A process for the manufacturing and filling of plastic containers, the process comprising the steps of: positioning a preform with relation to a mold assembly of two or more components, the preform generally being fabricated from a plastic and being provided with a longitudinal axis and presenting a stretchable portion and a non-stretchable portion; stretching the preform along its longitudinal axis; injecting a fluid into the interior volume of the preform, the fluid being under such pressure as to cause the preform to plastically deform until achieving the desired size and shape; and releasing the container from the mold assembly and sealing the container, and in which at least a portion of the stretchable portion of the perform is at a temperature below its vitreous transition temperature (Tg) and, preferably, at ambient temperatures.

RESIN CONTAINER MANUFACTURING DEVICE AND MANUFACTURING METHOD

There is provided a resin container manufacturing apparatus configured to stretch a preform disposed in a stretch blow molding mold by a stretching rod and stretch the preform by introducing blow air into the preform so as to form a resin container. The resin container manufacturing apparatus includes detection means for detecting an actual position of the stretching rod inserted into the preform, and supply control means for controlling a supply state of the blow air based on a detection result of the detection means.

LIQUID BLOW MOLDING APPARATUS
20180354185 · 2018-12-13 ·

A liquid blow molding device for liquid blow molding a resin preform into a container having a predetermined shape. The liquid blow molding device includes a mold in which the preform is disposed; a stretch rod that axially stretches the preform disposed in the mold (; and a pressurized liquid supply that supplies a pressurized liquid to the preform. The liquid blow molding device operates such that the amount of the liquid supplied from the pressurized liquid supply to the inside of the preform before completing the stretching of the preform by the stretch rod (22) is 50% or less of the amount of the liquid to be filled in the container after the completion of the liquid blow molding.
