Melt Flow of thermoplastic material is defined as the rate of flow in grams per ten minutes of extrudate of molten resins through a jet of a specified length and diameter under prescribed conditions of temperature, load & piston position in a cylindrical cavity inside a heated metallic tube barrel at the measurement is being made.

  • The ASIAN Melt Flow Index Apparatus for Plastic consists of a heated extruder tube, an interchangeable jet through which the material under test is extruded, and a piston with dead weights to apply the specified pressure on the material inside the extruder tube.
  • The extruder tube is made from carbon steel and is heated by means of a Bend Heater, which surrounds its outer circumference. A PID controller is provided to indicate & control the temperature of the tube. The tube has a hole parallel to its bore for placing the thermocouple junction. The heater logged with mineral wool insulation. The assembly is fixed on a rigid stand. The bottom of the tube is lagged with a 3 mm thick insulation of PTFE to prevent sticking of the extrudate.
  • The jet through with the extruder is pushed out is made from hardened and ground die steel. It is held at the bottom of the extruder tube.
  • The piston made from silver steel relieved at the upper end is provided to push the extrudate out of the jet. The piston moves inside the cavity of tube. A sleeve to provide to guide the relieved portion of the piston. The top of the piston carries a plate-form for keeping the load on. The plate-form is thermally insulated from the load.
  • The extruder tube assembly is mounted on a metal box. A sheet metal control panel is mounted on the side of the equipment & houses the PID Controller, DIGITAL PRESET TIMER @other electronic components.
  • Cleaning tools for tube cavity and jets & stoppers & cutter for the extrudate are also supplied with the equipments.
