TSD Series
Screw Dosers
Screw Dosers are extensively used for precise auto proportional dosing & blending of virgin, regrind materials, master batch 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. A brushless DC motor is used for this series. The dosing screws are offered with various size: 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.
- Digital microprocessor can process master batch & regrind material by metering accurate percentage
- Using brushless DC motor features free from maintenance and long service life
- Module dismantled design, easy for change screw and sleeve.
- 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.
- 50 sets of parameter recipes are available for permanently recording and reading function, operating machines quickly without adjusting parameters again.
- Feeding base adopt different channels for material & master batch separately, easy change material & master batch within short time.
- Screw dosers can set metering time to avoid annoyance for unstable mate batch volume while working with injection molding machine because of different time for every cycle of metering.
- Forced material cleaning function is convenient to change master batch.
- Material level detection sensor is available as option, alarm for material shortage.
