The WITTMANN W8 and WX robot generations come with the patented SmartRemoval function as standard, which automatically shortens the time required for parts removal from the mold area without any operator intervention.

In addition to shortening of the unproductive time, the function can lower total energy consumption for the system through reduction of the heat loss caused by the open mold and ultimately contribute to more consistent process quality.

The injection molding process as such is basically left completely untouched, since SmartRemoval only influences the time required to remove the part from the machine. All parameters set on the processing machine remain unchanged.

WITTMANN’s R8 and R9 robot control systems automatically calculate how long the mold opening movement will take from the first cycle.

Then, in all subsequent parts removal processes, the system no longer waits for the complete opening of the moving mold half, but instead already starts to move the vertical axis of the WITTMANN robot beforehand.

Once the mold is fully opened, the axis is already moving at an optimal speed and can be accelerated still further for the actual removal process inside the open mold area.

In contrast to the conventional sequential removal process, the gripper of the robot arrives earlier at the position where the transfer of the molded part takes place.

The synchronization with the ejectors functions in a similar way. Based on previous automatic measurements, the WITTMANN robot already issues the ejector signal before it arrives at the parts removal position, so that it can take over the parts directly without having to wait for the ejectors’ response. This process is designated as “Move In”.

In the subsequent “Move Out” phase, the ideal timing to send the machine the “close mold” signal – before the WITTMANN robot has moved completely out of the mold area – is calculated in a similar way.

The aim of these measures is to eliminate from the process the delays caused by electrical signal transmission.

In an identical program sequence with, say, 1.0 s parts removal time, 0.2 s can be saved by using a small robot from the W818 series, that is, about 20%.

With larger models, such as the WITTMANN WX173 robot, a shortened parts removal time of 1.2 s instead of 1.7 s is reached in similar test arrangements, that is, a reduction of almost 30%.
