Colines of Italy (U.S. office Hauppauge, N.Y.) has made a number of enhancements to its machine-direction orientation equipment in an effort to make them more accurate and efficient. Notably:

  • The patented heating system with infrared ray heaters inside the rollers allows the orientation without any temperature dissipation, which is the most common fault of standard cylinders.
  • The IR heating system minimizes the energy consumption as well.
  • Sensors detect the temperature directly on rollers’ surfaces for a more accurate reading of the data.
  • Every roller is divided in at least three transversal zones for temperature control to ensure a perfect uniformity of the surface temperature.
  • The operating temperature is reached much faster than in oil or water systems, which means a dramatic reduction of scrap during line startup.
  • The infrared eliminates the risk of potential oil and water leakage, which represents an enormous advantage in terms of environmental sustainability as well as in terms of safety. This system is fully risk-free for potential fires.
  • The independent adjustment of the cylinders’ position, speed and temperature significantly reduce the “neck-in.”

  • Troubleshooting Melt Fracture in Profile, Tubing Extrusion

    A troubleshooting timeline is essential to help you quickly identify problems and their causes. Here we'll describe such a timeline and how to use it to solve one common problem—melt fracture in tube and profile extrusion.

  • The New Look in Plastic -- It's Paper!

    Synthetic paper based on filled polyethylene or polypropylene film has been around for decades without causing much excitement--until recently.

  • PBT & PET Polyester: Part 2 The Performance Factor

    All things being equal, PET will outperform PBT mechanically and thermally. But the processor must dry the material properly and must understand the importance of mold temperature in achieving a degree of crystallinity that allows the natural advantages of the polymer to be realized.
