Piston Filling Machine — Manufacturer & Supplier in China
Piston filling machines for viscous products: sauce, paste, cream, honey, gel. +0.5-1% accuracy. 1-12 nozzles. Chinese factory-direct.
A piston filling machine uses a reciprocating piston inside a cylinder to draw a precise volume and discharge it into the container. It is the most accurate and versatile filling principle for viscous products from 500 to 500,000 cP.
Piston fillers handle products that gravity cannot move: sauces, pastes, creams, gels, honey, and products with soft particles. Accuracy of +0.5-1% of fill volume is standard.

FAQ
What products work best with piston filling?
Viscous products above 500 cP: sauces, pastes, creams, gels, honey, syrup, and products with soft particles. Products with hard particles may need a wider valve or hopper agitator.
How does piston filling accuracy compare?
Piston: +0.5-1%. Gear pump: +0.2-0.5%. Gravity: +1-5%. Overflow: +1-3% (volume) but +1mm (level). Net-weigh: +0.1-0.5% (highest accuracy, slowest).
