Single Color Masterbatch Volumetric Dosing Machine For Plastic Injection Machine
TSD Series Screw Dosing Machine
Screw Dosers are extensively used for precise auto-proportional dosing & blending of virgin,
regrind materials, masterbatch and other various additives. The microprocessor accurately controls rate
of revolution of a motor for high precise metering with an accuracy of ±0.1% from set points.
This series can be used on the differential applications with injection molding machines and extruders.
Brushless DC motor is used for this series. The dosing screws are offered with various sizes: 16, 20
and 25 for developing diverse models with throughputs from 0.1~200kgs/hr. TOPSTAR developed
double-color & triple-color screw dosers according to customers’ various demands which can be satisfied
with diverse applications.
Features
1. Digital microprocessor can process masterbatch & regrind material by metering accurate percentage.
2. Using brushless DC motor features free from maintenance and long service life.
3. Module dismantled design, easy for change screw and sleeve.
4. The dosing unit is removed from discharging seat without material leakage, monitoring material level
from the sight - see - through window on the side of transferred seat.
5. 50 sets of parameter recipes are available for permanently recording and reading function, operating
machines quickly without adjusting parameters again.
6. Feeding base adopt different channels for material & masterbatch separately, easy change material &
masterbatch within short time.
7. Screw dosers can set metering time to avoid annoyance for unstable materbatch volume while working
with injection molding machine because of different time for every cycle of metering.
8. Forced material cleaning function is convenient to change masterbatch.
9. Material level detection sensor is available as option, alarm for material shortage.
10. It can operate with main screw of extruders, acceleration and deceleration simultaneously.
