Automatic Paint Filling Machine with Submerged Servo Filling and Net Weight Dosing System

Product Description

The automatic paint filling machine is designed for high-viscosity liquid products such as latex paint, industrial coatings, resins, and chemical liquids. The system integrates submerged servo filling, high-precision net weight dosing, and automatic lid sealing technology to solve two critical challenges in paint packaging: aeration and splashing. By filling below the liquid surface and synchronizing nozzle lift with liquid level, the machine minimizes foam, improves filling accuracy, and protects product quality. It is ideal for coating manufacturers, chemical plants, and industrial liquid packaging lines requiring precision, safety, and high OEE performance.

Specifications

Applications

1. Latex paint and architectural coating filling.

2. Industrial coatings and resin liquid filling.

3. Chemical liquid products requiring net weight dosing.

4. High-viscosity liquid packaging lines for paint manufacturers.

Core Advantages

1. Submerged Servo Filling Technology
The nozzle starts filling from the bottom of the pail and rises with the liquid level, eliminating aeration and splash contamination.

2. High-Precision Net Weight Dosing
Real-time load cell feedback ensures stable dosing accuracy and reduces costly product giveaway.

3. Integrated Lid Sealing Assurance
Supports snap-on lids or screw caps with controlled sealing force to prevent leakage during transport.

4. Heavy-Duty Chemical-Grade Construction
Corrosion-resistant materials and explosion-proof options support demanding chemical production environments.

5. Rapid Tool-Less Changeover
Supports fast switching for different pail sizes and production requirements.

How to Choose

1. Choose this machine if you need accurate filling for high-viscosity paint or coatings.

2. Choose this machine if aeration and splashing control are critical.
