repair facility that specializes in re-building and testing hydraulic, electro-mechanical and fuel system components for the aerospace and aviation industries needed a solution to cool a fuel control valve for one of their customers. The control valve must accurately regulate fuel flow in response to the Vortex Tube cooling application for aerospace and aviation testingtemperature. One of the tests required the valve to be cooled to -25°F plus or minus 2°, and the fuel flow measured.

Cold Air Guns and vortex tubes are popular spot cooling products that are used in a wide variety of applications, ranging from cooling cutting tools such as band saw and circular saw blades, router bits, lathe tools, HSS drills and milling cutters used for machining of metals, plastics, paper and wood. They are also commonly used to cool parts, dehumidify gas samples, cool sensors, test thermostats and many other applications where an instant and reliable supply of clean cold air is required. Vortex tubes and Cold Air Guns have no moving parts and use only a clean dry source of compressed air for creating cooling capacities up to 6000 btuh (1758 watts).

Vortec recently received a call from one of our loyal customers inquiring about our vortex tubes. They were curious to see how long vortex tubes lasted before they should consider replacing them. Naturally, this peaked my interest, “Well hypothetically they should last forever if they are properly maintained. Why, how long have you had one?” Turns out, they have had one of our vortex tubes for over 45 years! Mind you, we were founded in 1961 (56 years ago) so this wasn’t the first vortex tube we ever built, but it’s not far off.
