Manufacturing a molded part using one injection molding machine while changing between multiple molds includes performing, at a molding operation position in the injection molding machine, clamping, injection, and dwelling of a mold, conveying the mold from the molding operation position and performing a process of cooling the mold at a position different from the molding operation position, conveying the mold to the molding operation position, opening the mold, and ejecting a molded part from the mold, wherein, before performing the first step for a first mold, a molded part previously ejected from a second mold is placed into the first mold that has been opened.

A melting heater configured to melt joining end surfaces of a pair of semi-molded products in a case where the joining end surfaces are melted and joined to manufacture a molded product, the melting heater including: two glass plates arranged in parallel to each other; and a plurality of element heaters arranged in a unit having a flat plate shape as a whole between the two glass plates, in which the glass plate is subjected to surface processing for controlling infrared rays emitted from the plurality of element heaters.

A method of forming a tensioner arm bracket, chain guide, snubber or tensioner arm with two shot injection molding. The tensioner arm bracket, chain guide, snubber or tensioner arm each having a body and a chain sliding face. The body of the tensioner arm bracket, chain guide, snubber or tensioner arm bracket is formed of by a first shot of thermoplastic polymer or thermosetting resin and the chain sliding face is formed by a second shot of thermoset elastomer which is overmoulded onto the body. The body of the component is made of either a thermoplastic or thermosetting resin is fixed to its chain sliding face either by one or more of an anchor point generated by undercuts in the body and/or chemical bonds between the dissimilar materials.

A system and method for molding, forming, and annealing an article of manufacture using a series of molds are disclosed. Such systems and methods may melt degradable thermoplastic materials that are then injected into a first mold to form an article of manufacture. This article may then be moved to a second mold where the formed article is annealed. The second mold may be heated based on operation of a heating element that heats the annealing mold. This annealing process may condition materials in the formed article to enhance properties of the article. For example, annealing may improve thermal resistance of the article. Systems of the present disclosure may employ two molds, one mold that forms articles and a second mold that anneals articles to facilitate a continuous production beverage pods using environmentally friendly materials.

Composite fabrication system and associated methods. In one embodiment, a composite fabrication system comprises a molding tool that includes a forming surface at least partially disposed within a constrained space, and a foamable material that expands inside of the constrained space to form an expanded material that presses a layup of one or more composite layers against the molding tool. The composite fabrication system further comprises a curing device configured to cure the layup to form a composite part, and a cutting wire embedded in the constrained space that is heated and configured to cut the expanded material into pieces that are removable from the constrained space.

A temperature adjustment device and a temperature adjustment method for a preform in a blow molding device with which it is possible to reduce a molding cycle time is provided. A temperature adjustment device for a preform in which a hollow rod member is inserted into an injection-molded, bottomed preform retained by a retention member, and a first air circulation path is formed between the preform and the hollow rod member to adjust the temperature of the preform. The temperature adjustment device is characterized in that a flow path adjustment member is fitted and attached to the outer periphery of the hollow rod member, whereby the cross-sectional area of the first air circulation path is partially adjusted and changed.

A blow molding device is provided in which a preform is injection-molded. The injection-molded preform is temperature-controlled by a temperature adjusting unit, and the temperature-adjusted preform is blow-molded, wherein the temperature adjusting unit has a multistage structure in which an uppermost stage has the highest temperature structure, and the mold surface temperatures of lower stages and other than the uppermost stage are set to be 10° C. or more lower than the glass transition temperature of the preform.

In a manufacturing apparatus for manufacturing a resin container which includes an injection molding part configured to injection-mold a preform, a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part, and a blow molding part configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part, the preform is carried into the temperature adjustment part before an outer surface temperature of the preform molded in the injection molding part becomes higher than an inner surface temperature of the preform molded in the injection molding part, and the preform is cooled to be lowered within a range equal to or higher than 10° C. and equal to or lower than 50° C. in the temperature adjustment part.

Composite fabrication system and associated methods. In one embodiment, a composite fabrication system comprises a molding tool that includes a forming surface at least partially disposed within a constrained space, and a foamable material that expands inside of the constrained space to form an expanded material that presses a layup of one or more composite layers against the molding tool. The composite fabrication system further comprises a curing device configured to cure the layup to form a composite part, and a cutting wire embedded in the constrained space that is heated and configured to cut the expanded material into pieces that are removable from the constrained space.

A cap (1) for a container comprises: a body (2), configured to be coupled and uncoupled relative to the neck of the container and including an internally threaded side wall (21), which extends around a longitudinal axis (A), and a transverse wall (22); a tamper evident ring (3), including a retaining element (31), configured to engage a locking member on the neck of the container, and a joining portion (32), where the tamper evident ring (3) is joined to the cap body (2), the joining portion (32) being configured to be torn along a perimeter surrounding the longitudinal axis (A) in response to a movement of the body (2) away from the tamper evident ring (3), wherein the cap (1) comprises a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40).
