Our 5L Automatic Weighing Filling Machine is a high-performance solution designed for the precision packaging of liquid materials into tin buckets and plastic containers. Utilizing advanced weighing technology, this system ensures a 0.2% accuracy rate, making it unaffected by material viscosity or temperature changes.
Whether you are filling lubricating oil, edible oils, disinfectants, or chemical coatings, this machine provides a stable, drip-free, and high-speed workflow. With its wide range of 0.5kg to 50kg, it serves as an all-in-one workstation for diverse production needs.
The system features a sophisticated Fast/Slow dual-stage feeding valve. This technology allows the machine to fill at high speed during the bulk phase and switch to a precise "drip" speed as it nears the target weight, ensuring perfect accuracy without overflow or splashing.
Petrochemicals: Lubricating oil, engine oil, and industrial grease.
Chemicals: Paints, printing inks, coatings, and disinfectants.
Food & Pharma: Edible oils, alcohol-based solutions, and liquid additives.

The system can store up to 10 different product formulas. This allows operators to switch between different liquid densities and container sizes (e.g., from a 5L tin to a 20L plastic bucket) with a single touch, minimizing downtime.
The filling head is equipped with a high-performance drip-tight device. This ensures that even high-viscosity materials like emulsion paints are poured without air bubbles or messy spills, keeping the container and the workspace clean.
The workstation is equipped with a pneumatic clamp cover and a pneumatic pressure plate device. After filling, the operator can easily seal the barrel using the auxiliary positioning device, creating a professional and leak-proof seal.
Choose between Standard Top-Filling or Submersible Lifting Filling. The submersible method is ideal for materials prone to foaming, as the nozzle lifts gradually with the liquid level to eliminate bubbles.
Manual Alignment: The operator places the barrel on the stainless steel roller platform.
One-Touch Start: Press [Start]; the dual-stage valve opens for high-speed filling.
Precision Cut-off: At the pre-set weight, the valve switches to slow mode and then shuts off completely.
Capping: Move the barrel to the gland position; the pneumatic device applies the seal.
Discharge: The filled and sealed barrel is moved to storage via the unpowered roller track.
