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 […]
Purging Co-Extrusion Dies…
When using mechanical purging compounds to purge co-extrusion dies, it is important to not purge all the extruders through the die at once to prevent excessive die pressure buildup. Question: I have been told “For co-extrusion it is important to purge from first to last and not all at once”. Could you explain this? My […]
Fill Time Monitoring…
The fill time is not expected to vary much form shot to shot. Typically, large variations indicate a parameter change or a change in machine performance. Question: We are using fill time as one of the process outputs for monitoring the process consistency. There is hardly any change which is showing variations. My Question is it a […]
