Marbach has implemented a new production process for the manufacture of rim-rolling screws for drinking cups. In the conventional process, rim-rolling screws were turned which limited flexibility concerning the contour. This flexibility however can be increased significantly through the milling process Marbach uses. With it, Marbach fulfils its motto “the right solution for every requirement” once more.
Thomas Reinhardt, Head of Sales at Marbach: “During the thermoforming process of cups, a sharp edge often occurs at the edge trim. This edge is unwanted for drinking cups as it is located where the lips touch the cup. In order to exclude the risk of injuries, these edges are rounded in a subsequent process, the so called rim-rolling.”
The rim contour varies from cup to cup, from brand to brand. That’s why a custom fitting rim-rolling screw trio has to be produced for almost every drinking cup. So far, Marbach hasn't had this product in its portfolio so the customers have had to procure the rim-rolling screws separately from other suppliers. This has led to mistakes, because the ordered rim-rolling screws haven't always fitted optimally to the thermoformed cups.
Conventionally, rim-rolling screws are produced through the production process of turning. Steps and edges can occur during this forming process. These often result in increased dust formation as well as unclean or scratched edges.
Marbach however mills the rim-rolling screws completely in 3D on a special processing machine. Stepless, in highest precision and surface quality. Every conceivable free formed contour can be replicated. Thanks to this production process, starting and final contours can be freely chosen. Also special contours are possible. Marbach rim-rolling screws can be produced with steel or aluminum.
Because Marbach offers both the thermoforming tool as well as the rim-rolling screws from a one provider, customers can be sure that these two parts are perfectly compatible with each other. And that they achieve a perfect result at the end of the process. The flexibility of the contour increases through the milling process and the customers get the right solution according to their requirements.
Thomas Reinhardt: “The first rim-rolling screws have already been implemented at our customers. The feedback is very positive. We will quickly accelerate the development of this market, because we see an enormous advantage for our customers.”
Marbach is already involved in its planning for the most important international trade fair for the printing industry: drupa 2020. And now there is only 1 year left until drupa opens its doors again. The last drupa was very special for Marbach: with the number of visitors reaching record levels. No previous drupa had more visitors at the Marbach stand than in 2016.
Marbach has continuously expanded its services in the past year. The newest member of the Marbach service family is the Marbach Performance Boost package. By which, Marbach supports its consulting service which makes its own process know-how available to its customers and thereby significantly increasing their productivity during the die-cutting process.
Marbach has been using for some time now a new rubber for rubbering cutting-dies. The name of this high-performance material is flexpower. Certified by ISEGA for use in the food industry, this rubber offers numerous advantages to operators. Marbach uses flexpower in corrugated board tools (both flat and rotary) and also sells it as raw material.
Marbach is one of the large material suppliers in Germany. Under the name Marbach Die Supplies, Marbach offers materials for packaging manufacturers that meet the requirements in the field of die-cutting. In order to support its customers even more in increasing their performance, Marbach has expanded its material portfolio.
