FAQ:

1.Q: What about leadtime ?

   A: Normally the leadtime is 60days after we receive the deposit and confirm  the details. All the press machines we use is the best quality in China Yangli brand. The press machine leadtime from Yangli is 50days,  the best leadtime we can give is 60days. 

 

2.Q: What's the lead time for moulds?

   A: Normally the mould leadtime is 45 days after we confirm all the details with customer. Our professional mechanical enginners from Austria will design the mould according to the samples from customer, or by the specifications offered by customers.    

 

3.Q:What kinds of mould you can make? and what is your strong point for the moulds?

   A: we can make wrinkle wall mould and smooth wall mould both. For wrinkle wall mould we can make, 79" pan, fish pan, bbq pan. For smooth wall mould we can make muffin cup, and cake cup, tar cup,etc. We can also make 2 or 3 portion conatiner moulds as long as you offer us sample or specifications.  Our strong points are all our moulds are WEDMLS cut, which makes the mould more accurate and precise. Important materials likestainless steel parts we make in Austria. We also recut after heat treatment, which most of makers do not take this process.

Q:What are some unushal properties about Aluminum?
Aluminum is a versatile material with vast applications in engineering, aerospace and automotive industries. Some of its desirable properties include lightweight (relative to steel) and high strength. The metal is however rarely used in its pure form, it is often alloyed with other elements such as Mg, Manganese, chromium, Titanium to fine tune its mechanical, chemical and or physical properties and tailor it to specific applications. However, in some applications other materials are preferred, for example, Magnesium, due to its higher strength to weight ratio is increasingly replacing Al in transmission casing of automobiles. Also, Compacted Graphite cast Iron is preferred in engine blocks because of its superior strength at high tempreatures, dimensional stability and wear resistance. Auto engines work at very tempreatures and alloys that are capable of withstanding high pressures while maintaining stability are critical. CGCI performs better than Al in this situation. Al alloys remains an important engineering materials though.
Q:Excuse me: how much is the price of the thick 3mm 1000 *2000mm aluminum sheet per square meter?.
(current aluminium ingot price is about: 15000 yuan / ton, plus board processing fee 2000/ tons, =18000 yuan / ton)2.71*3mm* aluminium plate price 18 yuan / kilogram, =146.34 yuan / square.2MM*2.71* price 18 yuan =97.26 yuan / square.Is the aluminum plate with a thickness of more than 0.2mm to 500mm, 200mm width, length less than 16m aluminum material called aluminum plate or aluminum sheet, aluminum is below 0.2mm, 200mm within the width of the row material or bar (of course, with the progress of the large equipment, the width can be 600mm row material also more).
Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
Because there is oxide on the surface of aluminum, the reaction will be quicker after polishing the oxide with abrasive paper.
Q:Why does Aluminum rust is electron orbitals?
'Rusting' commonly refers to the corrosion (oxidation) of iron so when talking about other metals, it is better to use the term 'corrosion' or 'oxidation'. Aluminum can corrode and the fact that it has a general oxidation number of +3 doesn't really matter. Many elements which have a charge that is different from +2 can oxidize. Alkali metals for instance (which have a charge of +1) can oxidize. Lithium can form lithium oxide (Li2O), sodium can form sodium oxide (Na2O) and so on. However, aluminum is known to be quite resistant to corrosion (oxidation) because it spontaneously forms a thin (solid) oxide layer at it's surface protecting it from further oxidation whereas iron, for an example, will easily lose that thin layer (it ''peels off easily'') exposing more iron to corrosion. So since Al has a +3 charge and O has a -2 charge, you'll need 2 atoms of Al and 3 atoms of O to make an electrically neutral compound. 2 atoms of Al = +6 charge 3 atoms of O = -6 charge Hence Al2O3 which is aluminum oxide. I hope it helps.
Q:How well does aluminum hold up in chlorinated pool water?
It should hold up well I don't think there would be any reaction. They use aluminum railings as stairs for large pools. The aluminum might be coated with something else though. Aluminum usually forms a thin coat of Aluminum Oxide, Al2O3, so it should prevent it from further oxidation.
Q:please suggest metal similar to aluminium with casting properties?
Aluminum is lousy for casting because it shrinks and tears. However you can add about 2% finely divided steel and get a useable alloy. It is better to use what everybody else uses: pot metal. Any junk yard can provide an endless supply of carburetor bodies which you can melt at fairly low temperatures and get nice strong castings. If you can locate some ancient floppy drives or dot matrix printers you will get a prettier alloy.
Q:What does exterior wall imitate aluminium paint have? Imitate aluminium plate paint is fluorocarbon paint?
If not missing the cost or use aluminum plate, because the fluorine content of fluorocarbon metal paint paint factory production lot are not enough, so the warranty 10-15 years is just a pretext, and the construction of the technical requirements for workers is relatively high.
Q:Performance differences between aluminized and aluminized plates
Brief introduction of hot dip aluminizing of steelHot dip aluminizing of steel is a new type of coating process for forming alloy aluminum layer on the surface of steel when molten steel products are inserted into molten aluminum liquid at a certain temperature.Hot dipped aluminized steel has high strength of steel matrix and corrosion resistance, wear resistance and high temperature resistance of aluminum layer. Its corrosion resistance is 5-10 times that of galvanized steel; it is resistant to sulfide and heat corrosion. Its performance is better than 18-8 stainless steel. Therefore, it can bring obvious economic benefits to users.
Q:What is aluminum foil made of?
It is not aluminum oxide. It's pretty much pure aluminum, though it may be coated with a very thin layer of wax or plastic. As for the independent experiment, be careful and wear goggles and other protective clothing. I was in high school once too, and can tell you from experience that thermite burns very, very hot and is quite good at melting or combusting a wide variety of materials. It also requires a fairly hot ignition source, and magnesium strips are often used for that purpose as a kind of fuse. If you don't have access to that, figure something else out, but do *not* attempt to light thermite directly with a blowtorch. You want to be much farther away by the time it lights, and it would be a bad idea to lay the torch there and back away because that places the torch's potentially explosive fuel supply much too close to the reaction.
Q:When you mix sodium hydroxide with water then add aluminum hydrogen gas is given off, is this from the water?
Aluminium does not normally react with water because of a surface coating of the highly unreactive Al2O3 that forms on exposure to atmospheric oxygen. In the presence of strong base, however, this compound dissolves due to complexation by hydroxide, similarly to how silver chloride dissolves in ammonia. Al2O3(s) + 2OH-(aq) + 3H2O(l) ----- 2[Al(OH)4]-(aq) Once this has occured, aluminium metal, a very strong reducing agent, is exposed to water. 2Al(s) + 6H+(aq) ----- 2Al3+(aq) + 3H2(g) Even though the solution is alkaline, there is still a low concentration of H+ formed by the autoprotolytic dissociation of water. The Al3+ formed then reacts with hydroxide to produce more [Al(OH)4]-. Yes, the hydrogen gas is from the water.
