Graham Engineering’s innovative and high value extruder family is available in 16 sizes and customizable to suit your industrial tubing needs.

Each machine includes a complete spare parts package and is backed by our protection plan which includes a three-year warranty and comprehensive wet testing before shipping to your facility.


No matter what size tubing you need to produce, our American Kuhne machine is up for the task. Not only does the operator retain control of the system with the standard Navigator control system, each model features design enhancements. These include pluggable barrel thermocouples, switchable die-plugs, fuses instead of circuit breakers, and rapid configuration and customization.

Graham Engineering uses parts that are compatible across different models to make repairs and maintenance easy and cost effective for you.

Downstream Equipment

The ULTRA extruders built, tested, and maintained by Graham Engineering are specifically designed to create your end product. In order to ensure consistent performance, we offer proven technology and high-quality components in every customized extruder machine.

Our testing includes validation of mechanical and electrical functions, programming and testing of the pressure indicator, auto-tuning of the temperature controllers, and full configuration of the drive parameters. We do all this to give you the fastest and smoothest start-up possible after delivery.

The state of the art American Kuhne extruder machines incorporate an advanced Navigator system that gives you one of three levels of control.

The XC100 Navigator is for a single extruder operation that is fully functional and streamlined for the system. The XC200 Navigator expands that functionality to cover one or more extruders running simultaneously. And the XC300 is our most robust system that provides intelligent control over multiple component extrusion systems.

No matter which set up is appropriate for your production needs, Graham Engineering has a system to accommodate.
