Measuring Single-screw Extruders for Labo Plastomill | 655
Toyo Seiki · Mixing & Kneading / Extrudability / Stretching
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.

| Gravimetric feeder | WCF-1R/WCF-1L | The feeder is placed on an electronic balance, the weight of the sample to be discharged from the feeder is weighed from the overall feeder weighing value, and the screw rotation of the feeder is controlled to provide a fixed-volume feed. |
| Forced feeder | FH2 | The lower part of the agitator blade in the hopper is screw-shaped, and a variable-speed motor forces the sample into the hopper. / Funnel-flow, rat-hole, bridges, etc. occur in the hopper can be suppressed. |
