comparison between forging and casting?
148385
Forging is the process of shaping metal by use of heat and hammer. Whereas, casting is a process by which a material is introduced into a mold while it is liquid, allowed to solidify in the shape inside the mold, and then removed producing a fabricated object, part, or casing.

Depends on what you are fabricating. \nAre you talking about making the material itself or fabricating structural components from stainless materials?\n\nAnd what type of material? What grade of stainless? What configuration? Angle iron or I-beam? Welded or bolted?\n\nSounds like you need to talk with an experienced estimator and/or structural engineer.

Cast is melted and poured, wrought is pounded and formed in a semi-solid to solid state.

You may be casting on incorrectly. Or perhaps looping the second row incorrectly. It's hard to give advice over the internet, but you could try this website: learntoknit.com ?

Better than that, look up some standard tables, be careful with the yarn, SiC is extremely hard.

You basically need information on metal manufacturing, casting, and molding.  Not really something that can be done at home.

Reproduction detail\n1. use of finer sand, \n2. Hydrostatics of the molten metal \n3. same as in #2\n4.Hmmm?\n5.To avoid air voids :). \n6. Not enough water and the sand will crumble, too much water the medium will be too fluid or too much of steam will be produced during casting damaging the mold from inside out.

a mould is a container of a specific shape into which a molten solid is poured and left to set into the shape of the mould.\nA die is basically a hole through which semi-molten solid is forced under pressure and it will solidify which the cross-sectional shape of the die.

go to your blacksmiths ( i recommen WH Blacksmiths) don't forget to take about a ton of iron ore with you this can be found in Mordor or just that massive mountain by your house boy, after you have mined there and taken the ore in a wheelbarrow to the blacksmiths (or public forge) smelt the iron in the forge until it becomes soft and creamy, use a small tea spoon and if it melts in the ore then its ready. Pour the contents onto a bracket of somesort (please search on yahoo for the proper name) and pour cold water over the mould to cool the ore and create a chemical reaction. Get a big hammer and whack the sword and shield in to shape, hammer it in the morning and hammer in the evening just hammer all over the "stuff". Once you have zen. You can now sharpen the sword on a wheel and one of those foot pedals that make the wheel spin, lots of sparks will fly off, so wear protective goggles and ask an adult to help you. Tie a piece of string to the shield as a handle (at this point you will probably be on the school bus trying to get everything perfect and finished so this will save time). Sorry I cannot help you make a flail, try Walmart. Hope this helped , I made a shield and sword for my sons "Narnia" playset.

Plaster mold casting may work.\n\n"In plaster mold casting, a plaster, usually gypsum or calcium sulfate, is mixed with talc, sand, asbestos, and sodium silicate and water to form a slurry. This slurry is sprayed on the polished surfaces of the pattern halves (usually brass). The slurry sets in less than 15 minutes to form the mold. The mold halves are extracted carefully from the pattern, and then dried in an oven.\n\n"The mold halves are carefully assembled, along with the cores. The molten metal is poured in the molds. After the metals cools down, the plaster is broken and the cores washed out."\n\nI don't know what finished product you plan to make. You say you want to duplicate a glass bottle, but does that mean you want to do it in glass, or will you do it in plastic or some other material? I don't know if this process would stand the temperature of molten glass. In that case you would be better off with what is called "refractory mold material." Both the plaster and the refractory material should be available from a Dental Laboratory supplier.\n\n"Low temperature melting materials such as aluminum, copper, magnesium and zinc can be cast using this process. This process is used to make quick prototype parts as well as limited production parts. "

morpheous is also good but the same applies be careful i recomend not dowloading any .exe files most are backed with trojans (experience)

By putting a metal cast over it.

Copper has a higher melting and boiling point and better electrical conductivity.\n\nIf you are a die caster, Zinc would be better because it can be easily pressure die-cast and hence better accuracy in the cast component with minimal metal removal for finishing.

Actually these are all loops to be used in different situations.\n\nThere are no considerable performance diffrence between these. All when compiled achieves almost same form. But some common strategical used are described below. No need to adhere to these u can use whichever u think appropriate for situation and moreover code must be easily understanadable\n\nFor Next loops are used  when u know the limits of iterating variable and iterating variable is a numeric value\n\nDo While\n\neg Do While Not EOF\n      Load(<some data>) to GridView\n   Loop\n\nDo Until are usually used to achieve a target.\n\neg Do Until Not EOF\n      find(<something>)\n   Loop
