Automatic Liquid Filling Machine

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.

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.

Piston filling: a servo-driven piston draws a fixed volume of liquid into a cylinder and dispenses it. Highly accurate (by RFQ) 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 by RFQ 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.

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.

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.
