Extrusion tubing manufacturers/OEMs are welcoming a new and unique six-layer head/die from Guill Tool & Engineering Co. This technology offers a host of benefits that include a lower cost for a single six-layer system as compared to purchasing two three-layer systems or three two-layer systems that perform precisely the same function.
Other benefits of the six-layer Series 800 include the ability to extrude fluropolymer materials, which have superior qualities and resistance to fuel blends, UV, heat, and chemicals. The six-layer can also handle non-fluropolymers and adhesives that work well when combined in thin layers (0.02 mm or less) with new head/die tubing end products. With the design of the six-layer by Guill, all inner layers are totally encapsulated to avoid any possible contamination of the tubing itself.When engineering the Guill six-layer design, computer simulations of the flow channels using Computational Fluid Dynamics (CFD) programs allow the properties of the exact material to be used with the exact geometry of the die. The simulations are aimed at generating a uniform flow with even wall thickness and no weld lines.
