Description
Application
The DF-A automatic dose dispensing is a high-precision gravimetric automatic dispensing system designed for additive dosing in coating production, small-batch tinting, and printing ink color matching. Powered by an intelligent software platform, it integrates comprehensive functions including formula management, inventory control, and production task management. With seamless interfaces to mainstream color matching software and ERP systems, the DF-A automatic dose dispensing enables a full digital workflow from order to production.
Highlights
Achieves ±1g accuracy within a 30kg range and ±10g accuracy within a 1000kg, significantly outperforming industry standards and ensuring strict batch-to-batch consistency.
Advanced three-stage multi-flow valve design divides the dosing process into coarse, medium, and fine adjustment phases. This delivers ±0.5g precision while maintaining high throughput – only 1–2 minutes per 20L.
Built-in formula management, inventory tracking, and production task modules, with seamless ERP and color matching software integration for realtime data visibility and closedloop production control.
Flexible customization options to meet specific production line layouts and process requirements.
Available with standard control cabinet or positivepressure explosionproof cabinet, safely operating in hazardous solventbased coating and ink production areas.

System Components
The DF-A disk type dispenser system consists of:
Rotating disk structure with multiple canisters (up to 16) stores different colorants, enabling centralized material management and efficient multi-component dispensing.
Each canister is equipped with an independent diaphragm pump to deliver accurate and repeatable colorant dosing, ensuring consistent formulation results across batches.
Advanced valve design supports both high-speed bulk dispensing and fine dosing control, improving accuracy while reducing material waste.
High-precision load cell technology enables weight-based dispensing with accuracy up to ±0.5g, ensuring stable and repeatable color matching performance.
For materials prone to severe sedimentation, an optional lid-mounted stirring device can be equipped. Timer-controlled stirring keeps colorants homogeneous, preventing pigment sedimentation and ensuring consistent dispensing quality.
Intelligent control system supports formula management, automated dispensing, and real-time monitoring, enabling efficient and user-friendly operation.
Modular pump and nozzle design allows quick disassembly for cleaning, reducing maintenance time and preventing cross-contamination.
Robust industrial frame with isolated mechanical movement ensures stable operation, durability, and long service life in demanding environments.

FAQ
What is the DF-A automatic dose dispensing used for?
The Sightec’s DF-A automatic dose dispensing is a high-precision gravimetric batching system designed for additive dosing in coating production, small-batch tinting, and printing ink color matching. It is widely used in paints, inks, coatings, and chemical industries where accurate ingredient control and batch-to-batch consistency are critical for product quality.
How does the DF-A automatic dose dispensing achieve ±0.5g accuracy?
The DF-A automatic dose dispensing combines three core technologies: High-precision load cells that provide real-time gravimetric feedback; Three-stage multi-flow valve that progressively reduces flow rate from coarse to fine adjustment; and intelligent PLC control that automatically compensates for in-flight material and environmental variables.
What types of materials can the DF-A automatic dose dispensing handle?
The DF-A automatic dose dispensing supports a wide variety of container types to accommodate different production scenarios: Small pails – for lab-scale or small-batch production; 20–200L drums – for standard industrial batches; IBCS – for large-volume production. With a minimum container opening of 280mm and a maximum batch size of 1500kg, the DF-A seamlessly scales from R&D to full production.
What is the three-stage multi-flow valve and why does it matter?
Traditional two-stage valves divide dosing into “fast” “slow,” and “drop” phases. The DF-A automatic dose dispensing’s three-stage valve adds a medium-flow phase between them, enabling a smoother transition that reduces overshoot and improves accuracy. This design is the key reason the DF-A automatic dose dispensing can achieve ±0.5g precision while maintaining 1–2 minutes per 20L throughput – a balance that two-stage systems struggle to deliver.
Can the DF-A automatic dose dispensing operate in hazardous environments?
Yes. The DF-A automatic dose dispensing is available in two configurations: Standard control cabinet – for non-hazardous environments; Positive-pressure explosion-proof control cabinet – for hazardous areas where solvent-based or flammable materials are handled. Both configurations maintain the same ±0.5g accuracy and performance specifications.
