Santa Fe Machine Works is the Only Manufacture for Posi-Melt Custom Injection Screws

Injection Screw Design For Optimum Mix and Reduced Cycle Times

With nearly a century of experience, we know general purpose profile and substrate screws rarely meet the demands of ever changing polymers & resins. Using GP screws in state-of-the-art machinery is like putting cheap tires on a fine race car.

To compliment our high performance injection screw designs, we are proud to offer Posi-Melt Technology. With a superior mix that produces 100% true vibrant color, Posi-Melt applications meet the most demanding melt quality and cycle times in the industry.
