Increase Production

Improve your production rates (cycle times) by more than 25% by simply changing to an improved screw design. In other cases, part reject rates have been reduced from more than 5% to less than 1/2 of 1% by utilizing a custom designed mixing screw. These facts alone illustrate the importance of the screw and its design to efficient processing performance.


Injection Molding, Extrusion, Blow Molding

Lower Costs

Screw repair consists of rebuilding the flights to the OEM diameter specification and re-chroming or re-nitriding the surface, if required. A properly rebuilt and polished injection molding screw, extrusion or blow-molding screw can be as effective as a new one and an economical alternative to a new screw purchase.
