There is no true ‘preform temperature’ because there is dynamic range of temperatures along the entire length of the preform.
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.
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.
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.
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.
