You’ll probably be passing out and/or eating a lot of candy today. 
Exergen IRt/c’s and SnakeEye thermal switches are inside equipment used to process and package candy.  The wax lip manufacturer American Candy, Hersheys, Sees, and Y&S Candies are all Exergen customers. Technical notes on Heat Sealing Temperature Control for Packaging Machinery and Detecting Hot Melt Adhesive are used by design engineers to help their companies increase production speed, and product yield.  Enjoy your treats with no tricks tonight! Happy Halloween!
