Abstract:
1. A method of measuring the placement of material forming a blow-molded plastic container after the container is released from a mold of a blow molder having a plurality of molds, wherein each plastic container comprises a continuous sidewall and a base, the method comprising the steps of: inputting to a microprocessor a temperature profile of a reference container as a standard reference temperature profile to define stored data, wherein the reference container has a material distribution that meets desired material placement requirements for that reference container; blow molding into a mold a plastic container defined as a second container; detecting heat emitted from the second container via infrared light with an infrared camera to form an infrared image of the second container after the second container is released from the mold; converting the detected infrared light image into corresponding electrical signals; transmitting the electrical signals to the microprocessor; comparing in the microprocessor the electrical signals with the stored data regarding desired material distribution; and producing output information regarding the placement of material forming the second container.
