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.”
Since July 2017, the inventory of Marbach has included an on-site die-cutting machine from Brausse. After having used the past few months to provide employee training courses, initial customer training classes and to conduct product tests, the Marbach Academy will soon be officially opened. If you are interested in a training course, you can request a training brochure at firstname.lastname@example.org. Alternatively, all information about the Marbach training courses can also be found on the company's homepage www.marbach.com/trainings.
Marbach Werkzeugbau (Tool Manufacturing) will be represented at this year's SPE European Thermoforming Conference. The conference, to be held in Rome between 14-16 March 2018 is one of the most important events in the field of thermoforming. This is where Europe's leading representatives of thermoforming technology network. The participants are processors, end consumers, material suppliers, tool manufacturers, machine and equipment suppliers.
Marbach is known for its innovative strength. And for delivering maximum performance to its customers. Numerous customers of the cutting-die manufacturer have now confirmed that this is not just an advertising statement. Marbach is more than pleased with the positive response and will undoubtedly present further news from its innovation department in 2018.
For several months now Marbach has been equipping its premium tools marbaspeed, for flat die-cutting, and marbaspeed|r, for rotary die-cutting, with its new special rubber flexpower. This new type of rubbering stands for durability and best die-cutting performance. Statistics show the extent of its success: Marbach sold more than 2,000 rotary dies for corrugated board alone in the marbaspeed|r version.
