Guill Tool & Engineering Co. Inc. said its MediFlow tooling can turn out ultrathin-tolerance medical tubing that is finer than a single human hair — with tolerances of just 0.002 inch.
The tubing is used for minimally invasive surgical procedures.
MediFlow includes a new head and in-line dies.
* Head deflectors that are compacted, with a short axial length, so they are optimized for minimum material residence time and pressures.
* A patented spiral design for thermally balancing the melt far upstream, so the velocities flow equally for the maximum possible length. That produces a very close-tolerance, multilayer tubing.
* The flow in the body can be either a split flow or Guill's new, patent-pending single-flow feed.
* A patented FeatherTouch design allows for easy adjustment of concentricity, without choking off the upstream flow.
In other news, Guill said its crosshead design has enabled extrusion companies to make hose, tube and pipe that complies with California's Proposition 65 environmental law covering safe drinking water and toxic chemical release.
In response to requests for help by a major U.S. garden hose manufacturer, Guill developed a crosshead die that coextrudes hose with two very thin layers of virgin polymer surrounding an inner layer of less-expensive regrind.
