Case Studies

Issue

A plastic injection molding manufacturer in the USA was experiencing poor performance on an older, severely scored ram which continuously leaked, causing performance, safety and reliability issues. A competitive stacked v-ring set (i.e., cotton and rubber) only lasted between 3-6 months before excessive leakage required unplanned maintenance. The staff wanted to minimize leakage until they could reached a planned maintenance cycle and conduct a complete equipment overhaul to address the severely scored ram.
