Piston filling systems are commonly used for viscous and semi-viscous products because they provide controlled and accurate dosing. The ideal configuration depends on product viscosity, particle content, filling volume, container type and required production speed.

Yes. Paste filling systems can be configured for sauces, jams and other products containing particles. The appropriate hopper, valve, nozzle and filling pathway should be selected according to particle size and product characteristics.

A heated hopper may be recommended for products that become too viscous or solidify at lower temperatures. Controlled heating helps maintain suitable flow and more stable filling performance.

Pneumatic piston fillers provide a simple and reliable solution for many paste applications, while servo-driven systems offer programmable control, easier volume adjustment and greater flexibility for automated production.

Yes. Many ZONESUN paste fillers can be adjusted or customized for multiple container sizes and filling volumes. Changeover requirements depend on the container, filling range and machine configuration.

Yes. ZONESUN can integrate container feeding, paste filling, cap feeding, capping or sealing, labeling, coding, conveying and end-of-line packaging into a customized automatic production line based on your product, container and required output.
