In the rubber industry, small variations in ingredient ratios can have a major impact on cure rates, tensile strength, and material performance. Dosing carbon black, oils, plasticizers, accelerators, and sulfur requires repeatability, traceability, and safety—especially in high-volume or ATEX-classified production environments.
Dositech dosing systems are engineered for compounding lines that demand sub-gram accuracy, real-time material logging, and clean integration with downstream batch-off, mixer, and extrusion stages. Whether you’re producing tires, seals, hoses, flooring, vibration isolators, or molded elastomer components, our solutions deliver consistency across batches, reduce rework, and ensure production scalability.
From silica and carbon black to accelerators, antidegradants, and curatives, each dose is logged and weighed for audit-ready consistency and precise cure performance.
Enclosed transfer and grounded components reduce airborne contamination and electrostatic hazards in ATEX or OSHA-regulated zones.
Switch recipes quickly without sacrificing accuracy or requiring extensive cleaning. Ideal for facilities with frequent compound transitions or seasonal product shifts.
Centralized software stores and locks in master formulations, linked to mixer or batch call signals. Supports traceable adjustments for R&D or pilot production.
Explosion-safe dosing options built for carbon black, zinc oxide, and sulfur-based inputs in classified zones, conforming to international safety standards.
Bulk powder dosing system for carbon black, silica, and mineral fillers. Equipped for pneumatic transfer, dust extraction, and vacuum loading
Are Dositech systems safe for carbon black and silica?
Yes. Our ICON system offers enclosed, ATEX-rated operation with vacuum loading and dust control.
Do your systems help reduce ingredient waste?
Absolutely. Sub-gram dosing, real-time batch recording, and closed-loop control reduce overuse of high-cost or volatile ingredients.
Can you integrate with our internal batching or mixer signal systems?
Yes. Dositech platforms connect to batch triggers, mixers, and plant SCADA or PLC environments.
What accuracy levels can you provide?
From sub-gram (Calibro) to bulk transfer precision with ICON, each ingredient is weighed and validated before discharge.
Can your systems be used in pilot lines or R&D labs?
Yes. Calibro and Gravitas are ideal for small-scale testing with full traceability and batch repeatability.
What kind of maintenance is required between batches?
Our systems are built with CIP-ready features, smooth internal surfaces, and optional self-cleaning functions, reducing downtime between formulations.
Can Dositech systems support multiple compounds on the same line?
Yes. Our modular setups and recipe management tools make it easy to switch compounds quickly without cross-contamination or recalibration delays.
Carbon Black: A reinforcing filler used to strengthen and color rubber compounds.
Accelerators: Chemicals that speed up vulcanization in rubber processing.
Curatives: Additives like sulfur or peroxides that chemically cross-link rubber during vulcanization.
Antidegradants: Ingredients that protect rubber from aging, oxidation, or UV damage.
Batch-Off: A process step in rubber compounding where sheets of mixed rubber are cooled and dried before further processing.
