Powder filling machines are mainly used for filling powder and granular materials with poor flowability, while liquid filling machines are suitable for water-like products with low concentration and fewer impurities. The two types differ significantly in applicable materials and filling methods. For different materials such as liquids, oils, pastes, granular slurries, and powders, corresponding filling equipment should be selected to meet the filling requirements of containers in various specifications.
Structurally, powder filling machines typically use screw feeding, vibrating hoppers, or vacuum filling to maintain stable powder flow, while liquid filling machines often use piston, peristaltic pump, or gravity filling principles. Because of the different material characteristics, the two types of equipment also have different design requirements for metering mechanisms, filling heads, seals, and container positioning components.
For non-standard structural parts in the above filling equipment, such as powder screw shafts, filling nozzles, sealing flanges, adjustment bases, and liquid filling valve bodies, Hansheng Automation provides custom machining services based on customer drawings, supporting material selection and tolerance control to meet the filling needs of different materials and container specifications. When changing filling materials, the equipment usually does not require a large number of additional spare parts; only some structural adjustments or parameter changes are needed to complete the switchover.
