die-cutting technology Thermoforming

Convincing performance when cutting plastic. SR tools from Marbach.

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.

The SR (Steel-Rule) tools used for this purpose are characterized by their high precision and special features. Michael Kiesel, Sales Manager at Marbach: "Our SR tools are based on a technology that is perfectly adapted to the requirements of cutting plastic. The blades are installed in a waterjet-cut free-flow holder and the individual elements are floated on the base plate. This means that the steel rule centers itself with the thermoforming part during the die-cutting process and the die-cutting edge is therefore the same for all cavities. But that's not all: with our Flexi-Tab-System, visible nicks are a thing of the past: this is because special nick-tabs make nicks disappear, thus producing a flawless cup. Last but not least, the Marbach cutting rule silverline ensures particularly good cutting quality and long tool life." 

Tools in SR design not only increase performance, but also stand for exceptional quality of thermoformed products.
