temperatures can be verified within seconds without the need for preheating probes. (Again, this is not necessarily a replacement, but a quick gut check of what's going on. It's a great supplement.) Even operators running or verifying the machine parameters can be trained easily to use the equipment. If you have critical processes and want an easy way to troubleshoot, verify and maintain them, it cannot be overlooked how good this equipment has become. It also can't be overlooked that the speed of the results and ease of use makes it easy for anyone to solve problems quickly. Juno Pacific is a molder and not in the business of selling TICs, so this article is not intended as a sales pitch, but to simply make molders aware of the fact that there are faster, better ways of getting to root causes of problems. If you're thinking about TICs, take the time to validate and verify that they are going to work the way you want them to. Consider multiple brands and models. Test them and then decide what works best for your envi- ronment. It doesn't have to be too complicated to produce convincing results that spending the money will be worth it in the long run.
