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 launched its tool marbaclean onto the market last year. Product safety and conformity to highest hygiene demands are benefits, that are attracting great interest in the market. marbacelan is ISEGA certified and therefore suitable for packaging production in the food industry – particularly for direct packaging, which has direct contact with the packaged goods.
Marbach knows the requirements of the market. Especially for manufacturing cigarette packaging where the demands on quality are high, and the packaging process has to be especially productive. With the crease bend tester, Marbach offers its customers a device with which creasing forces and folding resistance of a package can be tested precisely. For the smooth packaging process of cigarettes.
Marbach presented some time ago its technology for optically appealing visible edges in corrugated board packaging. Since then various customers are employing pure edge. One of these customers is the Sealed Air Verpackungen GmbH in Alsfeld, Germany. Sealed Air has been so convinced by this technology that in the meantime all its tools for single-wall corrugated board have been equipped with pure edge.
After the installation of a die-cutting machine at Marbach at the beginning of July, the preparations for the new training center are running at full speed at the Heilbronn-based die-maker. The official start is planned for the beginning of 2018. Marbach will then offer its customers training on the topics of die-cutting of paperboard and corrugated board. The focus will be on topics such as productivity and the significant reduction of make-ready time.
