pipe and profile

From coaxial cable to refrigerator gaskets, we've designed feedscrews optimal for stability, mix and high output. 

Sheet Extrusion

We have extensive experience designing ABS, PE, PP non-vented, vented and double-vented feedscrews that have eliminated surging, produced a more consistent mix and greatly reduced the need for pre-drying.

Compounding & Recycling

When high output and homogenous mix are what you are looking for, TIR has designed large diameter (3.5" to 13") feedscrews that have significantly increased output and reduced wear.
