Feedscrews
The critical component of any extruder is the feedscrew. If perfectly matched to your process, the result is optimum output and a quality product. Davis-Standard stays on the leading edge of screw technology with one of the most advanced design and manufacturing facilities in the world.
All Davis-Standard feedscrews are designed and manufactured right on the premises. Designs are based on individual customer extrusion parameters encompassing output rate, melt temperature, output consistency of extruder stability, melt homogeneity, melt quality, and power requirements.
Single Screws
