The Automatic Economic Piston Filling Machine is an affordable yet highly efficient solution for small to medium-scale production lines, designed to handle thin to high-viscosity liquids such as detergent, liquid soap, shampoos, lotions, and so on. Built with 304/316 stainless steel and food-grade contact parts, it guarantees hygiene, durability, and compliance with international safety standards (CE, RoHS).
Equipped with PLC control and a user-friendly touch screen, operators can easily adjust filling volumes (100–5000ml), nozzle positions, and production speed. The machine supports 2–4 nozzles and features anti-drip, anti-foam, and “no bottle, no fill” safety systems, ensuring high accuracy (±0.5%) and minimal waste. Optional diving nozzles and specialized seals allow it to handle foaming, corrosive, or hazardous liquids efficiently.
Powered by a servo motor or pneumatic drive, the machine offers stable, reliable performance, with automated alerts for operational issues. Its horizontal piston design simplifies cleaning and maintenance, while standard drip trays and precise bottle alignment enhance cleanliness and productivity. Ideal for the food, cosmetic, pharmaceutical, and personal care industries, this machine delivers cost-effective automation without compromising quality.
