Melt Flow Index Apparatus determines the flow of a given molten mass of a plastic sample. It is one of the important quality assurance parameters in inwards testing. The extrudates are cut off at a uniform time interval to ensure accuracy that complies with international standards. It determines the distance the piston containing the sample travels in a given unit of time.

Smoke Density Tester is constructed using 14 gauge aluminum box, which is hinged a heat resistant glass glazed door. This box is mounted on the base which houses the controls. Dependent upon the materials tested, the metal may require protection from corrosion. From the same rod similar bezel is located below and it is support a square of asbestos paper which catches any particles that may drip from the specimen during the test.

Technical specifications:


  • ASTM D: 2843
  • The chamber is sealed except for 25 by 30 mm (1 by 9 in.) openings on the four sides of the bottom of the chamber.
  • A liters/min specified capacity blower is mounted on one side of the chamber.
  • The inlet duct to the bowler is equipped with a close fitting damper.
  • The outlet of the bowler will be connected through a duct to the laboratory exhaust system.
  • The two sides adjacent to the door are fitted with 70 mm (2/3in) diameter smoke tight glazed areas entered 480 mm (19/4 in.) above the base.
  • At these locations and out side the chamber, boxes containing the optical equipment and additional controls are attached.
  • A removable white plastic plate is attached to the back of the chamber.
  • There is a clear area centered above the bottom of the chamber.
  • Through which is seen an illuminated white on red exit sign.
  • The white back ground permits observations of the flame, smoke, and burning characteristics of the materials.
  • The viewing of the exit sign helps to correlate visibility and measured values.
  • The specimen holder is supported on a square gauge.
  • Stainless steel wire cloth above the base and equidistant from all sides of the chamber.
  • This screen is lying in a stainless steel bezel supported by a rod through the right side of the chamber.

Smoke Visibility Tester made of a plywood chamber inner side painted by heat proof paint the ceiling of the chamber have a hole which permit to hold light meter cell while testing. There is a hole in the bottom of the chamber, which is aligning to the ceiling hole. There is a clear glass bulb fitted to the bottom hole. Left-hand side of the chamber has a hole, an exhaust fan fitted to the left hand side hole. Right hand side have hole which permit to flow air at the time of the exhaust of the smoke to the chamber. The front of the chamber has a hinged door, which have a clear glass window on the door. There are shutters on the left hand side and the right hand side hole of the chamber. The LUX of the bulb control with the help of an electronics regulator fitted in the panel of the instrument. The ceiling hole and the front glass window covered with the black curtain. The chamber fitted on the section stand. A LUX meter is supplied with the instrument for the measurement of the LUX of the light. There is a aluminium silicate and a stainless steel plate also supplied with the instrument. There is a stainless steel specimen frame tilted at 20?a to the vertical and have the provision to hold the specimen and there is provision to slide the specimen frame. There is a burner mount on the bottom of the chamber at an angle of 45. A flow meter, pressure gauge and pressure regulator are fitted on the section frame for the adjustment of the supply of the gas. All the parts are painted or polished for the corrosion resistance long life. We will not supply the any gas with the instrument.
