100% recycled material – 100% quality: New 3-layer PVC pipe head from KraussMaffei Extrusion

-

Sustainability is not just skin deep – it often begins underground: in our cities' pipe systems. This also applies to the production of PVC sewage pipes. At K 2025 in Düsseldorf (October 8–15), KraussMaffei Extrusion will present a new 3-layer pipe head that allows the safe and stable processing of up to 100% recycled material.


The company is thus sending a clear signal for greater resource conservation in pipe manufacturing while also meeting the growing demands of the circular economy.

New patent-pending flow system

Reliable processing of up to 100% recycled material in all three layers

Significant savings in material costs

Sustainable response to the growing market for PVC sewage pipes


Two years of development for a new standard:

The KM-3L RK 42-HP is the result of a completely new development – not a further development of existing concepts, but a pipe head that has been redesigned and simulated from scratch. With a processing range of 400 to 1,200 kg/h and a diameter of 110 to 250 mm, it is ideally suited for large-scale industrial applications. "With the new KM-3L RK 42-HP, we are presenting the most advanced 3-layer pipe head for PVC applications. Our customers benefit from economical, sustainable, and outstanding quality pipe production," says Ralf Benack, CEO KraussMaffei Extrusion.

 

Intelligent design for maximum performance:

At the heart of the new die head is a high-precision, patent-pending flow system with symmetrical material feed for all three layers. The solution for the core layer is particularly innovative. It benefits from a highly efficient 1-to-8 distribution, which enables extremely short dwell times and thus significantly reduces the susceptibility to errors. This allows 100 percent recycled material to be processed reliably, regardless of whether the layer is foamed or compact, and regardless of whether in-house recycled material or post-consumer waste is used.


The two cover layers are also characterized by maximum efficiency and flexibility. Currently, virgin material is predominantly used here, but the design is also suitable for the use of 100 percent recycled material.


Efficient and sustainable: The new 3-layer PVC pipe head from KraussMaffei Extrusion enables the safe and stable processing of up to 100% recycled material, even with highly variable material quality.


Stable processes, big savings

The new KM-3L RK 42-HP enables manufacturers to produce much more economically. "Thanks to the largest process window on the market, long production runs with minimal downtime are possible. At the same time, material costs are significantly reduced," says Dr. Thomas Unger, Vice President Technologies at KraussMaffei Extrusion. And since material typically accounts for the largest share of operating costs, even small savings have an immediate and noticeable effect on the overall calculation.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
