FIELD: manufacturing technology.
SUBSTANCE: group of inventions relates to production method with filling of plastic containers, control method using the disclosed method and system for manufacture with filling of plastic containers. Method of manufacturing includes the following steps: a) positioning preform (1) with relation to mold assembly of two or more components (20, 21, 22), said preform generally being fabricated from a plastic and being provided with longitudinal axis (17) and having stretchable portion (13) and non-stretchable portion (11); b) stretching said preform along its longitudinal axis (17); c) injecting fluid (29) into interior volume (6) of preform (1); said fluid (29) being under such pressure as to cause preform (1) to plastically deform until achieving the desired size and shape; and d) releasing said container from mold assembly (20, 21, 22) and sealing the container. According to the method, at least a portion of stretchable portion (13) of perform (1) is at a temperature below its vitreous transition temperature (Tg) and, preferably, at ambient temperatures. Control of method of manufacture includes monitoring the position of the stretching element, volumetric flow rate and fluid pressure, stretching element force and type of deformation. Stretching element position and volume rate are adjusted. Production system with filling of plastic containers comprises mold assembly, stretching element means of injection into preform and other nodes of the system.
EFFECT: technical result achieved when using methods and systems according to inventions consists in reduction of amount of energy by reducing the value of preform heating before moulding.
