Real Factory Experience
One customer reported unstable bending angles during batch production. After a complete inspection, the root cause was identified as contaminated hydraulic oil combined with worn tooling.
The hydraulic oil was replaced, the tooling was renewed, and the machine was recalibrated. As a result, bending consistency improved significantly and production efficiency increased.
