Know How

Melt Flow Rate Testing–Part 1
Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.

Pay Attention to Heat Transfer
Money will be lost if cooling is not done right.

Your Pre-Installation Checklist-Part 1
The work really begins after you've ordered your new machine.
