MELT FLOW INDEX TESTER
Consists of a heated extruder tube, removable jet through which the material under test is extruded, a piston and dead weights to apply the specified pressure on the material inside the extruder tube.
Extruder tube made up of hardened die steel, a PID type digital temperature indicator cum controller is provided to indicate & control the temperature of the tube accurately.
A cylindrical cavity is provided in the extruder tube for placing the test charge the test charge in during the test.
Description
Melt Flow Index Tester
The Melt Flow Index Tester GTX-YB8 is laboratory testing equipment consisting of a heated extruder tube through which the material under test is extruded. The equipment uses a piston and specified dead weights to apply pressure to the material inside the extruder tube during testing.
The extruder tube is made of hardened die steel and is provided with a removable jet through which the test material is extruded. A PID type digital temperature indicator cum controller is provided to indicate and control the temperature of the extruder tube.
A cylindrical cavity is provided inside the extruder tube for placing the test charge during the test.
Working Components
The Melt Flow Index Tester consists of:
- Heated extruder tube
- Removable jet
- Piston
