Marbach offers various solutions to ensure safe embossing of packaging. The Marbach standard already contains suitable solutions for many applications. In addition, Marbach has developed a further option ensuring even more safety in embossing.
If packaging is not only die-cut, but also embossed, embossing clichés are then normally positioned on aluminum blocks. This means that the dieboard of the cutting-die contains cut-outs into which aluminum bases for the embossing clichés are inserted. This has the advantage that the embossing clichés have a very even base during the production process.
The aluminum substructure can be divided using a so-called Memopin, so that the embossing clichés can be set up quickly and easily from the front of the cutting-die. The tool can remain in the machine for make-ready. Also for die-cutting machines with closed machine frame. A make-ready from the back of the cutting-die is therefore not necessary.
Marbach development manager Klaus Rommel: "To ensure that the aluminum blocks are placed securely in the cutting-die and to avoid interruptions in production, Marbach provides two different ways of securing the aluminum blocks. With our standard method, the aluminum blocks are secured in the tool with two grooved pins. This prevents the aluminum blocks with the applied embossing clichés from falling out to the front. This type of protection is adequate in many applications."
However, in practice there are cases with particularly high demands or special requirements in which securing to the front is not enough for the operators. Then it is necessary to secure the aluminum block to an even greater extent.
Rommel continues: "For this reason, we looked for a solution that would ensure complete protection of the aluminum block against falling out either to the front or back. Our development has resulted in a completely new design of the aluminum block safety. With this version, the grooved pin is no longer required. Instead, a cut-out is milled into the aluminum blocks. The dieboard is given a "nose" at the appropriate point to attach the aluminum block to the dieboard and thus to prevent it from falling out on either sides".
This special version of the aluminum block safety device is designed for demanding requirements and offers the operator maximum safety. It can be used in the paperboard sector with multiplex, marbaplex and duramar tools.
Marbach has been a specialist for the production of cutting-dies for the packaging industry for many decades. In addition, the Marbach portfolio also includes tools for special technical solutions. One of which is the production of cutting-dies with particularly high cutting rules.
In May of this year, Marbach launched its new lower pin unit with high precision lower pins. This is mainly used for jobs where very small amounts of waste have to be stripped and where requirements for die-cut blanks to be waste-free are very high. With the lower pin unit, waste is stripped very safely in these areas of application. In the last months, several customers have already been using the new Marbach technology. Customer feedback has been consistently positive.
Marbach is working at full speed on various digitalization and Industry 4.0 projects.
