摘要:
Die Erfindung betriff eine Vorrichtung (10) und ein Verfahren zum Formen einer aushärtbaren Formmasse (202), mit: - Aufnehmen einer aushärtbaren Formmasse (202), die sich in einem flüssigen Zustand befindet, in einer Kavität (14), die von einem ersten Formteil (100) und wenigstens einem zweiten Formteil (101) eines Formwerkzeugs (12) begrenzt wird; - Erzeugen wenigstens einer ersten Relativbewegung zwischen dem ersten und dem zweiten Formteil (100, 101), so dass sich die Kavität (14) verkleinert; - Aushärtenlassen der Formmasse (202).
摘要:
A process for casting TiAl components, having the following process steps: producing a melt (S) of the TiAl material below an inert gas fill (IF); placing a casting mold (1) on a gate (2) in a gastight manner; flooding the casting mold (1) with inert gas (IG) by opening a closure mechanism (7) which is arranged at the gate (2) and is connected to an inert gas source (8); pressing the melt (S) through the gate (2) into the casting mold (1) by increasing the pressure (P) of the inert gas fill (IF) above the melt (S) while at the same time evacuating the inert gas (IG) from the casting mold (1), and stopping the inflow of inert gas (IG) as soon as it is determined that the melt (S) passes above the position of the closure mechanism (7).
摘要:
Bulk metallic articles having a high-aspect ratio that are formed of bulk metallic glass, that are net-shaped and that are produced under process conditions that maximize the quality and integrity of the parts as well as the life of the mold tool, thus minimizing production costs, and manufacturing methods for producing such articles are provided.
摘要:
An apparatus for casting articles made of aluminum, aluminum alloys, light alloys and the like, comprising, on a platen (1), at least one lower die (2) and at least one upper die (3); a duct (4) for introducing liquid metal that approaches from below and is connected to a furnace leads into the lower die (2); the lower die forms a lower impression (10) which, in cooperation with an upper impression (11) of the upper die (3), provides a region for containing a dosed quantity of liquid metal; on the upper die, a flow control element (30) is provided that acts on the connecting port (5) of the feed duct (4), and a compaction plug (20), which forms a portion of the upper impression (11) and can perform a translational motion independently of the flow control element (30) in order to provide the article being cast.
