Gravimetric Doser
Key Features
Adopt stainless steel screw, reliable and durable.
Adopts high – precision hybrid stepping motors, has accurate and stablefeeding, and a speedy response.
Modular assemblystructure, easy to disassemble and assemble, easyto clean and swap parts.
With forced cleaning function to facilitate the replacement of master batch;Lively recording the current running mode, which is not affected bypower outage and will resume running once power restored.
With functions to transmit data for communication, and export data forchecking production running condition.
Loss-in-weight weighing technology is adopted to control the mixing process, which can meet extremely high production accuracy requirements.

Application
Gravimetric Doser adopts high-precision hybrid stepping motor and PLC control, which can meet the high accuracy requirements for proportional adding of plastic components in injection molding orextrusion productions.
lt is suitable for automatic proportional mixing new materials, scrap materials, master batch or additives, etc.
Also, depending on actual condition, dual color volumetric doser is optional.
Besides, auto loader for auto re-filling masterbatch is also available.
