Learn how a manufacturer successfully reduces costs for a new valve insert by $175,000.

Avient maintains an R&D stage gate process for new developments and has an internal goal to reach 100% of these resource intensive projects to support sustainable and carbon footprint related projects. Additionally, in November 2020, Avient opened our new CycleWorks facility in Pogliano, Italy. The new lab and plant will conduct cutting edge chemistry testing and evaluations to help customers tackle and overcome the challenge of plastics recycling and the goal of a circular economy.

Open-loop recycling streams typically consist of raw materials that are recycled and manufactured to make a variety of new products – splitting the allocated carbon emissions amongst the raw material supplier and the polymer manufacturer. 

FOR CONVERTERS Compete in premium markets – Gravi-Tech material’s luxury aesthetics allow plastics converters to reach new markets by competing against aluminum, zinc, iron, or steel and other alloys. Use the optimum velocity from the previous step and once again, fill the part to 95% full • Add just enough hold pressure to fill out the part, until it is just full - There should be sinks in the part; it should not look like a final part • Increase the hold pressure until the part slightly flashes, around the parting line of the part • Once these two values have been found, take the average of them, and this is the hold pressure to be used when processing - If sinks are found in the part at the new hold pressure, increase it until the sinks disappear or flashing occurs. Very difficult to resolve through processing Root cause: Nominal wall thickness is not maintained or uneven cooling. 42 Gravi-Tech Uneven cooling Damaged ejection Leaking check ring New lot Melt temperature Injection speed too high Cooling time too low Hold pressure too high Hold time too low Transfer too high Plate with lower friction coating Maintain constant wall thickness Maintain constant cooling Reduce sharp corners Gate from thick to thin Increase/decrease cooling time Reduce mold Reduce melt Warpage • Parts will warp to the hotter half of the mold Root cause: Internal stresses caused by uneven shrinkage.

Our hallmark programs of NextGen and PolyMasters continue to develop tomorrow’s leaders today, and in 2019 we launched a new program called ENGAGE, which connects our front-line manufacturing associates to our culture, customers and co-workers to drive future engagement and performance.

Often times, this “new normal” of disinfection can lead to material failure through a phenomenon called environmental stress cracking (ESC).

Strategies to counteract failure in this “new normal” of heightened disinfection are two fold: One, selecting materials with improved chemical resistance and two, modifying part design to reduce residual stresses.
