One of the important process parameters to establish and record for any injection molded part is its injection or fill time. Research research reveals the limitations of popularly taught methods of establishing this critical parameter.

Purging High-Performance Engineering Resins
One of the fastest growing markets for commercial purging compounds is purging high-performance engineering resins. It is also one of the most difficult challenges, since both mechanical and chemical purging compounds have limitations when it comes to heat stability, residence time, flow restrictions, etc.

Not Your Father’s Purging Agent
There are two important messages for today’s processors with regard to purging. First, as we near the peak of the “rapid improvement” stage of purging technology, the products now available are not the same old purging compounds of the past. Second, the “low-hanging fruit” has been picked—future technical improvements will likely be incremental and future improvements in productivity will require a shift in focus, toward transition planning and process optimization.
