Reverse Engineering and Reproducing a Knuckle Press Ram

Knuckle Press Ram Reengineered by Marando

A local customer operates several knuckle presses in a high volume packaging-material production facility. The presses are critical to the customer’s operation. After several in-house attempts to repair a cracked ram, the customer contracted Marando to reverse engineer for fit and to completely re-engineer for fatigue resistance and durability. The required eliminating the stresses that caused the original ram to fail. The first image below is the original ram (after multiple repair attempts) and the second is the re-engineered ram designed and fabricated by Marando.  The re-engineered ram has endured more than 1M press cycles without failure and allowed the customer to improve productivity and throughput by eliminating downtime and stabilizing the production process.
