On the Way to Production 4.0

The Crailsheim-based filling machine manufacturer groninger is taking the next steps towards expanded automated production. In order to be able to deliver the best possible production results in the future, investments were made in two fully automatic trovalizing and vibratory finishing machines.

groninger invests again in its production at the Crailsheim location. The family company spent over 50,000 euros on two fully automatic trovalizing and vibratory finishing machines. The lines are able to process production components up to the size of a shoe box, which are installed in groninger’s filling and closing machines.

The entire thing is quite simple. The lines are set in motion by vibration. The abrasive granulate contained therein processes the based on the requirement—deburring, edge rounding or polishing is possible.

“For larger components—especially metallic ones—the use of such lines is now often standard in the industry. However, we have succeeded in applying this technology to even the smallest plastic components. We tinkered until we found the perfect mixing ratio for our workpieces for granulate, operating time and speed of the lines” states Andre Früh, Production Group Manager, with satisfaction.

Admittedly, it is not an easy task, since some workpieces have a thickness of only a few millimeters. In the past, deburring such plastic parts by hand was a real challenge due to their fine texture.

“You’ll need a sure instinct for this task and it takes a lot of time” says Timo Hägele, Production Team Leader, and he adds “Now, the entire thing runs parallel to other tasks and is almost fully automated. This is a great relief for our employees. We gain flexibility and freedom for other tasks.”

For groninger, the acquisition of the lines is another important step towards expanded automated production. “We would like to continue to set standards in our production and meet the highest standards in the future. This is not only what our customers expect from us, but it is also what we expect for ourselves. This is the reason why all the parts built into our machines—no matter how small and filigree they may be—must meet these requirements” explains Früh and Hägele. The lines have been running for about 400 hours—since spring. And, so far, the results are impressive: “We are very satisfied” says Hägele.

In the course of the acquisition of the trovalizing and vibratory finishing machines, the workstations at the deburring department were also completely redesigned—new, height-adjustable workbenches and overall more space between the workstations.  “All in all, it’s all an unbelievable relief for us and working is so much more fun”, André Kronenwetter and Fikret Sentürk agree, who both work at the deburring department. It is an investment that turned out to be more than beneficial in two respects.
