What liquids can an automatic liquid filling machine handle?▼
Automatic liquid filling machines handle water-thin liquids (water, juice, alcohol, vinegar — <100 cP), medium-viscosity liquids (sauces, syrups, shampoo, lotion — 100–10,000 cP) and moderately viscous products (honey, gel — up to ~50,000 cP with heated hopper). For very high viscosity (cream, paste — >50,000 cP), a dedicated viscous filler with gear pump or lobe pump is recommended. The filling principle — piston, peristaltic, flow meter — is selected based on viscosity, product sensitivity and required accuracy.
How fast is an automatic liquid filling machine?▼
Speed depends on the number of fill heads and fill volume. Single-head auto filler (5ml–500ml): 20–60 fills/min. 4-head inline auto filler (50ml–2,000ml): 60–150 fills/min. 8-head inline auto filler (50ml–1,000ml): 120–250 fills/min. 12–20 head rotary filler (50ml–500ml): 200–600 fills/min. For very small volumes (1ml–10ml, pharmaceutical drops), volumetric piston with servo control: 30–120 fills/min. Target speed determines the required number of heads and machine configuration.
What is the difference between piston and flow meter filling?▼
Piston filling: a servo-driven piston draws a fixed volume of liquid into a cylinder and dispenses it. Highly accurate (±0.3%–±0.5%) for thin to medium viscosity liquids. Works with most liquid types. Easy to maintain. Flow meter filling: an electromagnetic or Coriolis sensor measures the actual volume or mass passing through the fill head. Accuracy ±0.2%–±0.3% for clean, thin liquids at high speed. Not suitable for viscous or particulate-laden liquids. Piston is the default recommendation for most automatic filling applications; flow meter is used for high-speed, high-accuracy requirements with clean thin liquids.
Can automatic liquid filling machines integrate with capping and labelling?▼
Yes. HEMUfill automatic liquid filling machines are designed for full line integration: automatic unscrambler or bottle orienter at in-feed; filling station (this machine); automatic capper (screw cap, snap cap, ROPP, pump cap or trigger sprayer); sleeve or self-adhesive labeller; date coder (inkjet or laser); checkweigher; reject mechanism; and case packer or shrink wrapper at out-feed. Integration is via conveyor linking with PLC synchronisation across all line components. A single HMI can control the entire line or individual stations can operate independently.
What container formats work with automatic liquid filling machines?▼
Automatic liquid filling machines fill: round PET/HDPE/PP plastic bottles (most common); glass bottles and jars (requires gentle handling with reduced conveyor speed and soft contact guides); aluminium cans and bottles (inline filling before seaming); flat or oval bottles (requires orientation system); wide-mouth jars and tubs (sauce, pickle, cosmetic cream); and trigger sprayer and pump dispenser bottles (requires special cap holder). Changeover between container formats requires adjustment of bottle guides, fill nozzle height and conveyor width — typically 20–45 minutes.
What is the investment for an automatic liquid filling machine?▼
Automatic 4-head inline piston filler (50ml–1,000ml, 60–100 fills/min): $15,000–$35,000 USD. Automatic 8-head inline piston filler with servo drives: $35,000–$70,000 USD. Complete filling line with capper and labeller (4 heads): $50,000–$120,000 USD. Pharmaceutical-grade automatic filler with 21 CFR Part 11: $80,000–$200,000 USD.
