In rotary die-cutting, we offer further tool options in addition to our quality standard tools. In packaging production, a difference is made between the manufacturing process of flat die-cutting and rotary die-cutting. Die-cutting of corrugated board is often performed rotatively.
Ralf Nuyken, industry manager for corrugated board: "The objectives in rotary die-cutting of corrugated board is waste-free blanks achieved at maximum machine speed. Reaching these two goals is not always easy, because in rotary die-cutting, the cutting-die not only has to perform the function of cutting and creasing, but also the function of waste stripping. This is a difficult challenge for the cutting-die to master. The machine plays a central role in achieving this goal. But what is the point in having the best machine without a perfectly functioning cutting-die? That's why – in addition to our standard rotary dies – we have other die technologies that enable our customers to master any challenge they may face."
marbaspeed|r is a special high-performance tool equipped with the most advanced materials and manufactured using the very best manufacturing technologies: best rules, best dieboard materials, high-performance rubber as well as many other features. The tool equipment is tailored to your individual requirements. This means that not only cutting and creasing, but also stripping during rotary die-cutting of corrugated board is optimally achieved. marbaspeed|r is available for all corrugated board types and is suitable for both inline and offline machines. With a marbaspeed|r tool, the choice of rubber plays a significant role. Here, we use special high-performance rubber. Depending on your requirements, for example, the flexpower rubber, which is exclusively available from Marbach, is used. Its special structure makes this rubber extremely resistant to compression and gives it very high rebound elasticity. All of which ensures outstanding die-cutting quality of blanks. In addition, flexpower's high rebound elasticity means that waste is ejected quickly and efficiently during rotary die-cutting. The Marbach rubber is also tear-resistant and has low abrasiveness. This makes it highly resistant and durable. Even when other rubbers wear out and need replacing, flexpower still continues to work. Due to its composition, it can also be used without any hesitation for die-cutting of food packaging.
In rotary die-cutting, the trend is toward the use of rotary machines with active stripping technology. Such machines employ a different technique than conventional rotary machines. They have an integrated self-stripping system where the waste is stripped by means of mechanical ejectors. We have developed special tools for this purpose, which ensure high productivity with machines like these. Ralf Nuyken continues: "Our special tools are specifically designed for machines with active stripping technology. This is because the tool requirements are extremely high: For maximum performance, the special rotary tools must not only be extremely precise, but also have special equipment. The result is waste-free blanks in additon to very high running speeds of the rotary machine and in this way maximum productivity in rotary die-cutting is achieved." Special Marbach tools are suitable for all rotary machines with active stripping technology.
With Marbach rotary tools there is the right solution for every requirement.
Our division Marbach Die Supplies not only supplies materials and equipment for packaging manufacturers, but also entire in-house dieshop concepts including the required equipment.
We are well-known for our extensive portfolio. Thus, we also supply the global plastics industry with cutting-dies. The high-precision Marbach steel rule dies are designed for use directly after the thermoforming process. Here they ensure the reliable separation of plastic cups and lids.
Marbach Die Supplies not only supplies materials, but also machines for cutting-die production. One machine that stands for the highest efficiency in diemaking is the mjet|1. This compact waterjet machine cuts the ejector rubber for a cutting-die automatically and with absolute precision.
With our blanking tool alublanker, we feature a tool in our portfolio that has managed to convince numerous customers. This is because the alublanker is not only characterized by its low weight, but also by its high productivity.
The alublanker is a high-precision blanking tool lower part, made completely from one piece and in one milling operation. The separating grid is made of aluminum and is completely CNC milled.
