Extruders

The Industry’s Premier Extruders

What separates a Davis-Standard extruder from the competition? Our customers will tell you it’s the unparalleled performance and durability that makes the difference. Our extruders are so reliable that some are still operating after 50 years of continuous service. This track record combined with high output rates and a rapid return on investment make Davis-Standard extruders the workhorses of the industry.

From single and twin screw extruders to specialty, reclaim, medical and elastomer extruders, the depth and availability of our extruder offering is what makes Davis-Standard the global extrusion leader. We are also recognized for our coextrusion technology, supporting both vertical and horizontal coextrusion configurations.

Regardless of application or location in the world, we have the extruder to suit your requirements and budget.
