Highly wear-resistant bimetal barrels and screws for injection molding and extrusion.

Highly wear-resistant screws and barrels raise the productivity of your production lines and improve the quality of the end products. With know-how, experience and the right technologies we reliably protect your components against abrasion, adhesion and corrosion.

Highly wear-resistant screws

Highly wear-resistant screws will not just extend the service life of your plant. They will also improve the quality of your products. We can offer you all kinds of screws for extrusion and injection molding: 3-zone screws, multiple-thread screws, barrier screws, vented screws, or highly complex twin screws.


Highly wear-resistant barrels

Reifenhäuser Reiloy top-quality alloys for bimetallic barrels ensure optimum protection from wear and corrosion in production. Blanks are 100% distortion-free – even with lengths of ten meters. This is because they are manufactured using centrifugal induction casting systems with integrated process control, which were developed in-house.


Bimetallic twin barrel

With a combination of different bimetallic alloys, we apply our wear protection exactly where it is needed in your production process: heavy-duty wear protection for the high-load areas of the barrel, more affordable wear protection for less heavily used areas – for high productivity and low maintenance costs.

Twin barrel

Own gas atomizing system for the production of powder

As regards the production of Reifenhäuser Reiloy hard alloys, we have come up with our own process using powder atomization. The gas atomizing system can be found at our site in Troisdorf. Where further development is concerned, we cooperate closely with machine builders, raw material producers, as well as universities and colleges.

Research & Development

Eroding complex designs

Using a specially developed process and a 5-axis CNC erosion machine, we can make exhaust bores, pressure transducer bores, feeding pockets, feeding grooves, and technically demanding geometries like conical helix grooves.

Optimal specifications for plasticizing units

We are a manufacturing company, but primarily we are a competent consultant. We use our expertise in engineering and metallurgy to find optimal specifications for plasticizing units, select suitable material combinations, and support you in your development of new barrels to improve profitability and functionality.

Amazing facts
Would you have guessed that?

1.910 °C
is the melting point of the refractory metal vanadium. Reifenhäuser Reiloy however manages to melt this metal at 1,800 °C.

i.e. 100 times the acceleration of gravity, is the level of centrifugal force applied during centrifugal casting. By way of comparison: Fighter jets are subject to approx. 10g.

10.000 °C / second
is the cooling rate with powder atomization. Reifenhäuser Reiloy uses this process to manufacture metal alloys in-house.
