Color masterbatch formulation demands precise pigment ratios, consistent dispersions, and traceable batching to ensure color accuracy and compliance. With high resin volumes, dense pigments, and complex additive blends, even a small formulation deviation can result in product rework, scrap, or off-spec coloration.
Dositech systems help masterbatch producers scale efficiently without sacrificing quality. Our dosing platforms automate powder and liquid weighing with sub-gram precision, enable rapid changeovers, and integrate seamlessly into production lines from compounding to extrusion.
Accurate measurement of dense and fine powders, including black carbon, titanium dioxide[1], and fluorescent pigments.
Ensure exact ratios across every batch to maintain opacity, dispersion, and polymer compatibility.
Enclosed weighing and transfer prevent airborne pigment loss and cross-contamination.
Integrated software records every batch variable for audit-ready compliance.
Expand from a few pigments to dozens with scalable mono or multi-scale configurations.
Our systems help pigment, additive, and polymer workflows move from formula to extrusion with precision and speed:
Compact powder/liquid dosing for labs or pilot lines. Ideal for new formulation testing or high-value batches
Accurate liquid carrier dosing with integrated mixing. Supports high-viscosity blends and liquid pigments
Can Dositech systems handle high-density pigments like black carbon?
Yes. Our ICON and Calibro systems offer enclosed, vacuum-assisted loading to prevent dusting and dosing errors with dense powders.
Do your systems support automatic color changeovers?
Yes. With scalable modules and smart software, Dositech platforms enable faster transitions between formulas and materials.
Are your systems safe for ATEX environments?
Absolutely. Our dosing hardware includes ATEX-certified options and features grounded for electrostatic safety.
How do you ensure batch-to-batch color consistency?
Our systems deliver sub-gram accuracy and software-driven recipe locking, ensuring pigment ratios remain exact across every run.
Can we integrate Dositech with our existing extrusion or SCADA system?
Yes. All equipment is SCADA-, ERP-, and MES-ready with full digital I/O and recipe control.
