An injection molding system includes: a first extruding member that extrudes a first molded article from a mold; a robot that transfers the first molded article extruded from the mold to an assembling position in relation to a second molded article in the mold; a second extruding member that extrudes the second molded article from the mold towards the first molded article retained at the assembling position by way of the robot, and assembles the second molded article to the first molded article; and a load detection unit that detects load applied to the second extruding member, in which defect discrimination of the first molded article, the second molded article, or an assembled state of the first molded article and the second molded article is performed, based on load detected by the load detection unit when the second molded article is assembled to the first molded article.

The invention relates to a method for checking pipette tips comprising the following steps: a) providing pipette tips in a first carrier; b) receiving pipette tips from the first carrier via a holder device; c) capturing first image data using a first image-capturing device, which has an optical axis parallel to the longitudinal axis of the pipette tips and directed towards the respective outlet opening of the pipette tips; d) capturing second image data using a second image-capturing device, which has an optical axis transverse to the longitudinal axis of the pipette tips and directed towards the sub-segments of the pipette tip casing surfaces facing the second image-capturing device; e) determining whether the image data lies within predefined acceptability limits; f) discarding the pipette tips, for which the image data falls outside the acceptability limits, in a waste container; g) transferring the pipette tips, for which the image data lies within the acceptability limits, into a second carrier; wherein the second image data of multiple pipette tips is simultaneously captured in step d).

A robot system includes an image pickup apparatus that picks up images of a plurality of kinds of articles conveyed by a conveyor; an article controlling portion that controls time and a position of each of the plurality of kinds of articles being supplied onto the conveyor, to limit kinds of articles to be image-picked-up by the image pickup apparatus in advance; a detecting portion that detects the plurality of kinds of articles from among images picked up by the image pickup apparatus, on the basis of the kinds of articles limited in advance by the article controlling portion; and a robot that is configured to take out the plurality of kinds of articles detected by the detecting portion from the conveyor.

It is proposed to carry out an optical inspection of preforms (7) by means of at least one camera device (2, 3, 13), in such a way that the preforms (7) are in a relative position to each other that is unchanged in comparison with the injection molding operation.

A method for manufacturing a molded part while changing between multiple molds including a first ejecting step of opening a first mold and ejecting the molded part from the first mold, a checking step of checking the ejected molded part to determine if the molded part is acceptable, a first injecting step of closing the first mold and performing injection into the first mold, a second ejecting step of, where the ejected molded part is determined to be acceptable, changing the first mold to a second mold and ejecting the molded part from the second mold after the first injecting step, and a third ejecting step of, in a case where the molded part ejected in the first ejecting step is determined to be non-acceptable, not changing the first mold to the second mold and ejecting the molded part from the first mold.

A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.

An apparatus for forming a first component making up at least a part of a housing on a trimmer head and a method of using the apparatus. The housing has a rotary axis and is configured to support at least one radially projecting cutting component. The first component has a central axis. A forming unit defines at least one cavity within which a moldable material is confined to produce at least a part of a wall on the first component that extends around the rotary axis. The forming unit is configured to allow selective controlling of a quantity of a moldable material introduced into a first discrete subvolume at a first location in the one cavity to thereby allow selective controlling of a mass of a portion of the at least part of the wall formed by the moldable material in the one cavity at the first location to facilitate dynamic balancing of the housing, within which the first component is incorporated, with respect to the rotary axis.

An apparatus for the manufacture and unloading of preforms for the manufacture of plastic containers includes a device for the injection molding of preforms and a device for the cooling and extraction of the preforms from the molding device, and further includes a device for the selective extraction of a predetermined subset of preforms supported by the unloading plate in an orderly manner along at least one pickup direction. The apparatus also includes a component for the orderly transfer of the predetermined subset of preforms to a control and inspection device adapted to perform at least one control on the predetermined subset of preforms.

The invention relates to a packaging method and to an associated packaging device (1) for packaging injection-molded plastic parts (2), which are pipette tips or medical reaction vessels, the injection-molded plastic parts (2) being arranged in cavity-pure subgroups (6) and then subjected to lateral inspection sub-subgroup (10) per sub-subgroup (10).

An attachment for a washing or rinsing agent bottle. The attachment is made from a main component and at least one auxiliary component in a multicomponent injection casting method, wherein a seal element is molded using the auxiliary component. The main component or the auxiliary component has a marker which causes a contrast between the auxiliary component and the main component under UV light or IR light. The invention also relates to a method for producing such an attachment.
