Hot Form Quench (HFQ) is an aluminum hot stamping process for high strength sheet (typically) 2xxx, 6xxx and 7xxx series alloys, [6] that was initially developed in the early 2000s by Professors Jianguo Lin and Trevor Dean at the University of Birmingham and then at Imperial College London, both in the UK.
Thick or heavy-gauge thermoforming also requires tooling specific to each part, but because the part size can be very large, the molds can be cast aluminum or some other composite material as well as machined aluminum as in thin gauge. Typically, thick-gauge parts must be trimmed on CNC routers or hand trimmed using saws or hand routers.
The superforming process varies mostly in the way that the metal is introduced to the form; the main 4 variations are: Cavity forming The metal in its plastic state is introduced to a negative form by gas pressure. It is good for large and complex parts such as automotive body panels and is excellent for shaping 5083 aluminium alloy.
Investment casting has been used in various forms for the last 5,000 years. In its earliest forms, beeswax was used to form patterns necessary for the casting process. Today, more advanced waxes, refractory materials and specialist alloys are typically used for making patterns. Investment casting is valued for its ability to produce components ...
Aluminum forms a eutectic with silicon, which is at 577 °C, with a Si content of 12.5% [7] or 12.6%. [8] Up to 1.65% Si can be dissolved in aluminum at this temperature. However, the solubility decreases rapidly with temperature. At 500 °C it is still 0.8% Si, at 400 °C 0.3% Si and at 250 °C only 0.05% Si.
Superplastic forming is an industrial process used for creating precise and complex ... The major advantage of this process is that it can form large and complex ...
The fluid is injected into the tube through one of the two axial punches. Axial punches are movable and their action is required to provide axial compression and to feed material towards the center of the bulging tube. Transverse counterpunches may also be incorporated in the forming die in order to form protrusions with small diameter/length ...
Aluminium–manganese alloys (AlMn alloys) are aluminium alloys that contain manganese (Mn) as the main alloying element. They consist mainly of aluminium (Al); in addition to manganese, which accounts for the largest proportion of about 1% of the alloying elements, but they may also contain small amounts of iron (Fe), silicon (Si), magnesium (Mg), or copper (Cu).
