Method for recapturing and reusing heat provided in the course of fabricating a molded plastic product.

Apparatus (1) for transforming plastic preforms (10) to form plastic containers (20) with a plurality of blow moulding stations (8), wherein these blow moulding stations (8) each have a blow moulding device (14) which consists of two blow mould halves and a base mould, and wherein the blow moulding device in each case forms a cavity inside which the plastic preforms (10) can be transformed to form the plastic containers (20), and which is releasably arranged indirectly or directly on blow mould supports (16), wherein each blow moulding device has at least one temperature control device (30) with at least one electrical heating element (32) for temperature control of at least some regions of the blow moulding device (14). According to the invention the apparatus (1) has at least one electrical connection (34) which can be automatically released and/or automatically made between at least one electrical heating element (32) and the blow moulding station (8).

A device for blow molding a container from a preform. The device includes a mold base and a pedestal for supporting the mold base. An electric heating element is beneath the mold base for heating the mold base. An insulator is between the heating element and the pedestal.

A method for transferring a negative structure of a surface of an inner wall (51) of a blow molding tool (1) onto a surface of a plastic container. The method comprises the steps of heating at least one region (511) of a mold cavity (6) of a molding body (4) of the blow molding tool (1), on which the negative structure is formed, inserting a preform into the mold cavity (6), closing the blow molding tool (1), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall (51) of the mold cavity (6), cooling the region (511) by supplying a coolant through temperature control channels (54), and removing the plastic container from the mold.

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.

A forming unit (20) for forming plastic preforms into plastic bottles, wherein the forming unit comprises a blow mould (20) having a first lateral portion (4), a second lateral portion (6) and a bottom portion (2), wherein said lateral portions as well as the bottom portion (2) form a cavity (15), within which the plastic preforms (10) can be formed into the plastic bottles, wherein the bottom portion (2) can be moved relative to the lateral portions (4) in a closed condition of the blow mould, wherein the forming unit (20) comprises a drive unit in order to move the bottom portion (2) relative to the lateral portions (4, 6), wherein the drive unit preferably has a movable piston element (32) which ist movable along a predefined stroke path. According to the invention, the apparatus has a first stroke path limiting means (22, 24) that limits the stroke path of the bottom portion (2) and/or of the piston element (32) in a first direction, wherein this stroke path limiting means (22, 24) is adjustable in order to modify the stroke path.

Provided is a method for manufacturing a container 10 made of resin, the method including an injection molding step S1, a temperature adjustment step S2, and a blow molding step S3. In the temperature adjustment step S2, a preform 11 is accommodated in a cavity mold 31, an air introduction member 32 is brought into airtight contact with the preform 11, the air is supplied from a blowing port of the air introduction member 32 into the preform 11, and the air is discharged from a discharge port of the air introduction member 32 to an outside of the preform 11, so that the preform 11 is in close contact with an inner wall of the cavity mold 31 and is cooled.

An apparatus for forming plastic preforms into plastic containers with at least one forming station which forms the plastic preforms into the plastic containers by the action of a flowable medium, wherein the forming station has a blow mould which forms a cavity, within which the plastic preforms are formed into the plastic containers. The blow mould has a base part which has an inner contour which forms a base of the containers, wherein the base part has at least one channel for conducting a temperature control medium for temperature control of the base part. A course of the channel is adapted to a course of the inner contour and/or the channel has, on its inner surface facing the temperature control medium, structures and/or cross-sectional changes which influence the flow of the temperature control medium through the channel.
