A modular system for blow molding a container. The system may include a first portion, a second portion, and a third portion. The first portion and second portion may each include a shell, a mold removably coupled to the shell, and a top plate. The third portion may include a base and a base mold. The molds may be 3D printed. The molds together may define a blow mold cavity. The modular system may be used at lab scale, pilot scale, or full production scale. The molds may be durable and smooth enough for full production scale. Some embodiments are directed to methods for making a modular system for blow molding a container.

The present application includes an injection molding step and a stretch blow molding step. The stretch blow molding step is configured to include: a first step in which preliminary blow air is introduced into a preform to stretch the preform in a state in which a stretching rod does not contact the bottom of the preform; a second step which is executed after the first step, and in which the preliminary blow air is introduced into the preform and the stretching rod is moved at a set speed and pressed against the bottom of the preform to stretch the preform; and a third step which is executed after the second step, and in which final blow air is introduced into the preform to stretch the preform.

A production method for blowing a container starting from a parison comprising the steps of:

i) positioning a parison inside a forming mould (2) for forming the container;
ii) deforming the parison (10) placed in the mould (2); the step of deforming the parison (10) comprising the sub-steps of: introducing a pressurised fluid into the parison (10) placed in the mould (2); sucking gas which is located inside the mould (2) and outside the parison (10) present in the mould (2).

A method for producing filled containers (16) from preforms (13). Each of the preforms is transferred to a circulating molding and filling element (14) of a molding and filling station and is shaped into the respective container in a subsequent molding and filling process in a mold under the effect of pressure from a supplied filler, wherein the mold is designed in multiple parts, including a base mold (21) and mold sides (19, 20), and each container is clamped between the base mold at the bottom and the molding and filling element at the top at least at the end of the molding and filling process. The container is separated from the respective molding and filling element and the respective mold after the molding and filling process. The mold sides are removed from each container before the molding and filling element and the base mold are separated from the container.

A blow mold unit including: a blow mold including first and second blow cavity split molds and a plurality of raised bottom molds; first and second pressure receiving members; first and second fixing plates to which the first and second blow cavity split molds and the first and second pressure receiving members are respectively fixed; a third fixing plate interposed between the first and second fixing plates and to which the raised bottom molds are fixed at a first surface thereof; a pressure receiving rod extending down from a second surface; and a placement portion fixed to at least one of the first and second fixing plates and placing the third fixing plate thereon when the first and second blow cavity split molds are closed. The pressure receiving rod includes a first engaging portion engageable with a second engaging portion in a vertical direction.

A system for forming a container includes an injection station configured to inject a liquid material into a mold to form a preform. The system also includes a forming station including an apparatus for forming a container. The apparatus includes a blow mold configured to receive the preform and inject air into the preform to form the container. The blow mold includes an inner mold surface. The apparatus also includes at least one stretching rod configured to contact the preform in the blow mold and stretch the preform. The apparatus further includes electric heating elements coupled to the blow mold and positioned adjacent the inner mold surface to heat the inner mold surface. The system further includes a removal station configured to release the container from the system.

Provided is an electrical heating mold. The electrical heating mold includes a mold casing and an electrical heating device disposed in the mold casing. The electrical heating device includes an upper annular heating resistor element group configured to perform heating around a bottleneck, a middle annular vertical-inserted columnar heating resistor element group configured to perform heating around a bottle body, and a lower annular heating resistor element group configured to perform heating around a bottle bottom. The electrical heating mold has a good heating effect, a low processing cost and a simple structure.
