Technology from HENKEL + ROTH
Unlike other machines, this single-setting machine is equipped with a rotary indexing table to make it easier to pick up workpieces.
A major advantage is that it makes work easier because the machine and the worker can work simultaneously without getting in each other's way. The worker can remove the finished parts and insert new components in a protected area while the machine sinks the bushings into the plastic parts.
Once the insertion machine has fully loaded the rotary indexing plate, the plate rotates 180 degrees. As the device continues processing the parts immediately, the time required to change a workpiece can be reduced by one second.
Simple countersinking thanks to new technologies
As the automatic sinking machine is equipped with servo axes, the sinking positions of the bushes can be programmed differently (3 degrees of freedom). During the countersinking process, the machine is able to regularly measure the depth of the bushes and control them individually. This protective mechanism can compensate for elastic deformations that occur during the countersinking process.
A process PLC, which is equipped with an adaptive position controller, ensures a controlled pressing process. In addition, the automatic sinking machine contains an intelligent servo spindle press, which reduces the reject rate many times over. The quick-change fixture can be exchanged in no time at all in just a few simple steps, which is why the automatic die-sinker is suitable for processing different plastic parts.
A vibratory spiral conveyor ensures that the bushes are provided quickly. The bushes are generally heated in a continuous oven. Another option for heating the bushes is electricity. This process is also known as inductive heating.
The advantages in a nutshell

- Machine & worker can work simultaneously
- Reduction of changeover times
- Freely programmable sinking positions of the bushes
- Measurement & control of the sinking position
- Process PLC with adaptive position controller
- The machine can be converted by replacing the quick-change holder
- Vibratory bowl feeder provides the bushings
- Heating of the bushings in a continuous furnace or by induction
