Disclosed are a process to mold and fill plastic containers and form-filling machine. The invention relates to a process for molding and filling plastic containers and a form-filling machine to implement the process. The process is used for molding and filling of plastic containers. Preforms in hollow molds are reshaped into the containers by at least partial addition of an incompressible molding fluid under the impact of overpressure. Due to the condition that the containers are also filled with a product in the hollow molds, in which the molding fluid is replaced by the product or partially replaced by at least one component of the product, the temporal or technological effort for the production of the containers and for bottling of the product can be reduced.
