You’ve seen those promo displays where the edges of the plastic seem to light up. The company that makes them contacted me because he was having problems machining the edges to a smooth finish so that they would light up.

He uses a router bit to machine the edges. The router generates heat causing the plastic to soften and not machine well. EXAIR suggested their model 5215 Cold Gun to provide refrigerated air to cool the bit.

It worked so well that he was able to save $8 per sheet in what would have been scrap.

Do you have a cooling application that you would like to share with us? Speak with one of our Application Engineers by calling 1-800-903-9247.
