MULTI-CAVITY COMPRESSION MOLDING
An assembly for compression molding includes an insert housing defining a plurality of apertures having stop surfaces. The assembly includes a plurality of inserts disposed within the apertures and in engagement with the stop surfaces. The assembly further includes a plurality of gas springs in biased engagement with the inserts. Individual gas springs of the plurality of gas springs are adapted to independently compress under load to permit independent movement of individual inserts within the apertures relative to the insert housing.
Tooling element and methods for forming and using same
A tooling element includes a flexible sleeve defining an interior cavity. The flexible sleeve includes a sealable access port extending through the flexible sleeve from the interior cavity to an exterior of the flexible sleeve. The tooling element further includes vacuum-packed tooling particulate disposed within and filling the interior cavity of the flexible sleeve.
Imprint pattern forming method
An imprint pattern forming method includes contacting a template with a pattern in a front surface with an imprint material formed in a substrate to fill the imprint material into the pattern, curing the imprint material filled in the pattern to form an imprint material pattern, and after forming the imprint material pattern, separating the template from the imprint material pattern while applying pressure to the back surface of the template.
Curing mold for manufacturing a turbomachine component made of composite material from a preform and method for producing a component by means of such a mold
A curing mold for manufacturing a turbomachine component is made of composite material from a preform, including: a first and a second body defining an air gap receiving the preform; at least one primary channel arranged in the first and/or the second body; an injection member of a pressurized fluid in the primary channels; at least one secondary channel, in which a piston slides, which delimits, on the one hand, a first chamber in communication with the or a primary channel and, on the other hand, a second chamber in communication with the air gap, and which is designed to compress thermosetting resin which has entered the second chamber from the preform in the air gap, so as to put the preform under hydrostatic pressure.
Die apparatus
A die apparatus capable of removing powder adhering to cut surfaces so as to securely form a cavity in a desired shape includes divided dies reciprocatingly driven by sliders to comes into contact with one another so as to form a cavity. Punches are inserted into the cavity from above and below the cavity. Each divided die is provided with cut surfaces that come into contact with the other divided dies. A gas passage connected to a gas injection port that injects gas from the cut surface is formed in each divided die.
CURING MOLD FOR MANUFACTURING A TURBOMACHINE COMPONENT MADE OF COMPOSITE MATERIAL FROM A PREFORM AND METHOD FOR PRODUCING A COMPONENT BY MEANS OF SUCH A MOLD
The invention relates to a curing mold (10) for manufacturing a turbomachine component made of composite material from a preform (200), comprising: a first and a second body (11, 12) defining an air gap receiving the preform; at least one primary channel (21) arranged in the first and/or the second body; an injection member (22) of a pressurized fluid in the primary channels; at least one secondary channel (23), in which a piston (24) slides, which delimits, on the one hand, a first chamber (26) in communication with the or a primary channel and, on the other hand, a second chamber (27) in communication with the air gap, and which is designed to compress thermosetting resin which has entered the second chamber from the preform in the air gap, so as to put the preform under hydrostatic pressure.
