● Compact, light weight and desk top.
● The center of the equipment (Fiston, Cylinder, Die etc.) is unit-defacement and longterm stable.
● The piston holder, attachable tool holder and the stop watch holder are better for operation.
● Optionable various weight load is available for all of measurements.
● The excessive temparature prevent, electric leakage breakar, fall down prevent etc. are safety devices.
Method A (Manual cutting method)
The resin which flows out of die within the specified time is cut off and the weight of cut portion is measured, and then the melt flow rate (MFR)
－the amount flowed out in 10 minutes － is calculated. MFR is calculated by the following equation as the Mass (g) of the sample extruded in 10 min.
AFR (T * M * A) = (600 * m) / t
where
T: Measuring temperature (℃)
M: Test load (kg f)
A: Operation of Method Ａ
m: Mean value of Mass of extruded sample
t: Time required to take sample
600: 10 minutes counted in seconds
Method B (Automatic time measuring method)
The time required by the piston to move down the specified length is automatically measured, and then the value of MFR is calculated by using
the time thus obtained. For the Method B, the MFR Automatic Operator (option) used. MFR is obtained by the following equation
MFR = ((427 x L x d) / t) g/10min
where
L: Actually measured travel length cm3
d: Resin density g/cm
t: Travel tim sec
