Doser, 1.controlled by microcomputer, 2.used for precise auto proportional dosing, 3.stainless steel casting has long life - details see: https://www.machineto.com/single-color-plastic-volumetric-doser-10338700

single Color Plastic Volumetric Doser

1.Specifications

Serial screw doser is suitablefor extrusion machines and injection machines. Stepper motors of high accuracy are installed in this device, when the signal stops, it generates braking immediately to prevent motors from inertial moving. Accuracycan be set up to 1/100.Microcomputer processing controller have LCD display and measurement set, which can measure the proportion of masterbatch and material added. And can set the times of operation and speed per minute to match screw rotation period, the screw rotation speed can be set bythe range of 1 to 300 rpm.

Serial screw doser contains blanking base, the metering screw group,stainless steel materials and controlleretc. This machine and the molding machine materials tube must be installed with the direction of 90 degree to prevent motor function affected by heat adverse.

2. Main features

1)Stainless steel casting has long life

2)The system is controlled by microcompute

3)Using the Quick Change concept design for quick and easy replacement of the screw and sleeve

4)Precision screw and sleeve design can correctly measure the ratio of the masterbatch and raw materials

5)Overall design to meet the safety requirements

6)The speed of the screw can be set to a range of 1~300RPM
