The melt flow tester produced by Wewon adopts a new generation of artificial intelligence instrument temperature control and double-position time relay output control. The constant temperature cycle of the instrument is short and the overshoot is extremely small. The temperature control part adopts a “non-burnable” thyristor module. So that the temperature control accuracy and product stability can be effectively guaranteed. In order to facilitate the user’s use, this equipment can realize manual, automatic and time-controlled three test methods for material cutting (the cutting interval and cutting time can be set arbitrarily).
Melt flow index tester from Wewon Environmental Chambers Co., Ltd. is very intelligent and highly automated. The inside of the machine adopts high-performance and high-precision control instruments, and uses PID adjustment for constant temperature control. It has high sampling accuracy, fast heating speed, high product accuracy, and stable and reliable performance.
The melt flow rate refers to the mass or volume of the thermoplastic melt passing through the standard die every 10 minutes under a certain temperature and load. Melt flow rate index tester is an ideal testing and teaching instrument for plastic raw material and plastic product manufacturers, quality inspection supervision and inspection institutes and colleges and universities.
