Oral Liquid Filling Machine

Packaging oral liquid products requires more than accurate dosing. Bottle positioning, hygienic filling, reliable sealing and smooth product transfer all influence production efficiency and product consistency.
The Oral Liquid Filling Machine developed by Wanying is engineered to integrate seamlessly into automated packaging systems. Whether used as an independent unit or connected with bottle unscramblers, capping equipment, labeling machines and cartoning systems, it helps manufacturers build an efficient workflow with fewer manual operations.
With years of experience in filling equipment development, Wanying provides customized machine layouts based on bottle specifications, production targets and workshop conditions instead of relying on fixed equipment configurations.

Packaging & Delivery

Wanying follows a standardized packaging and logistics process to ensure every Oral Liquid Filling Machine arrives safely and ready for installation.

Packaging Process:

· Protective film wrapping for dust and moisture prevention

· Reinforced wooden case for structural protection

· Internal shock-absorbing materials to prevent vibration damage

· Component labeling for quick on-site installation

Delivery Assurance:

· Pre-shipment inspection and full functional testing

· Equipment operation verification before packing

· Secure loading process with reinforced fastening

· Logistics tracking support until arrival at destination

This ensures that the equipment maintains factory condition throughout transportation and is ready for immediate setup upon arrival.

Frequently Asked Questions

Q1: Can the Oral Liquid Filling Machine handle different bottle sizes?

Yes. Filling parameters and bottle handling components can be adjusted or customized to accommodate various bottle dimensions (18–55 mm diameter). Changeover between sizes takes less than 20 minutes with preset recipes stored in the PLC.

Q2: Is the equipment suitable for continuous production?

Yes. It is designed for long production runs with stable filling accuracy and reliable bottle conveying. Our 8–12 hour continuous run testing before shipment verifies long-term stability.

Q3: What types of pumps does the machine use, and how do I choose the right one?

The machine supports volumetric piston pumps (for most liquids), ceramic pumps (for abrasive or acidic liquids), and peristaltic pumps (for sterile/biological products). Our engineering team will recommend the optimal pump type based on your product characteristics, viscosity, and specific volume requirements.

Q4: What does ±0.3% filling accuracy mean in practice, and why is it important?

For a 10 ml fill, ±0.3% accuracy means each bottle contains between 9.97–10.03 ml. This level of precision ensures regulatory compliance, consistent product quality, and reduces product give-away—saving up to 2–5% on high-value liquids.

Q5: Does Wanying provide customized solutions?

Yes. Engineers recommend machine configurations based on production capacity, bottle specifications, product viscosity, and packaging process requirements. Customized layouts, pump selections, and additional modules can be configured to meet your specific needs.
