PLC door locking and ejection versus a manually latched door — labour, safety, and when each is justified.
Semi-automatic
The hydraulic press cycle runs with operator involvement at the door or latch. Suitable when volume is moderate and an operator is already at the machine. Several NSG horizontal models are built this way with a manually latched door.
Automatic / PLC
Door locking, pressing, and ejection are sequenced by the control panel. Used with hopper or conveyor feed and multi-shift operation. Automatic vertical and fully automatic horizontal machines in our range are built for that duty.
Safety is not optional on either
Guarding, interlocks, and emergency stops are specified on both. Automation reduces how often an operator reaches into the cycle; it does not remove the need for training and lockout procedures.

It removes latch time and can run from a hopper. Throughput still depends on how fast material arrives. Semi-automatic is not ‘slow’ if the bottleneck is the feed, not the door.
