Gravitrol® extrusion control offers the benefits of improved product quality, reduced material usage, quicker startups and product changeovers, reduced scrap, and improved product repeatability.
At the same time, it reduces the operator’s workload by maintaining a constant output, regardless of screen pack or material variations.
The system uses Process Control’s proven Gravitrol® software to automate the control of the line and hold the extruder output to +/- 0.5% by weight. This tight control of output means that product can be made consistently within tolerance at the lowest possible cost, thereby saving thousands of dollars in resin.
