Dosing Systems
Precise dosing and blending for repeatable recipes.
Gravimetric batch blenders, volumetric dosing machines, and liquid dosers meter additives, masterbatch, and regrind material with high accuracy, securing your production recipe.
- 01
Each component is metered into a weigh hopper by a screw or slide gate.
- 02
Load cells verify every dose against the recipe in real time.
- 03
The mixed batch is homogenized and released to the machine throat.
- 04
Closed-loop correction adjusts the next dose from the measured deviation.

Frequently Asked Questions
What is dosing in plastics?
Dosing is the process of adding the correct proportion (by weight or volume) of color, additives, or regrind material to the raw polymer as required by the production process.
What is the difference between gravimetric and volumetric dosing?
Volumetric dosing relies on volume calculations over time, whereas gravimetric systems use integrated load cells to measure the actual weight of the material, providing much higher accuracy (±0.1%).
