Syncroflow tooling from Guill Tool and Engineering Co. Inc. can extrude plastics and rubber simultaneously.
The plastic can be run on the inside or the outside later, since Syncroflow tooling is designed with a barrier that insulates and separates the extruded materials from each other. The extra layer facilitates the processing of two materials with widely differing processing temperatures.
Syncroflow is available in diameters from one-eighth of an inch to 6 inches.
By using a single die for both rubber and plastics, instead of a normal two-step process or in tandem, Syncroflow provides excellent adhesion of materials in their molten state, according to Bill Conley, sales manager for Guill Tool in West Warwick, R.I. Also, there is less chance of contaminants being trapped between the layers of plastics and rubber.
