Precision Metering and Dispersion System for Liquid Color Concentrates: Achieving Accurate Coloring and Efficient Production
In the coloring process of plastic products, precise dosing of liquid color concentrate is the core link to ensure color consistency and production stability. Our high-precision metering system integrates two precise solutions—gear pumps and screw pumps—paired with a continuous and gentle stirring device to maintain uniform concentrate concentration, fundamentally achieving high inter-batch color consistency.
Metering Solutions Adapted to Different Production Scenarios
For production lines that require frequent color changes, we recommend using a gear pump metering system. This solution allows for quick color switching by simply replacing the TPE tubing during changeovers, significantly reducing cleaning and downtime while markedly improving production line flexibility and efficiency. It is suitable for coloring needs with conventional addition rates of 0.1% to 0.3%. For scenarios involving long-term continuous production with extremely high demands on dosing accuracy, the screw pump metering system can achieve stable addition with higher precision, reaching a minimum addition rate of 0.03%, ensuring color uniformity while effectively reducing coloring agent costs.
Comprehensive Value and Process Advantages of the System
Our metering system enhances production efficiency and significantly reduces raw material waste through automated, precise addition, minimizing the uncertainty and frequent intervention associated with manual operation. The built-in continuous stirring function effectively prevents pigment settling, ensuring uniform concentrate concentration. Furthermore, its modular design and closed-loop control system enable flexible adaptation to various production equipment, allowing real-time monitoring and automatic adjustment of the addition ratio to calmly handle process fluctuations.
Measurable Production Benefits
The application of this system can stabilize the color deviation ΔE value below 0.3, achieving excellent color consistency. Meanwhile, color matching time in production can be reduced by 30% to 50%, and the usage of coloring agents can be lowered by 15% to 25, leading to significant cost savings and efficiency improvements while enhancing product quality. The system can stably process recycled materials and scraps, effectively overcoming their impact on the final color and ensuring long-term production stability.
We are committed to helping customers achieve full-process color control from color matching to production through precise and reliable coloring metering solutions, especially suitable for applications with stringent requirements on color consistency such as food packaging, high-end consumer goods, and medical packaging.
