how are bike material processed to make suitable for bike parts?

Bike parts are almost like any other consumer products. There are many requirements to consider, like strength, safety, performance, appearance, cost, etc.\n\nYou start with the raw materials. Metals are forged, cast, stamped or drawn into desired shapes. Carbon fibre structures are layered according to desired strength requirements. Plastic & rubber parts are made by injection moulding.\nSome metal parts are then hardened, either by heat treatment or by aging. Then they might have to be machined to get the final shape.\nParts also undergo surface treatment processes to make it look good. Some are painted, polished, anodized, blackened, electroplated, etc. Lastly you have printing processes - to put the logos and the designs on the parts. This is either by pad printing, silk screen or simply using stickers. A growing trend is using a laser to burn the designs onto the parts.\n\nThe processes the parts go through depend largely on the selling price of the product. More processes (two-tone colours, accurate machining, intricate decorative designs, etc.) results in higher cost, and therefore higher selling price. Of course, higher price generally means higher quality.

kakani P wrote an excellent explanation but I wanted to add an example to help you furhter understand a practical application.\n\nThe tooth on the front of a backhoe bucket is a great piece to be carburized.  It could be made totally of high carbon throughout but that would make it brittle and subject to break since it experiences many impacts and shock loads as it encounters rocks (or old concrete from foundations being demolished) and other debris in the soil.  We still would like to have the surface hardened to reduce wearing but we still want the core to be ductile to prevent premature failure.  Carburizing allows us to "have our cake and eat it too".  We can make the surface wear resistent and hard but leave the core ductile and able to withstand large shock loads through the process of carburizing.

Here's the deal with shipping to an APO or FPO address. You CANNOT send it UPS. The Postal Service will. The main problem with shipping a bike Postal is that a standard bike box is too big for them to ship. They won't do it. So what you have to do is partially disassemble the bike and send it that way. Generally one box with the frame and a few small parts in it. Then another box with the wheels and everything else. Honestly it's a big pain, almost not worth it unless you can take it somewhere to be packed up byt someone that knows the shipping regs and knows the proper way to pack a bike.

My guess would be Duraluminium (an Aluminum alloy) orsome sort of titanium alloy... \n\nDuraluminium is used in harddisks as the ring separating the platters and in expensive bikes.

The type of plastic selected has a great influence on the performance of the plated plastic part. ABS plastics are the base materials in most cases.\n\nCheck out the following:

WOW!!  What a question! This is some form of raw material but not understanding what your question is. Email me so I have a better idea on what your asking,,,

I would think the best way to do this is to dry the sample and then turn it into a powder.  You could then perform an extraction of the metals possibly with Conc. HCL or HNO3.  There may be an organic solvent that could do this extraction but many of these solvents are not compatible with the plastics in AAS autosamplers.  Preparing the blanks would be the same as any other AAS standards.  Prepare an acid solution to match that of your sample and determine if and how much of each metal is present in your acid.  It is also good just for reference to run a blank of the water you are using.  When preparing the standards for the individual metals read some of the literature to determine the best method (ashing temp, atomization temps. etc.).  In many cases better results are obtained with the use of a matrix modifier.  I would read some literature and there should be many examples of this type of work.

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.

Hand crafted will mean just that, the frame will have been assembled by hand by a craftsman.  This is the norm for higher quality framesets.  On the other hand, it might mean that it has just been assembled by hand, although as this applies to all bikes.......\n\nCustom build is something different.  A custom builder will make a bike specifically for you, having taken your measurements he will build the frame and assemble the bike to your requirements.\n\nMy "best" bike is handmade, not custom made.  The shop where I bought it ordered a "standard" frame of an appropriate size (with the maker's name on it) and then set up the bars, saddle etc to suit me.  \n\nHope this has helped you.

Hard to say without a picture or to see the process. Gas pressure? Wind? Contaminants in the metal? Wrong gas mixture?\nHere's a couple of links that may help..

the frame is the heart of any bike, the fork attaches to it with a headset, the fork and frame together are called a frameset. the frame can be made of carbon, aluminum, titanium, or steel ( uslly a chromoly alloy ), from with it you attached the wheelset, the crankset, the stem, the handlebar, the seatpost, the seat, the rear cluster, the derailurs ( front and rear ), the pedals, the shifters, the brakeset.

America Speedster has both plans and kits for some very interesting quadracycles.  Some are built from pvc using hand tools and recycled bike parts.  See the link below.\n\nSometimes there are plans advertised on e-bay but some of them are just photocopies from old mechanics magazines.
