Standard Repair

In most cases, twin screws can be rebuilt at a considerable cost savings over replacement. Individual elements can be replaced as necessary. In addition, we can change element order, add or eliminate mixing and kneading sections and provide general optimization of twin screw profile. Services for Plastics, Inc. can also check twin screws for shaft straightness and shaft twist.

Replacement elements can be manufactured from D-2 Heat Treated Steel, CPM-9V Heat Treated Steel or CPM-10V Heat Treated Steel for maximum abrasion resistance.

Process Improvement and Enhancement

When having problems with increased scrap and decreased throughput, SFP is your answer. Our engineers have over 50 years of combined twin screw experience. We have the capabilities to understand your unique application and to assist in the design that will yield the highest throughput with the best melt quality. For high shear, low shear, large throughput and high RPM speed, we have your answers.
