Volumetric Doser

A volumetric doser is a precision-engineered feeding device widely used in industrial production, primarily designed to accurately meter, convey, and dispense granular, powdery, or pelletized materials at a consistent volumetric rate. Unlike weight-based dosing systems (e.g., gravimetric dosers), it operates by measuring the volume of materials—leveraging fixed-displacement mechanisms to ensure repeatable feeding, making it a cost-effective and efficient solution for continuous or batch manufacturing processes.

The Two-color Volumetric Doser is a high-precision auxiliary equipment designed for plastic injection molding, extrusion, and blow molding processes. It integrates dual independent volumetric feeding systems in a compact structure, enabling accurate, simultaneous metering and feeding of two different materials (e.g., virgin resin & recycled material, base material & additive, or two distinct color masterbatches). Engineered to optimize material distribution, reduce waste, and ensure consistent product quality, this doser is an essential tool for manufacturing two-tone, multi-component plastic products or enhancing material performance through precise additive blending.
