A process for making an object from plastic material includes the following operations: moulding at least one insert, injecting a first plastic material into a first moulding cast, such first cast being configured so that the at least one insert includes a base from which exposure reliefs extend, intended to be visible when the object made of plastic material is finished, between the exposure reliefs passage channels being defined for a second plastic material in a subsequent overmoulding operation; positioning the insert in a second moulding cast, so that the insert is positioned with the base pressed against a first surface of a first half-mould of the second cast, and with the exposure reliefs pressed against an opposite second surface of a second half-mould; overmoulding a second plastic material on a part of the insert, injecting the second plastic material into the second cast, so that the second plastic material injected fills the second cast passing through the passage channels defined between the exposure reliefs of the insert, covering the base and being interposed between the exposure reliefs.

Disclosed are injection molds, injected molded articles, and methods for using the same. The injected molds include a mold cavity and an injection molding conduit having a first end, a second end defining an outlet in fluid communication with the mold cavity, a first interior transverse dimension that is perpendicular to a longitudinal axis of the injection molding conduit, a second interior transverse dimension that is perpendicular to the longitudinal axis and to the first interior transverse dimension, and at the second end, the second interior transverse dimension is at least three times larger than the first interior transverse dimension, and the second interior transverse dimension of the injection molding conduit is substantially aligned with a thickness of a portion of the mold cavity that is adjacent to the outlet of the injection molding conduit.

This invention relates to a handling device for the removal of plastic injection-molded parts, designed as pipette tips, medical reaction vessels or contact-lens molds, from an injection mold tool (11), having a removal gripper having a plurality of receiving positions (1-32; 104, 105) for receiving one injection-molded part from each of the cavities in each instance.

In an injection molding system, a molded part transport apparatus and a worker share an area to perform cooperative work. When a molded part check mode is valid, conforming product identification inspection of a molded part is performed in an area where the worker works, and molded part sorting means sorts the molded part on the basis of a result of the inspection. As a result, the conforming product identification inspection of the molded part can be performed and the molded part can be sorted with the safety of the worker is maintained.

An installation and method for producing coated plastic components, having a first plastic manufacturing device and at least a second plastic manufacturing device for producing plastic components and a coating device for the surface coating of plastic components. The coating device has a first coating line which is associated with the first plastic manufacturing device and at least a second coating line which is associated with the first and/or second plastic manufacturing device. The first and/or second plastic manufacturing device is preferably an injection molding device or an additive manufacturing device.

An injection molding system includes a first unit in which an injection molding machine is disposed and an option unit. The injection molding machine is configured to be attachable with a stationary die and a movable die that moves with respect to the stationary die. The option unit includes at least one of a second unit in which a robot that moves a molded article molded by the injection molding machine is disposed and a third unit in which at least one of a material dryer that dries a material supplied to the injection molding machine and a material supply section that supplies the material to the injection molding machine is disposed. The first unit is configured to be detachably attachable with the option unit.

Method for transferring injection moldings, in particular pipette tips (P), out of an injection-molding machine into packaging containers (V1 to V4), comprising the following steps: removing the injection moldings (P) in an annular arrangement from a mold (W) of the injection-molding machine by way of a removable gripper (100), converting the annular arrangement into a row arrangement of the injection moldings (P) in a transfer station (101), positioning the injection moldings (P) in the transfer station (101) in a manner corresponding to the positioning in a workpiece carrier (102), and transferring the injection moldings (P) into the workpiece carrier (102) by way of the transfer station (101), whereupon the injection moldings (P) are inserted into the packaging containers (V1 to V4) from the workpiece carrier (102).

An injection molding system includes a plurality of inspection apparatuses for inspecting molded article quality, a unit that transports a molded article molded by an injection molding machine, a molded article containment unit that is provided for each of types of post-treatment operations needed for the molded article, a transport destination designation unit that selects and designates the molded article containment unit to contain the molded article on the basis of a combination of inspection results from the plurality of inspection apparatuses, and a molded article sorting and transport unit that sorts and transports the molded article into the molded article containment unit designated by the transport destination designation unit.

The present invention relates to a conveyance device with which a subject to be molded can be positioned relative to a forming die. This conveyance device conveys a subject to be molded to one die from among forming dies to which a resin material is supplied from a resin injection part and comprises a retaining unit which retains and delivers the subject to be molded to the one die, a first movement mechanism which moves the subject to be molded having been delivered to the one die in a first direction toward the resin injection part, and a second movement mechanism which moves the subject to be molded having been delivered to the one die in a second direction differing from the first direction.

A handling device (1) for tubular or elongate bowl-shaped workpieces such as pipette tips (4) or cups, said workpieces preferably being transported or being able to be transported on a workpiece carrier (T) during the production of said workpieces until packaging, the workpiece carrier (T) having receiving places (5) for the workpieces, which receiving places are arranged in a grid relative to each other, preferably with the stipulation that faulty workpieces located on the workpiece carrier (T) can be detected, and preferably with the stipulation that a removal station (25) is provided, by means of which the faulty workpieces can be removed from the receiving places (5) of a workpiece carrier (T), receiving places (5) thus being freed up, freed-up receiving places (5) of the workpiece carrier (T) being able to be loaded with faultless workpieces by means of the handling device, the handling device comprising a refill magazine (2), which has magazine places (3) arranged next to each other, each magazine place having a holding element (7) that can be moved up and down and that is used to secure and to receive and release a faultless workpiece, with the additional stipulation that each magazine place (3) comprises a guide tube (6), in which the up and down movement of the holding element (7) occurs, the holding element (7) being able to be moved, together with a secured workpiece, into the guide tube (6), and that an acceleration apparatus (V) is provided, by means of which the workpiece can be accelerated out of the guide tube (6) and can be moved to a receiving place (5) of the workpiece carrier (T).
