Piston Filler machines are extremely flexible linear filling machines for automated dosing of products mixed with pieces, low viscosity liquids and high viscosity liquids, such as creams or pastes. The structure of the machine is built entirely in AISI 304L stainless steel, while the parts in contact with the product are in AISI 316L stainless steel. The polymers used are strictly compliant with chemical and thermal exposures, compatible with the reagents used for sanitization.
