| Model | Best For | Viscosity Range | Nozzles | |
|---|---|---|---|---|
| VEVOR Paste Liquid Filling Machine (30-15000g) | Small-batch producers needing precision | Low to medium | 6 | Automatic |
| [2026 New Version] Moonshan 2-300g | Perfume, essential oil, light liquids | Low | 1 | Automatic/Weigh-based |
| Moonshan 4-Nozzle Automatic Liquid Filling Machine Line | Small workshop with multiple bottles | Low to medium | 4 | Automatic |
| Moonshan Viscous Liquid Filling Machine 2-IN-1 | Honey, syrup, viscous sauces | Medium to high | 2 | Automatic |

VEVOR Paste Liquid Filling Machine 30-15000g
Best for small-batch production where precise dosing matters. This model uses a digital control system with automatic tare deduction and a target quantity stop, making it ideal for formulations where accuracy is critical. It handles low to medium-viscosity liquids like oils, detergents, and shampoos with a high-flow diaphragm pump reaching 17 L/min. It includes six nozzle sizes for varied container diameters, aiding quick changeovers between bottle formats. A limitation is that thicker liquids flow more slowly, so plan for slower fill times with viscous products.
[2026 New Version] Moonshan 2-300g Bottle Filler
Best for compact operations needing precise weight-based filling for small bottles. This model upgrades to a digital control panel that tare-calibrates automatically, then fills with a controlled pace as the target is approached. It uses a hygienic peristaltic pump to minimize contamination since liquid contacts only the silicone tubing. It supports three modes: weight-based, time-based, and price-based, delivering straightforward operation without manual speed calculations. Note: performance is strongest with liquids that flow consistently; very thick formulations may require slower fills or alternative models.
Moonshan 4-Nozzle Automatic Liquid Filling Machine Line
Best for small workshops needing multi-nozzle parallel fills. The desktop version integrates filling, belt conveyor, and infrared sensing for automated operation at a compact footprint. Independent control allows customizing fill speeds per pump, making it suitable for bottles of various sizes in one run. It works well for juices, wines, and light detergents, provided bottle diameters stay within 20-90 mm and heights between 40-400 mm. Limitation: cylindrical bottle shapes are preferred; confirm compatibility with unusual shapes before purchasing.
Moonshan Viscous Liquid Filling Machine 2-IN-1
Best for thick liquids such as honey, syrups, and sauces. This 2-IN-1 system combines a weighing-based and a time-based fill mode with a stainless steel gear pump capable of handling high-viscosity products. It includes an anti-drip nozzle and a three-stage fill speed to improve accuracy—up to 1 gram precision in some setups. Choose this if your product is viscous and you require accurate batch dosing. Caution: very thick pastes may require preheating or heating to improve flow in some configurations.
VEVOR Liquid Filling Machine 50-5000 g
Best for general-purpose filling of low to medium viscosity liquids like oil, detergent, and light sauces. Features a robust 120W gear pump with a 2 L/min potential flow for quicker production runs, and a digital controller that handles tare deduction and target quantity stopping. It supports a wide range of fill quantities from 50 g to 5000 g. Note: thicker products may reduce flow rate; ensure the liquid has good flowability for optimal results.
VEVOR Manual Paste Liquid Filling Machine
Best for budget-conscious users who still need reliable manual control for small containers. This machine uses a reinforced handle and a simple, calibrated scale for precise 5-100 ml fills. It includes two nozzle options (4 mm and 8 mm) and a height-adjustable shelf to accommodate various bottle heights. Choose this if you prioritize simplicity and cost efficiency and you are filling consistently sized, slender containers. Limitation: manual filling can be slower and requires manual operation for each fill.
Buying Guide
What container sizes and bottle shapes will you fill?
Choose a model with nozzle counts and bottle diameter compatibility that match your typical containers. If you have multiple bottle sizes, look for adjustable components, independent pump control, or multiple nozzle options to minimize changeover time.
What viscosity range will you handle?
For thin liquids, most automatic lines with 4-nozzle or single-nozzle systems offer fast fills. For thicker liquids like detergents with higher viscosity, favor models with gear pumps, double-acting or peristaltic pumps, and anti-drip features to maintain accuracy and reduce waste.
How important is automation and accuracy?
Digital control with tare deduction provides the most consistent results and reduces operator error. Weigh-based filling is ideal when exact quantities are critical. If you operate on a tight budget and manual labor is acceptable, a manual model can still meet small output needs.
What are your space and workflow constraints?
Desktop or small-line configurations are suitable for compact workspaces. Integrated conveyors and sensors minimize handling and improve throughput, but require a stable electrical setup and proper maintenance to avoid jams.
Maintenance and cleanliness considerations
Peristaltic pumps reduce contamination risk since the liquid contacts only tubing. Food-grade materials and easy-to-clean designs are worth prioritizing when dealing with consumables or sensitive formulations. Check for dishwasher-safe components and accessible hose/tube connections for quick cleaning.
Operational safety and ergonomics
Choose models with safe, ergonomic handling—reliable handles, clear calibration marks, and straightforward start/stop controls. For manual lines, pedal or handheld controls can free operator hands for bottle handling and alignment.
FAQ
- What is the best filling machine for viscous detergents? A viscous-focused model with a gear pump and anti-drip nozzle is preferred, such as Moonshan Viscous Liquid Filling Machine, which is designed for thicker liquids and provides precise control.
- Can I fill multiple bottle sizes with one machine? Yes, many machines offer adjustable nozzles, independent pump control, and adjustable shelf height to accommodate different bottles in one run.
- Is a digital control panel necessary for accuracy? Digital control with tare deduction and automatic stopping yields more consistent results and reduces human error compared to purely manual filling.
- Are manual fillers sufficient for small-scale production? For very small operations or hobby-scale projects, a manual filler provides cost-effective, reliable operation with minimal setup.
- What maintenance should I plan for an automatic filler? Regularly inspect hoses and seals, clean the nozzle after each batch, and verify calibration to prevent drift in fill volumes.
- Do these machines require special liquids? Most are designed for standard detergents, oils, and light sauces; ensure the chosen model supports your specific formulation and viscosity.
