The present invention involves a fabrication of plastic-tube-screen-fill (PTSF) injection mold fabricating PTSFs using molten plastics injection molding machine. The PTSFs replace PVC-film-fills currently using in water evaporative cooling towers. The PTSFs have a higher water cooling efficiency compared to the efficiency of the PVC-film-fills and therefore the PTSFs reduce the operation and construction expenses of the cooling tower, and also the PTSFs reduce the production of plastic wastes due to the utilizing of high cooling efficient media in the cooling towers. In order to commercialize the PTSFs, a manufacturing tool of the PTSFs to fabricate a low-cost plastic-tube-screen-fill is needed. To achieve this end, the PTSF injection mold is invented by comprising four partial-molds, which is operated in three dimensional disassembling and reassembling processes using a vertical injection molding machine.

A mold assembly (1) for injection molding of a plastic pipe fitting (2, 3). The pipe fitting comprises an elbow-shaped or a tee-shaped internal flow channel (4). At least one of the first core member (14) and the second core member (15) of the core package (12, 13) comprises a built-in cooling arrangement (20) for cooling of the core package (12, 13), the cooling arrangement (20) extending longitudinally inside said core member over a substantial length of said core member. The pipe fitting (2, 3) comprises an elbow-shaped or tee-shaped internal flow channel (4) comprising at least two channel parts (5, 6, 7) arranged at a first angle (α) in relation to each other, the channel parts (5, 6, 7) each having a circular cross-section and a smoothly radiused inner corner face (8) between each two channel parts being at said first angle in relation to each other, the at least one of the channel parts having an inner diameter D, a length L from central corner point to the end of the channel part, the inner corner face having a rounding radius R. The ratio (D/R) of the inner diameter D and the rounding radius R is in the range 2 to 5, and the ratio (L/D) of the length L and inner diameter D is in the range 8 to 3.

A method of forming a mold insert used to produce an intraocular lens (IOL) mold is disclosed herein. The method includes providing stock material and cutting the stock material, which includes multiple cutting steps. The cutting steps are performed on transitional regions of supporting portions of the mold insert. Peripheral surfaces of the mold insert have varying roughness values, and supporting portions of the mold insert have a greater roughness than the optical portion of the mold insert. An IOL is also disclosed herein that is formed using an IOL mold that is injection molded using the mold insert. A method of forming the IOL is also disclosed herein.

A mould tool comprising: a first tool part defining a first mould cavity portion; a second tool part defining a second mould cavity portion; and, a cavity alignment system comprising: a temperature control system configured to control the temperature of a first zone of the first tool part to thereby effect thermal expansion and/or contraction in the first zone of the first tool part; a sensor configured to measure movement of a part of the first tool part in response to the said thermal expansion and/or contraction; and, a controller configured to control the temperature control system in response to feedback from the sensor to thereby control the position of the first mould cavity portion relative to the second mould cavity portion.

An injection mold is configured to form an eyeball for a fishing lure. The injection mold includes a first mold plate, a first stem plate, a second stem plate, and a second mold plate. The first mold plate defines a first injection port. The first and second stem plates and the second stem plate each define a plurality of stem cavities. The second mold plate includes first and second sides and a second injection port extending between the first side and the second side. The second side defines an iris cavity in fluid communication with the second injection port. The injection mold is configured to be assembled in a first configuration, to receive a first flowable material to form a pupil stem of an eyeball, and a second configuration, to receive a second flowable material to form an iris of the eyeball.

In a molding die, movable die elements are respectively received in die element receiving holes formed in a frame plate. An end surface of the frame plate, which faces a cavity at a location that is other than locations of the die element receiving holes, forms a frame portion compression surface. An end surface of each movable die element, which faces the cavity, forms a split compression surface. Die element drive devices respectively drive the split compression surfaces of the movable die elements. A whole compression plate commonly supports an opposite end part of the frame plate and opposite end parts of the movable die elements, which are opposite from the cavity. When the whole compression plate is moved forward, the whole compression plate integrally drives the frame plate and the movable die elements forward. A whole drive device drives the whole compression plate.
