Fully automatic melting finger tester

Fully automatic melting finger tester

This model is high-precisionFully automatic melting finger testerIt is used to determine the MFR value of various plastics and resins in a viscous flow state through a certain temperature and load, passing through a standard die melt flow rate every 10 minutes. It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, fluoroplastics, nylon, etc. with high melting temperatures, as well as for testing plastics with low melting temperatures such as polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM), polycarbonate (PC) resin, etc. It is widely used in plastic production, plastic products, petrochemical industry, and related institutes

1. Fully automatic loading weight melting finger instrumentMulti stage (five stage) temperature control method, five sets of platinum resistance sensors, five heating sleeves for individual temperature control, high-precision intelligent PID regulation, adjustable heating slope or heating speed
2. The fully automatic loading melting finger instrument has a temperature resolution of 0.1 ℃, a temperature uniformity of 0.2 ℃, and a temperature fluctuation of no more than 0.5 ℃ within 24 hours. The displacement sensor has a resolution of 0.001mm.
3. Built in melt index analyzerTemperature over temperature protection device
4. The melt flow tester integrates manual and automatic cutting, and can set the cutting time (0~999) and cutting frequency (0~999) arbitrarily
5. During testing, the quality method, volume method, or both testing methods can be selected, and the flow rate ratio can be calculated. Both methods start testing when the piston rod moves to a certain position.
6. The melt flow rate meter has a built-in temperature stability alert and an additional 240 seconds (as specified in GB3682) countdown for material preheating. After the countdown ends, a prompt sound will be emitted, and preheating times such as ASTM can also be set.
7. Melt dissolution index meterBuilt in multiple plastic material melt index testing conditions, convenient for customers to access and use at any time, reducing tedious workload, and storing the latest testing conditions and results for the next test
8. Fully automatic melt flow rate meter with built-in micro printer for easy printing of test data
9. High precision touch screen controller, 7-inch touch screen, capable of storing and printing up to 50 (or 20 sets) of test conditions and data. The test printing menu settings include test time (system default), operator, material name, test method, test conditions (temperature, weight of weights, cutting time interval), test result data, and manual judgment of test results as OK or NG,
10. Reserved RS232 interface or USB interface for connecting to a computer, which can control instrument operation and transfer and save test data to the computer. It can be retrieved according to certain conditions, such as by testing time, all test results between two time periods, or by the name of the testing personnel or material or whether the test results are OK. Then, some statistical functions such as drawing histograms, scatter plots, etc. can be added, and multiple instruments can be connected through one computer.
11. The fully automatic melt flow rate meter can manually load weights or use a stepper motor to drive the ball screw to rotate, in order to achieve automatic control of the top loading weight's rise or fall
