For some time now Marbach has been offering pure edge technology for achieving clean visible edges in corrugated board. Many customers are now using pure edge. It has been shown that this technology not only provides clean visible edges for corrugated board packaging, but is able to do much more.
Marbach developer Ingo Graham: "pure edge ensures clean visible edges for corrugated board packaging. We have known this for a long time. The success of pure edge and the feedback from our customers confirm this. Since we are enthusiastic about the technology ourselves, we have tested it on other applications. We have discovered that it is very versatile."
Knife protection in the edge area
The material to be cut often pushes the long straight edge knives away during the die-cutting process. The effect: due to the lateral material displacement, the cutting rule tip wears out relatively quickly at these points. This impacts the quality of the die-cutting result. The use of pure edge on both sides protects and stabilizes the cutting rules at the edges. The lifespan of the tool is thus extended and the cutting result significantly improved.
Stabilization of rule joints
In two-sided circumferential die-cutting, on narrow slots or on cutting contours, it is possible that the material which is being die-cut may squeeze the rules apart. This results in unwanted nicks. By using pure edge this can be prevented and the rule joints stabilized.
Increased service life
Pure edge can be used as a complete replacement of functional rubbering. Conventional functional rubber absorbs cutting pressure. In order to achieve good die-cutting results, this must be increased. But not with pure edge. Here the material is not unnecessarily tensioned and thus no additional cutting pressure is required. Pure edge should be used above all, in places where increased folding-spring-back forces in the material have to be avoided, but at the same time where no unnecessary traction forces should occur. As with 180-degree package folding, or nearby cut-crease rules for yoghurt crates with little surrounding material. But also on rules with transport nicks.
Solution for narrow areas
Depending on the requirements, pure edge is possible in widths ranging from 0.5 mm to 3.0 mm. This means that the technology can also be used in narrow places where there is simply no room for profile rubbering.
pure edge is made of steel. Compared to rubber, this is very wear-resistant and has an extremely long lifespan.
With pure edge, Marbach offers a technology that can be used in a variety of ways and which not only stands for attractive optical corrugated cardboard packaging, but also for long tool life.
In December 2017 Marbach introduced to the market its new cleaning device for corrugated board machines: the mplaten|cleaner. Since then, more than 10 of these devices have been sold. And further orders are in the pipeline.
The National Plastics Exhibition (NPE) takes place every 3 years in Orlando. The who’s who of the global plastics industry will meet in 2018 from 7 to 11 May. As a specialist for the production of thermoforming tools, Marbach will again be exhibiting there this year and presenting its latest developments.
Already in 2012, the Heilbronn-based die-maker Marbach had established a location in the USA with its subsidiary in Charlotte, North Carolina. This company has been constantly growing and has in the meantime established itself in the American market. For this reason, Jan Brunner, CEO Marbach America, was invited to the Heilbronn House of Commerce on the 8th March as an expert at the themed evening "Germany - USA: Relationship wise". This event, organized by the German Graduate School of Management & Law (GGS), the Kreissparkasse Heilbronn and the Chamber of Industry and Commerce Heilbronn-Franken, was about the economic and political situation in the USA and the relationship between the USA and Germany. But also about how this has changed - especially over the past year.
Marbach Werkzeugbau was represented at the 7th Thin Wall Packaging Conference in Chicago in 2018. This event took place on March 20 and 21. At this year's event, on the topic "Thermoforming 4.0" Marbach was able to convince visitors with a presentation on the current state of digital technology in thermoforming tools.
