How to diagnose hydraulic pressure loss on a Bucher Emhart NIS / FlexIS IS machine
Hydraulic pressure loss on an IS machine slows the mechanisms and leads to timing errors. Check the hydraulic pump output and filter condition before tracing individual cylinder seals.
How to diagnose mold cooling failure on a Bucher Emhart NIS / FlexIS IS machine
Mold cooling failure causes heat check cracks in the containers. Check the cooling air flow to the affected section and inspect the mold cooling passages for blockage before replacing the molds.
How to diagnose plunger mechanism timing faults on a Bucher Emhart NIS / FlexIS IS machine
Uneven container walls usually trace to the plunger arriving at the wrong point in the cycle. Check the plunger timing against the section timing diagram and verify the plunger air cylinder operation.
