Master Batch Dose Feeder

PNDF series volumetric masterbatch dosers are adaptable to auto-proportion mixing of new materials, regrinds, masterbatch or additives, adaptable to injection, extrusion or blow molding field. A stepper motor is used in this series, according to the set mixing proportion, the microprocessor accurately controls rotation of the high precise dosing screw to squeeze out materials with an deviation of ± 1%. The mixing precision of each batch can be controlled ± 1%. Each time the machine starts running, it will automatically check the scale to ensure the best quality. This doser can connect with various molding machine signals in synchronicity, to ensure the stability of the products.

Note:

1) ”*” means the output capacity depends on the screw selected, data of the single color doser can be a reference. For example PNDF-12, output capacity is 0.06-20kg/h.

2) “**” stands for external diameter of screw is up to model selected.

3) The output proportion of all models are 1.2, diameter 2-3mm masterbatch in a test criteria continuous running,
