Abstract: A metal flow system, for high pressure die casting of alloys using a machine having a pressurized source of molten alloy and a mould defining at least one die cavity, defines a metal flow path by which alloy received from the pressurized source is able to flow into the die cavity. A first part of the length of the flow path includes a runner and a controlled expansion port (CEP) which increases in cross-sectional area, in the direction of alloy flow, from an inlet end of the CEP at an outlet end of the runner to an outlet end of the CEP. A CEP exit module (CEM) forms a second part of the length of the flow path from the outlet end of the CEP. The increase in cross-sectional area of the CEP is such that molten alloy, received at the CEP inlet end at a sufficient flow velocity, undergoes a reduction in flow velocity in its flow through the CEP whereby the alloy is caused to change from a molten state to a semi-solid state.

Abstract: The invention relates to a method for the weight-accurate filling of ingot molds in a non-iron casting machine, e.g. a copper anode casting machine or a zinc anode casting machine, which is configured in the form of casting wheels that are use for production in a fully mechanized casting operation and are provided with the ingot molds. The aim of the invention is to obtain the desired precise-weight quality of a piece and exact plane parallelism of the bordering surfaces thereof. Said aim is achieved by carrying out the following steps: first, a liquid metal is introduced into an intermediate trough (4, 4?) at a regulated mass flow rate, the continuous dynamic weight increase being simultaneously determined; second, liquid metal is fed into a dosing trough (4, 4?) which is located on each side of the intermediate trough (4, 4?) by alternately tilting the intermediate trough (4, 4?) on one side followed by the other.

Abstract: A method for gluing and brazing a honeycomb structure includes at least one partially structured foil with a pitch and a wave height. The method includes the steps of choosing a mean brazing material diameter of a powder brazing material, said diameter being 15% smaller than the height of the wave; determining a minimum thickness of the glue strip according to equation; gluing at least partially structured foil within the width of the glue strip on at least part of the wave crests formed by the undulation; brazing the honeycomb structure. The invention also relates to a corresponding honeycomb structure that ensures satisfactory joint connections even when said structure is used in the exhaust systems of automobiles.

Abstract: The present invention is a method for casting a part having a complex shape or having a complex shape thereon. The method includes providing a pattern and securing at least one core to the pattern. A conformable material is located about the pattern and the core to create a complementary shape to the pattern and core in the conformable material. The pattern is removed and the core is left behind in the conformable material. The core leaves space, or an empty form, for a negative draw that cannot be formed in known casting methods. A mold is located adjacent the shaped, conformable material. A hardenable material is located between the mold and the shaped, conformable material and into the core. The hardenable material is allowed to harden and then it is removed. A cast part having a complex shape, or having a complex shape integrally formed with the part, results.

Abstract: An apparatus and method for joining structural members to form preforms and structural assemblies are provided. The structural members are positioned so that joining surfaces thereof define an angled aperture, such a slot or frustoconical bore, that receives a corresponding joining member. The joining member is urged into the aperture against the joining surfaces and moved, for example, by oscillating or rotating the joining member, to friction weld the joining member to the structural members. Each structural member can include a clamping portion that is received by a clamping device that prevents the aperture from opening as the joining member is urged into the aperture. A gripping portion of the joining member and the clamping portions of the structural members can be trimmed from the resulting preform to form a finished structural assembly.

An annular permeable wall member is mounted in the mold body adjacent the inlet end of the mold cavity with an inner face thereof forming an interior face of the mold. A refractory transition plate is mounted at the inlet end of the mold cavity, this transition plate providing a mold inlet opening having a cross-section less than that of the mold cavity. This provides an annular shoulder at the inlet end of the cavity. Means are provided for feeding molten aluminum through the inlet opening. Separate conduits are also provided for feeding a gas into the shoulder and via the permeable wall means for providing a layer of gas between the metal and the inner face of the mold. A gas that is more reactive with molten aluminum is fed into the shoulder and a less reactive gas is fed via the permeable wall.
