Purging Tech Tip Tuesday with Robert Grzegorek SUBJECT:?The importance of Cushion ISSUE:?Cushion Variation. Maintaining a tight cushion is critical to your process. CAUSE: Variation in your cushion can result from several factors, including wear in the check ring assembly, barrel deterioration, process settings, and contamination or degradation accumulating within your system. SOLUTION: Identifying the cause of cushion variation requires some investigation. There are numerous helpful articles and troubleshooting tips available on this topic. One effective way to maintain your system and prevent buildup—particularly in the check ring/non-return valve—is through regular preventative maintenance purges. Recently, I conducted a trial using our purge product at a customer’s facility. The customer sought to improve changeover times for color and resin transitions and had never used a commercial purge before. By utilizing Dyna-Purge, we purged the injection unit, effectively removing not only residual resin and color but also carbon buildup. Upon restarting the machine, the customer was pleased with the significant improvements in both startup time and scrap reduction. Additionally, as an unexpected benefit, they noticed a tightening of their cushion variation—thanks to the thorough cleaning of the check ring assembly during the purge process.
