Melt Flow of thermoplastic material is defined as the rate of flow in grams per ten minutes of extrude 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.
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 whole 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 extrude. 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 extrude 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 at other electronic components. Cleaning tools for tube cavity and jets & stoppers & cutter for the extradite are also supplied with the equipments.

Tensile strength and elongation are the two prime characteristics of most of the raw materials, whether they are metals: or non-metals: such as foam, rubber, textiles, plastic, paper: or finished products such as rods, wires, ropes, yarns, belts etcetera. These properties very often play the major role in determining the suitability of any raw material for any specific application. It is therefore, of utmost importance to determine these characteristics accurately, conveniently, and quickly.
Tensile Testing Machine provides a relatively inexpensive way for determining the tensile strength and elongation of variety of raw materials such as rubber, leather, fabric, plastics, Belts, wires etcetera. They are based on constant rate of traverse principle in which one end of the test specimen is held in a stationary grip, while the other end is made to move at a known fixed speed with the help of motor, gearbox and screw arrangement. The load exerted on the stationary grip is sensed by a load cell and indicated by a digital load indicator. The controller is microprocessor based and has the facility of over load protection, peak hold and auto calibration. The load directly indicated in kilograms or Newton.
The elongation of the test specimen is measured on a digital indicator fixed on the frame of the tester, which indicates the distance between the grips. The frame of the tester fabricated from heavy mild steel sections to give the required rigidity and strength. Various built in safety arrangements such as over travel protection are provided.
The tester is finished in metallic painting and bright chrome zinc plating to give the apparatus a corrosion resistant finish. It is supplied complied which electrical. Which include micro-, switches, Push buttons, and contactors for safe and convenient operation.
