A resin container manufacturing method includes: forming a first pattern on a preform of a resin container; and forming a second pattern on the preform based on a position of the first pattern on the preform.

Plastic preforms are transported during their heating along a predetermined transport path and rotated with respect to their longitudinal axis during transport along a first transport path section to achieve uniform heating of the plastic preforms in the circumferential direction. The plastic preforms remain at least in sections in a predetermined first rotational position with respect to their longitudinal axis during their transport along a second transport path section so that first predetermined circumferential sections of the plastic preforms are heated differently from second predetermined circumferential portions of the plastic preforms. The plastic preforms remain at least in sections in a predetermined second rotational position with respect to their longitudinal axis during their transport along the second transport path section, the first and the second rotational position differing from one another by a predetermined differential angle.

This information management method for a resin molded product in a molding device for intermittently producing resin molded products includes: classifying the resin molded products into molded product groups for each molding cycle; acquiring an information group for each of the molded product groups; and recording the acquired information groups in association with the molded product groups.

An apparatus for blow molding plastic containers includes a blow molding carousel and is connected, at a first transfer station, to a feeding line of preforms, the first transfer station having a transfer carousel supporting a grip elements which are associated with at least one respective grip body., e Each grip element has a first arm, which is supported so that it can rotate by the transfer carousel in order to rotate on command about a substantially vertical pivoting axis, and a second arm, which extends longitudinally and can slide on command with respect to the first arm along an advancement/retraction direction which is substantially parallel to its own direction of extension. The grip body includes a coupling element which is configured to stably hold the preform.

A step of letting a preform made of resin adsorb a sterilizer, a step of sterilizing the preform by heating the preform having adsorbed the sterilizer to a temperature suitable for a blow-molding treatment to activate the sterilizer adsorbed by the preform and a step of shaping the preform into a bottle by blowing aseptic air into the preform in a mold are performed sequentially. According to the above-mentioned steps, the sterilizer does not enter a blow-molding machine.

A production device for a fuel tank, having two or more built-in components attached to an inside of a fuel tank body when the fuel tank body is formed, includes: jigs configured to have the built-in components placed thereon; and a feed robot, as a feed device, configured to feed the built-in components, along with the jigs having the built-in components placed thereon, to a position below molding dies. The feed device may feed the jig, having the built-in components placed thereon, to the position via a subsurface feed path leading to the position.

The present invention discloses a system and a method for manufacturing fittings and connections for biaxially-oriented plastic tubes in an integral way from straight preformed tubes, with the possibility of adjusting and distributing the thicknesses as well as adjusting the specific stretching in the different areas of the fittings, allowing them to be reinforced or optimized during the method itself and without causing an increase in the production time or an increase in the raw material used, such that it allows for the manufacture of fittings of different geometric shapes (curves, tapers, couplers, branches, etc.)

Provided are a handle-orienting preform feeding mechanism and orienting preform feeding method for a bottle preform with a handle. Under the combined action of the axial rotation of a plastic bottle preform and a handle positioning structure on a preform feeding tray, the handle of the plastic bottle preform with an integrated handle (especially a PET plastic bottle preform with an integrated handle) is positioned so that the plastic bottle preform with an integrated handle enters a heating machine and a bottle blowing machine of the next process according to the predetermined orientation. Accordingly, the wrong orientation of the integrated handle of the plastic bottle preform is avoided so that a mechanical arm can grasp the plastic bottle preform correctly and place the plastic bottle preform at the correct position of a bottle blowing mold. Thus the plastic bottle preform can be blown successfully.

An apparatus for blow molding plastic containers includes a blow molding carousel and is connected, at a first transfer station, to a feeding line of preforms, the first transfer station having a transfer carousel supporting grip elements which are associated with at least one respective grip body. Each grip element has a first arm, which is supported so that it can rotate by the transfer carousel in order to rotate on command about a substantially vertical pivoting axis, and a second arm, which extends longitudinally and can slide on command with respect to the first arm along an advancement/retraction direction which is substantially parallel to its own direction of extension. The grip body includes a coupling element which is configured to stably hold the preform.
