We offer a wide range of Melt Flow Index Tester widely used to determine the melt flow index of plastic material. This system is structured with a heated extruder tube, an interchangeable jet and a piston with dead weights. This piston is used to apply the required pressure on the material inside the carbon steel extruder tube. A Bend Heater is affixed around outer circumference of the extruder tube and is used as an effective heating material. This heater is covered with a mineral wool insulation. The extruder tube is installed with a PID controller to indicate & control the temperature. Manufactured in accordance to the ASTM D 1238 & equivalent standards, this range of testers is available in various models with different parameters.
Construction of the metal flow index tester:
The assembly is fixed on a rigid stand.
The bottom of the tube is lagged with an insulation of PTFE to prevent sticking of the extrudate
The jet through which the extruder is pushed out is made from hardened and ground die steel
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 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, jets, stoppers and cutters for the extrudate are also available with the equipment.
The top of the piston carries a plate-form for keeping the load on.
Polyplast make Melt Flow Index Tester helps to find the MFI value of the polymers.
The tester is with full ancillaries, are part of the unit.
The Auto cutting facility is aunique feature of this model, which will start cutting the extrude on predetermined intervals and will make sure the final result free from technician’s skills.
PID type temperature controller makes sure very accurate and uniform Temperature.
