Measuring Preform Temperature…
There is no true ‘preform temperature’ because there is dynamic range of temperatures along the entire length of the preform. Question: What should the finish temp be on the preform as it leaves the oven? My Response: There is no specific temperature, but typically a profile this is specific to the material, mold, and equipment you are […]
Transferring with Temperature Sensors…
All the Scientific Molding principles apply when developing a process for V-P transfer using a temperature probe as with a process developed with position transfer. Question: How does the development of a process differ when using a position transfer vs.a transfer via temperature sensor? My Response: The purpose of transferring using a signal from a temperature sensor […]
Should Employees Train at Home?
Salaried employees are much more likely to train outside of the office since they can pick locations/times which are much more convenient for themselves. Question: How common is it to have employees take the online training at home? My Response: Salaried employees tend to be more motivated to train on their own time. If the […]
