Rework flat dies, special dies and coextrusion feedblocks

A complete rework is often the cost-efficient alternative to replacing a component or machine, whether it is a matter of scratched dies, damaged edges, wear, or mechanical and electrical components that are in need of repair. We make your components fit for production again – and, by the way, this is independent of the original manufacturer. There are no limits to the possibilities.


State-of-the-art service equipment 

We analyze the need for repair and recommend a rework tailored to your needs that will bring you up to the latest technical standards economically.

First, we record the existing melt flow channel geometry by 3D scan. Using this as a basis, we then recalculate and optimize the polymer flow using a rheological simulation software. Worn dies are then ready to face new demands, for example in an application with different raw materials and/or throughputs.

We leave nothing to chance: Final inspection, based on hightech processes and detailed human inspection.

The rework process

In our service center, our experienced rework specialists revamp your extrusion tools to their original condition - regardless of the manufacturer, from flat dies to special dies to coextrusion feedblocks.

Dismantling and returning the component

1

After consulting with us, send us the component that requires a rebuild.

Inspection and analysis of the repair requirements

2

We make a detailed inspection of your component. We determine the repair requirements and log the results.

Mechanical and electrical report

3

We discuss the repair requirements for the component with you.

Cost estimate and recommendation

4

We have the right solution for every requirement. Therefore, we only recommend the rework that is practical and sustainable for you.

Executing the rework

5

We clean, overhaul, rework, coat, grind, polish, repair, and replace spare parts – whatever is necessary to restore the component to its proper function.

Final inspection of the rework

6

The final inspection of the reworked component is based on the same strict criteria as the final inspection of our new components.

Returning the component

7

We send back the reworked component to you. If required, we provide support for refitting.
