...technique. Sub-assembly sideways tooling is quite complex with the use of slide cones. Tool life on hot forging small steel components is low. Tool life is better on hot forging brass components, since this is done at lower temperatures than for steel. Materials: Material range is restricted to those that produce acceptable die and punch lives. Steel components can be...

...techniques such as firing lasers at certain minerals, I can gain precise information about when the granites formed, some 30 to 40 million years ago. These analyses can also provide us with detailed information about the temperatures and pressures the rocks experienced. So by investigating the rocks at a very small scale I can then identify processes happening at a larger...

...technique for extracting the important ideas from a situation, conversation, presentation or written article and getting them down on paper in a way that is meaningful to you. A spray diagram starts from a theme in the centre and the ideas arrange around that theme showing the connections or associations between the ideas. Sometimes it is useful to introduce a small...

...technique. Vertical casting through large in-gates reduces porosity problems due to air entrapment and prevents spray injection into the die cavity. Design: Used for similar applications to those used for conventional high pressure die casting. The major application is for automobile wheel rims in aluminium alloys. See Also: High pressure die casting, Low pressure die...
