A8 Automatic 8-Head Liquid Filling Machine

A8 Automatic 8-Head Liquid Filling Machine

Product & Models: A8 Series (A8-100 / A8-300 / A8-500 / A8-1000 / A8-2500 / A8-5000)

Core Abstract

The A8 Series is a fully automatic 8-head piston liquid filling machine from Wenzhou T&D Packaging Machinery Factory — the top-output model of the A4/A6/A8 liquid filling family. Engineered for food (drinking water, edible oil, juice, milk, sauce), daily chemical (shampoo, dishwashing liquid, hand soap, liquid detergent), and cosmetic & chemical producers filling liquid materials, it fills 8 bottles per cycle in synchronization, with an output of 1200–1800 bottles/h. Six models cover filling ranges from 10–100 ml to 500–5000 ml with accuracy within ±1%. A Taiwan-brand PLC with touchscreen, Taiwan Airtac pneumatic components, and German SICK photoelectric sensors ensure stability and precision through long-term, high-frequency operation. The conveyor auto-feeds bottles with photoelectric counting and positioning, and no-bottle-no-fill logic; bottom cut-off positive shutoff nozzles guarantee zero dripping and no contamination. Liquid-contact parts are made of food-grade 304 stainless steel (304/316 or anti-corrosion rubber sealing optional), GMP compliant, CE certified, delivered within 30 days, with a 1-year warranty.

IV. Sales Recommendations & FAQ

Sales Recommendations

  • Model Recommendation: Suggest the model based on the upper limit of the customer's bottle capacity — e.g., for bottles from 200 ml to 800 ml, recommend the A8-1000 for the best accuracy coverage.
  • A4 / A6 / A8 Positioning: For customers whose 6-head output still falls short of demand, or who run medium- to large-scale production, recommend the A8 — 8 synchronized heads maximize throughput per cycle while keeping the same compact footprint and control system.
  • Bundle Guidance: Can be combined with a capping machine and labeling machine to form a fully automatic production line, increasing the average order value.

FAQ

  1. What is the difference between the A8 and the A4/A6 Series?
    All three share the same Taiwan-brand PLC control, Airtac pneumatic system, and ±1% filling accuracy. The A8 has 8 filling heads (A4: 4, A6: 6), filling 8 bottles per cycle at 1200–1800 bottles/h — the highest throughput of the family, ideal for medium- and large-scale production.
  2. Does the machine support corrosive liquids?
    Yes. For corrosive materials, anti-corrosion rubber sealing rings can be used in place of the standard food-grade silicone O-rings, and full 316 stainless steel contact parts are optional.
  3. Is installation and training difficult?
    No. The machine is fully debugged before shipping. Detailed video tutorials and one-on-one online engineer guidance are provided.
  4. Can heating and mixing functions be added?
    Yes. For high-viscosity or easily solidifying materials, custom heating and stirring hoppers are available.

VI. Workflow

Step-by-Step Workflow

  1. Bottle Feeding: Empty bottles are automatically conveyed into the machine.
  2. Counting & Positioning: The inlet SICK photoelectric sensor counts bottles; once 8 bottles are reached, the bottle stop cylinder extends for precise positioning.
  3. Filling: The filling heads descend and the pistons push material, achieving synchronized 8-head high-precision filling.
  4. Anti-Drip Handling: When filling ends, the bottom cut-off positive shutoff valve closes and the heads rise, ensuring zero dripping.
  5. Bottle Discharge: The stop cylinder retracts and the filled bottles move on to the capping/labeling process.
