Purging for Scientific Molders

The four online training courses in Routsis’s Purging series will teach scientific injection molders about proper material purging concepts and procedures.

The first two courses cover common purging techniques and effective purging procedures – while the third course details common types of purging compounds, how they work, and the advantages and disadvantages of each type. In the final course, users are shown how to effectively compare different purging procedures and compounds – and guided through completion of the accompanying Purging Analysis Worksheet.

We've also developed a Purging Cost Analyzer “app” that runs on both PCs and Macs – as well as iOS and Android devices. This powerful, free tool complements the online training courses and allows users to quickly and easily compare various purging compounds and/or methods.
