| Hand Held Cure Sensing DeviceAn ARM funded study by Remcon Plastics, Inc. and Penn-State University examined the use of ultrasonic measurements for cure detection in molded parts. The report has not been made public yet but the results showed that there is a correlation between the readings taken and the impact performance of the parts. The possibility is that a hand-held device could be made for QC evaluation of parts on the shopfloor without cutting them up or impacting them. Recent discussions with a maker of ultrasonic thickness gauges in the US have shown that they may be interested in investigating converting a standard hand-held ultrasonic thickness tester to show a 'cure-level' number. However, they are familiar with the rotomolding industry and have expressed concern about the level of interest from the marketplace. In order to help convince them that such development work would be worth pursuing, I am looking for feedback from the industry on whether such a device would be of interest to molders. In essence, it would perform in a very similar manner to a thickness gauge - calibration against a known standard (of cure) and instant readout of a 'cure-level' number. If you think this would be useful and would be interested in buying a reasonably priced version if they were available, send either me or the staff at ARM a fax, email or letter with your comments so that we can give the device manufacturers some feedback. Thanks for your help! |
