YOUR PROJECT - OUR PRECISION

Your Screws Should Match Your Goals

Did you know that processing problems during extrusion or injection molding can be caused by a screw that is not optimally matched to the application? Screw variations are designed to achieve a special processing result. So, choosing the right screw can already improve your production rate and reduce your part reject rates. There are many mixing screw designs offered that can provide both dispersive, distributive or a combination of both, that result in the reorientation of the resin after it has been melted. Together we will find the perfect individual solution for you so you can reach your production goals.

REILOY USA EAGLE® MIXING 

The Unique Reiloy USA Eagle® Design Concept

Our Eagle® and Eagle® Barrier screws continue to set a very high-performance standard by supplying a predictable, repeatable performance that can be counted on day in and day out. In addition to the High-Performance Eagle and Eagle Barrier Mixing screws, we also offer a wide range of mixing screw and mixing element options for both the injection and extrusion industries.

Established in 2015
Our patent mixer features five levels of adjustability

Versatile Configuration
Variable adjustments allow the screw to function as either a low-shear or high-shear mixer

Broad Material Compatibility
The design is suitable for processing diverse resins, from ABS to nylon

Enhanced Processing Applications
Applicable to injection molding, extrusion, and more, the mixer improves mixing quality without excessive shear, boosting profitability

Something to look forward to

Highlights of Your Reiloy USA Screws

Best Wear Protection

To ensure you get the best wear protection, we produce our hard alloys inhouse. We work closely together with machine and raw material manufacturers, and with universities.

Top Product Quality

We optimize the design of plasticizing units, select the most suitable material pairings, and support you to obtain the best economic efficiency and functionality for your new design.

Maximum Productivity

  • Screw geometries matched to the application
  • Perfect barrel/screw combinations
  • Long maintenance intervals

Large Sizes

We manufacture screws to lengths up to 9 meters.

Eagle Mixer 

The Eagle® is a low shear, distributive and dispersive mixing screw that provides the processor with outstanding color mixing and melt quality – all without increasing melt temperature, burning or degradation while running at very high RPM.

The Eagle® is used with custom designed single-flighted screws and also with barrier designs for special applications.

IMPROVE THE COST-EFFECTIVENESS OF YOUR PLASTICIZING UNIT

High quality with top-class wear protection

Reiloy USA manufactures screws in a variety of steels. Surface treatments such as gas or ion nitride, or hard chrome plate can be added for additional surface protection. With our expertise and experience, we design screws specifically to increase the efficiency of your production processes and applications.


Securing product quality and process stability sustainably.

Top-class Wear Protection

Reiloy USA manufactures screws in a variety of steels. We can add surface treatments such as gas or ion nitride, or hard chrome plate for additional surface protection. With our expertise and experience, we design screws specifically to increase the efficiency of your production processes and applications.

Material Designation

We choose between heat-treated and hardened condition tool steel, alloy steel, 4340 series or special alloys such as Hastelloy C-276, etc.

Secondary treatment to provide wear resistance

Some materials are either chrome-plated, nitrided or heat-treated.

Flight hard-surfacing

Screws that are not manufactured from solid or stainless tool steels need a flight hard-surfacing material such as: Stellite 6 or 12, Colmonoy 56,57, or 83, etc.
