Service spectrum

Reifenhäuser uses a highly experienced team and the newest CAD software during construction.
The superior quality of our products is a result of 3D construction techniques and a continuous manufacturing chain which allows the production of cost effective customised components with ideal flow geometric properties. Worth mentioning are

Melt distribution is almost independent of operating position
Optimised behaviour of raw materials and dye changes
A short uniform dwell time in all die-head ranges
Reduced discharges, longer periods of operation
Ideally suited for coextrusion operation

Calculation and design
Software to design and simulate can be purchased, but achieving the best possible results requires more than that.
A team of experienced colleagues, use of cutting edge software for design and simulation and extensive tests in the in house laboratory guarantee an extrusion die head that is optimised for its specific application.

Highly specialised employees can manufacture extrusion die-heads for various applications with widths of up to 6 m using state of the art milling centres with 4 or 5 axles.
Continuous investment in the training of our employees, machines, and hard- and software ensures our expertise and capabilities for the future. Along with a process-oriented organisation, a continuous CAD/CAM chain guarantees short production processes, flat hierarchies, low throughput times and cost effective manufacturing.

Service on site
In addition to assembly, dismantling and cleaning, our expert team also carry out measurements and inspections as well as repairs on site.
The on site service also includes training for system operators and maintenance personnel.

The Reifenhäuser Rework program involves renewing extrusion die-heads after they have been in operation for a long time; die-heads can also be modified and upgraded as an alternative to buying new ones.
This also allows extrusion die-heads to be adapted to new product requirements.

New Contact Roll for Cast Film Winders

New Contact Roll for Cast Film Winders Eliminates the Need for Rewinding.

Troisdorf, 02.07.2013. Reifenhäuser Cast Sheet Coating has launched a new contact roll with special micro structure for MIDEX rotary arm winders. The roll helps reduce production costs, enhance the winding quality and increase production safety.

The new roll saves producers a complete production step: Thanks to its innovative surface, a precise build-up of edges is ensured so that rewinding of the film can be dispensed with in many cases. This has a positive effect on the production costs and saves time.

A special micro structure and soft rubber-coating improves the contact to the web and prevents undesirable film warts which avoids blocking of the film layers in the winding process. In the past, particularly thin PP film of less than 30µ was affected. Producers usually counteracted this phenomenon by using expensive additives. Now, these can reduced to a significant extent.

The new roll also eliminates the need for electrostatic charging of the film used in the past to improve the winding quality, even though it was detrimental to the working conditions of the operating staff due to possible electrostatic discharges. These are not only unpleasant to people, but may become a safety risk, depending on the environment, for instance in production halls where colours are worked with at the same time. In addition to facilitating film conversion processes, the new roll reduces this risk to a minimum.

Höxter-based Wentus has tested the new roll and is very satisfied with the result. “Our winding quality could be significantly improved. This is very important both for us and our customers. Thanks to the new contact roll, we are able to produce film with excellent quality at high winding speeds,” says the extrusion manager of the film producer.

The roll is available as of now and can be retrofitted to all MIDEX rotary arm winders.

MIREX MT technology transfers

MIREX MT technology transfers
precision and automation level of up-to-date machine tools to polishing stacks.

Troisdorf, 02.07.2013. Inspired by the precision and high level of automation of modern CNC machine tools, Reifenhäuser Cast Sheet Coating has developed MIREX MT, a new polishing stack technology that outperforms by far all state-of-the-art polishing stacks with regard to reproducibility and sustainability. The new patent pending polishing stack technology is the first and only system in the market that combines modern digital technique with sophisticated mechanical engineering.

The MIREX MT product range allows film producers to adjust the polishing nip more precisely by a factor of 10. In contrast to other polishing stacks, nip adjustment of MIREX MT can be effected fully automatically, even during running production. In the past, the line had to be stopped for manual adjustment of the correct nip on a trial and error basis. MIREX MT works at the push of a button and the set data are 100% reproducible.

The high level of automation has a positive effect both on the film quality and production cost. Due to the uniform thickness profile over large web widths, producers are able to obtain film of considerably improved precision while saving raw material. Thanks to the automatic adjustment, set-up times are only a quarter of the time needed in the past. The amount of waste can be reduced by 75%, depending on the production conditions.

When it comes to sustainability, the new MIREX MT technology outperforms all other polishing stacks available in the market. Hydraulic systems are completely dispensed with so that the polishing stack developed by Reifenhäuser Cast Sheet Coating is suited for clean room production. Film producers can benefit from triple savings in energy: no need for hydraulic pumps in permanent operation, improved efficiency of roll drives, no energy-intensive adjustment of the nip.

As Helmut Meyer, responsible developing engineer, puts it: “Forget what you know about polishing stacks. With MIREX MT we have completely changed the current state-of-the-art technology and chosen a different approach. Our courage paid off: In the past, it was hardly conceivable what the new polishing stacks are able to accomplish with regard to precision, automation, and reduction of production cost.”

MIREX MT combines the roll set-on system and the nip adjustment system forming a mechatronic drive unit. The angular position of the first polishing roll can be varied by 30 degrees using a X-Y adjusting device. Individual drives arranged on both sides of the roll facilitate axle crossing of the first two rolls – a prerequisite for a uniform film thickness profile. Reifenhäuser Cast Sheet Coating has optimized the existing roll drives by combining several low-backlash planetary gearboxes with servomotors and torsion-resistant couplings.

MIREX is available in three designs, depending on application, film thickness and production capacity: Smart, Standard and High Quality.

Smart: Less challenging applications (PS/PP) and low to medium output of maximum 1.200 kgs per hour
Standard: Medium to higher capacities selectable in three steps from 1,000 to 3,000 kgs per hour.
High Quality: Ensures high performance for specific applications in terms of output, speed and different film thicknesses and film properties.

Reifenhäuser Cast Sheet Coating will be presenting the new MIREX MT polishing stack for the first time on booth C22 at the K show to be held in Düsseldorf from October 16 to 22, 2013.


The polishing nip of MIREX MT is set during production at the push of a button. The setting accuracy is improved by a factor of 10 compared to polishing stacks used in the past.

With the patent pending MIREX MT technology, Reifenhäuser Cast Sheet Coating transfers the precision and level of automation of up-to-date machine tools to its polishing stacks.
