▲ Unit is comprised of standard modules for ease of cleaning,disassembly and interchangeability; ▲ Using the high accuracy hybrid stepping motor, measurement accuracy and output scope; ▲ Motor drive directly, without gearbox, long service life,Maintenance-free; ▲ Microprocessor control, intelligent and accurate in calculation; ▲ Everlasting data memorizer and settings storage, ▲ Dosing screws are chrome plated for durability, ▲ The roof-shaped quick-change (the dosing section can be removed without granulate leaking form the neckpiece),large opening on the side of the neckpiece, large window and improved static blending.
WHVD series volumetric dosers are suitable for auto-proportional mixing of new materials,regrinds, masterbatch or additives, suitable for 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 accuracy of ±1%.This doser can connect with various molding machine signals in synchronicity, to ensure the stability of the products.
