METHOD AND DEVICE FOR INJECTION OVERMOULDING
The invention concerns an injection overmoulding device comprising at least one indexed rotary turret on which cooled moulds are installed, each mould comprising a plurality of cavities, and at least five stationary stations arranged around said turret, including at least a first station, a second station and a third station that are used, respectively, for carrying out the operations of positioning the inserts in the cavities of the mould, injecting plastic material into the cavities of the mould, and demoulding the at least partially cooled objects. The device comprises, for each mould, at least separate injection means. The invention also concerns a method implemented by the device.
Surface Fastener Molding Apparatus and its Operational Method, and a Method for Producing a Surface Fastener
A surface fastener molding apparatus includes a supporting structure and a second supporting structure for axially supporting a mold roll in a rotatable manner at a first end side and a second end side of the mold roll which is opposite to the first end side. The mold roll includes a circumferential surface in which a plurality of mold cavities for molding engaging elements of the surface fastener is provided. A first linear driving means and second linear driving means are provided which are for, respectively, advancing or retracting the first supporting structure and the second supporting structure. The degree of closeness between the extruding nozzle and the mold roll is regulatable across the first end side and the second end side of the mold roll, based on at least one activation of the first driving means and the second driving means.
Rotary Dough Molding Machine
A rotary dough molding machine (10). The machine has a frame (6), a die roller (4) and a feed roller (5) rotatably mounted to the frame (6) and an adjuster that adjusts the gap between die roller (4) and feed roller (5), wherein one of the rollers (4, 5), is an adjustable roller, which is movable relative to the frame (6) by the adjuster. The adjusting has a first drive (1) acting on the first end (51) of the adjustable roller (5) causing a movement of said first end (51) in a first direction (x) transverse to the rotational axis (50) of the adjustable roller (5), and a second drive (2) acting on the second end (52) of the adjustable roller (5) causing a movement of said second end (52) in a second direction (x) that is essentially parallel to the first direction (x). The first drive (1) and the second drive (2) can be actuated independently of each other.
Press molding apparatus and press molding method
A press molding apparatus includes two dies and press-molds a heated stampable sheet into a predetermined shape by using the two dies. The press molding apparatus includes a movable core provided in at least one of the two dies. The movable core is disposed at an inward side of an edge portion of a cavity. When receiving a pressure greater than or equal to a predetermined value, the movable core moves in such a direction that the cavity increases in volume.
DEVICE FOR FORMING THIN FILM MEMBER AND METHOD OF FORMING THIN FILM MEMBER
A thin film member forming device includes a reference roll fixedly disposed while being rotatably supported by a first bearing member, a movable roll disposed movably with respect to the reference roll while being rotatably supported by a second bearing member, a roll gap adjusting mechanism which adjusts a gap between the reference roll and the movable roll and a roll opening mechanism which expands the gap. The roll gap adjusting mechanism adds a load in a direction to narrow the gap to the second bearing member, and the roll opening mechanism adds a load in a direction to expand the gap to the second bearing member.
Optical Polymer Films and Methods for Casting the Same
An example system is configured to photocure a photocurable material to form a polymer film. The system includes a first chuck configured to support a first substantially planar mold, a second chuck configured to support a second substantially planar mold, and an actuable stage coupled to the first chuck and/or the second chuck. The actuable stage is configured to position the first chuck and/or the second chuck so that the first and second molds are separated by a gap. The system also includes a sensor arrangement for obtaining measurement information indicative of a distance between the first and second molds and/or a pressure between the first and second chucks at each of at least three locations. The system also includes a control module configured control the gap between the first and second molds based on the measurement information.
