A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.

An injection molding tool for producing a molded part and a corresponding method are disclosed. The injection mold tool comprises a first tool mold half and a second tool mold half, which together with a first slider and at least one second slider define a free space for the molded part to be produced. A lever which is pretensioned with an elastic element is assigned to an end switch such that a movable and free end of the lever cooperates with the end switch due to a movement of the first slider.

A fan includes an inlet part disposed to form a fan inlet, a base disposed to form, together with the inlet part, a fan outlet, and a blade. The blade extends from the base to the inlet part, and includes a first guide surface having an inclination toward an outside of the fan in a radial direction of the fan which changes in a direction from the inlet part toward the base, and a second guide surface having an inclination toward the outside of the fan in the radial direction which changes in a direction from the base toward the inlet part.

A preform molding system is disclosed that includes a cavity half that is mountable to a stationary platen of an injection molding machine and a core half that is mountable to a moving platen of the injection molding machine. The preform molding system includes a mold stack assembly having a cavity portion and a core portion. The cavity portion is coupled to the cavity half and includes a cavity insert, and the core portion is coupled to the core half and includes a core insert, a pair of neck rings, and a stripper ring. The core insert has an undercut that defines an annular protrusion on an internal surface of a preform that is created in the mold stack assembly. The preform molding system is configured to permit in sequence, retraction of the pair of neck rings away from the core insert and ejection of the preform from the core insert via the stripper ring.

A method for moulding an elongate articulated bending section body (4) for a medical device including a number of segments (7) interconnected via a number of hinge members (8). The method includes the use of a mould having a first number of sub-cavities where each of the sub-cavities has at least one external fluid inlet through which a liquified plastic material is injected into the mould. The sub-cavities are so distributed that each sub-cavity is separated from another sub-cavity by an odd number of sub-cavities without an external fluid inlet.

The invention relates to a cold runner block in a vertically operating injection molding machine for processing elastomer materials with an upper fixed molding platen and a molding platen arranged thereunder which is movable relative to the fixed molding platen, between which a molding tool having a plurality of mold cavities is arranged and wherein the cold runner block is arranged between the fixed molding platen and the molding tool, the cold runner block containing a distribution plate having the cold runners and containing a nozzle plate with nozzles each assigned to one of the plurality of mold cavities, which is characterized in that the distribution plate formed from a plurality of distribution strips (10-40) is arranged on a retaining plate (2), which can be fastened to the fixed, feed-side molding platen in such a way that each distribution strip (10-40) is connected by means of two bolts (3) to the retaining plate (2) in that the head (5) of each bolt (3) facing away from the distribution strip (10-40) forms a retaining element which is T-shaped in section, the retaining element being displaceably guided in the direction transverse to the distribution strip's longitudinal axis in guide rails (50) which are formed in the retaining plate (2) and are designed in section to complement the bolt head (5).

In an aspect, a mold stack may comprise two adjacent components, one at least partially defining a vent adjustable between a molding configuration and a cleaning configuration. A junction of the components may be adjustable between a molding configuration, wherein mating faces contact one another to define a parting line, and a cleaning configuration, wherein mating faces are separated to create a molding cavity extension therebetween and an auxiliary melt barrier prevents uncontrolled flashing from the extension.

A main body portion is disposed at a regular position by inserting a protrusion into an engaging portion formed in a leg portion of the main body portion in accordance with a forward movement of a sliding mold including the protrusion. Then, an injection molding mold is completely closed to cause at least a part of a mold surface of the sliding mold to come into contact with the main body portion.
