Why Ultra Purge™ Purging Compounds?

Black specks and carbonised deposits pose high risks during injection moulding and extrusion processes. The consequences: scrap and machine downtime. A new video illustrates how Chem-Trend Ultra Purge™ purging compounds make cleaning simple, safe and economical.

For injection moulding machines and extruders, the shutdown and restart procedures present a particular problem. This also applies to material or colour changes. These processes can produce carbonised deposits and other residues that result in tiny inclusions (black specks) in the final product. The consequences are serious: due to these product defects, the quantity of rejects increases rapidly, the productivity decreases accordingly, and machines may have to be stopped. Also, the need for manual cleaning is very cost- and resource-intensive.

Full cleaning ensures stable production

Such consequences can only be prevented by completely cleaning the machine: it is important to remove deposits in good time so that black specks cannot form. To ensure this happens, innovative purging compounds are necessary. The use of Ultra Purge™ purging compounds from Chem-Trend is well-proven. Ultra Purge™ purging compounds can be used during the shutdown and start-up of machines and extruders. Cleaning of screws, cylinders and hot runners with Ultra Purge™ also removes carbonised deposits from the system, which can cause black specks even hours after production has resumed.

The whole process is illustrated in this recent video from Chem-Trend.
