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.RELATED STANDARD :ASTM-D- 1238 – 1982 : Standard test method for flow rate of Thermoplastic by Extrusion Plastometer.

Cupping testing machine is widely used in sheet metal industries for determining the ductility of the metal sheets. This test helps you analyze the level of deformation on sheets when they are subjected to an amount of pushing force. It is also used to analyze the quality of paint which are applied to the metallic substrates for protecting the latter from environmental damage. With the help of this test, the paint manufacturers can easily evaluate the elastic properties of the paint and study the development of cracks in the surface coating once they are stretched with the substrate on applying force.

The melt flow index tester (Deluxe Model) is a significant attribute of any plastic material that can help in determining various chemical and physical properties of the materials. The melt flow index tester is a highly precise and accurate instrument that offers exact and accurate determination of melt flow index of a plastic resin. The melt flow index of a plastic resin is termed as the weight of the resin flowing through a capillary tube every ten minutes under an unambiguous load or shear stress. The test procedure includes passing the molten plastic granules from a capillary tube of specific dimensions. A specified load is applied to the test sample with the help of a piston. Apart from that the following are also available for the customers - Melt Flow Index NXG Model. The melt flow index tester is used for determination of the melt flow rate of various materials such as plastic granules. It is a widely used product in plastics and polymer industry. The instrument is designed and manufactured as per standards set by ISO and ASTM and is mainly focused on meeting the principal conditions necessary for the test procedure. The instrument has a PID temperature controller, and its working is based on a microprocessor. The temperature can vary from ambient to 4000C. The resolution of the instrument is also 0.10C and has an accuracy of ±0.10C. The apparatus comes with a digital timer that is pre-settable and can be extended to 59 minutes and 59 seconds. There are standards accessories available with the devices that are a piston, orifice, spanner, funnel, spoon, mirror, plumb line, material charger, barrel cleaners and so forth. The machine is manufactured on a base plate of heavy metal for long life, safety and stability. The tester is in strict adherence to standards of ASTM D 1238-1992. The instrument has a fine finish in grey and blue color. The product comes with a complete user guide and a conformance certificate that can easily be traced to any labs approved by NABL. Features: The instrument is capable of maintaining the accurate temperature needed for the test procedure that ranges from ambient to 400 0C. The temperature controller used in the machine is PID which is a completely microprocessor based. The machine has a high rate of accuracy and repeatability and incorporates a pre-settable timer. The instrument has a feature to cut the test samples automatically which makes the results reliable and test procedure easy. Additionally, the standard accessories and resources are available with the product.
