In small size extruder test of Labo Plastomill, in addition to detecting torque, the pressure and temperature (maximum 4 points each) are also continuously detected during molding by installing resin temperature sensor and resin pressure sensor in the cylinder or die and the values are displayed on the monitor. Various kinds of molding dies and take-off devices are also available, allowing you to determine molding conditions by simulating and obtain various information such as pressure, temperature, torque, specific energy (MJ/m3) and extrusion amount at each rpm (each shear rate) in addition to detecting mold status such as extrusion mold product’s fish eye, dispersion, transparency and gloss by using a small quantity of sample.
Example of application
Simulation test using various kinds of molding die head
Viscosity measuring test by slit die (measuring apparent and true values of shear rate, shear stress, viscosity)
Specific energy measuring test (evaluation of productivity)
Filter pressure resin test (measuring gel substance in resin)
Die swell measuring test (resin(s elasticity recovery swelling test)
Melt strength test (measuring melt tension and breaking speed)
Garvey die test (ASTM D 2230, rubber moldability evaluation)
Compounding and pelletization
Fixed quantity extrusion test by gear pump (pressure/revolution control)
Inflation take-off bubble tension measuring test (Take-off device with tension measuring device)
