New Technology Extrudes Rubber and Plastics — Same Time, Same Tooling

West Warwick, RI – Designed for advanced rubber and plastic applications extruded simultaneously and in the same tooling, the Syncroflow Series is now available exclusively from Guill Tool, West Warwick, RI, USA.


The plastics can be run on the inside or the outside layer because the Syncroflow tooling is designed with a barrier that insulates and separates the extruded materials from each other. This extra layer facilitates the processing of two (2) materials within a wide range of processing temperatures.


With a fully adjustable design, Syncroflow allows for separate concentricity and gum space adjustment on each of both layers. Manufactured with 420 stainless steel, the SyncroFlow design has a proven outstanding flow pattern for low volume extrusion, and all the components are designed to hold tight/close tolerances. The new Syncroflow Series is available in standard sizes from 1/8″ to 6″ in diameter.


According to Bill Conley, Sales Manager for Guill Tool, “This new technology opens a whole new world to manufacturing composites i.e. rubber and plastics, including hose, medical or specialty tubing, plus other complex composite material products. Instead of the normal two-step operation or in tandem, the Syncroflow allows a one-step process that provides excellent adhesion of materials in the molten state. Secondly, there is less chance of contaminants being trapped between the layers of plastic and rubber.” He concludes, “Saving time and money makes the Syncroflow technology invaluable in producing advanced products in today’s tough economic climate.”


Guill Tool also manufactures tips, dies, and breaker plates using state-of-the-art computerized CNC machining and EDM equipment. As well, engineering services using the latest CAD systems are available for custom-designing extrusion tooling product such as crossheads, tips, clamps, flanges, forming rolls, spiderless inline dies, dies, swing gates, breaker plates, special equipment and sizing dies.
