...types: “cold-chamber” and “hot-chamber” processes..."Cold-chamber" high pressure die casting Molten metal is poured into a cold shot chamber. A high pressure single plunger forces metal into the single or multi-die cavity. [Image of "Cold-chamber" high pressure die casting] "Hot-chamber" high pressure die casting A gooseneck hot chamber is submerged in a pot of...

...Design: Process can only be applied to vertical, flat, butt-type welds. Used for welding thick plate sections (20–2000 mm thick). Used for welding ships, large containers and heavy engineering structures. Allowance for large amounts of transverse shrinkage on cooling, e.g. 5 mm on 50 mm thick plates.

...type of material: pure aluminium 70 m min-1 heat treatable Al alloy 1 m min-1 Backward extrusion is used to produce hollow components having a closed end, by forcing a smaller-diameter punch into the slug so that metal flows around and back up the punch. Hydrostatic extrusion uses a hydrostatic pressure of a fluid on all sides of the billet to force the billet through the...
