28 Jan 2000: Economics. We've already ruled out machining on cost grounds. Can any of the other processes be ruled out because of cost? ... We're going to want to make millions of pins, so we need a process with an appropriate economic batch size.

25 Feb 2002: Processing information. A process encyclopedia containing details on how processes work as well as useful selection information such as possible materials, shapes, economics etc.

4 Sep 2001: It is not economic to use standard processes such as turning - so another approach is needed.

8 Sep 2001: Economics. Milling machines vary in price from £1,000 to £1,000,000. Milling is generally a very slow way to produce a component - but it can be economic for prototyping

8 Sep 2001: Economics. The machinery is expensive, and can cost well over £100,000 for HIPing. ... Because there is little competition, can be economic for small batches (1,000+) - although still not cheap!

30 Jan 2002: The compression test is similar but uses a stocky specimen to prevent bending.

8 Sep 2001: Economics. For making stock items, rolling has few competitors.For this reason, it is usually performed by the foundries before passing on to customers for further processing. ... For long shaped sections, rolling is the only viable option for larger

30 Jan 2002: The compression test is similar but uses a stocky specimen to prevent bending.

8 Sep 2001: However, the production rate is slow so it is only economic for one-off jobs, repair work and difficult access situations. ... Joining of sheet (e.g. car body panels) is usually more economic by other welding processes such as spot welding.

30 Jan 2002: The compression test is similar but uses a stocky specimen to prevent bending.

8 Sep 2001: Economics. Equipment is generally low cost, except where automation is used. ... Wave soldering is the most economic means of soldering large batches of printed circuit boards.

30 Jan 2002: Speed is critical is disassembly is to be economic. In general, the more different materials used in a product, the harder it will be to recycle them.

8 Sep 2001: Cold extrusion is possible for some metals giving better properties. Economics. ... Usually only economic for several thousand metres. Typical products. Tubing. aluminium window frames.

7 Sep 2001: it is the same whatever the size of the test-piece. Many applications require stiff materials, e.g.

30 Jan 2002: A series of tests are carried out with the specimens in a furnace.

8 Sep 2001: Economics. The machinery is expensive, and can cost well over £100,000. ... Because of the high capital cost, the process is only economic for batches of 100,000+.

8 Sep 2001: Economics. The basic equipment cost is low - from £500 to £3,000; automation and higher temperature furnaces can increase this a lot. ... The labour intensive nature of the process mean it is usually only economic for small batches, although dedicated

20 Jan 2000: Every product is designed in a particular way - product analysis enables us to understand the important materials, processing, economic and aesthetic decisions which are required before any product can be manufactured. ... Choose a suitable process that

7 Sep 2001: Simple Questions. Why is it economic to recycle aluminium cans but less so for steel ones? ... Why will new reserves of minerals/oil which are not now economic to mine become economic in the future?

5 Sep 2001: Devising simple material tests is an important aspect of appreciating which properties are important in a design, and the challenges in obtaining meaningful, relevant material data.
