Bucher Emhart NIS / FlexIS

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.

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.

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.
