Engineering Castings History

Engineering Castings Iron is a common element in the earth's crust, but it almost always occurs as a compound: it is very rare to find it naturally as metallic iron. It's not known when human beings first discovered how to smelt iron ore to produce useable iron. The oldest-known iron objects, found at two sites on the banks of the Nile, are beads made of iron derived from meteorites, which date fr...

Die Castings & Automotive...

DIE CASTINGS-AUTOMOTIVE PRESS Moulding methods have altered little over the years, most involve the use of a solid patterns made from wood, resin or aluminium onto which sand is rammed. When the pattern is removed a cavity is left in the sand which represents the outside form of a casting. In order for the pattern to be drawn out of the sand, taper is left on the pattern. The problem is that all t...

SeaGen Project - Turbine...

Case Study for SeaGen Turbine Housing Casting The casting illustrated in these videos was designed for the Seagen project (a 1.2MW tidal energy convertor installed in Strangford Lough) which generates electricity from tidal currents. The casting was designed to carry two 8 metre variable pitch rotors and house the actuation necessary to change the angle of attack of the rotors to take account of t...

SeaGen Raised & Operating...

Case Study for SeaGen Turbine Housing - Continued Increasingly sg iron is being seen as a viable alternative to the traditional materials used in salt water and other corrosive environments. When this is combined with it's higher strengths when compared to cast iron castings, designers are becoming more confident in specifying it's use. The pictures showing SeaGen in it's raised and operating posi...

S.G. (ductile) irons

Metals Cast SG Iron also referred to as Ductile Iron-ASTM A536 Typical Uses of SG/ Ductile Iron This is the American standard for sg or ductile irons broadly equivalent to BS EN 1563 and has similar uses. Automotive press dies, pressure containing castings, pump castings, bearing housings and general engineering parts where greater elongational strength and impact resistance is required than is fo...
