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:how to process 0.3mm hole on aluminum material?
punching wire-electrode cutting
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:Could ring-pull can be transformed as aluminum sheet?
Yes, but the ring-pull cans contains fewer aluminum.
Q:Which kind of glue is best for bonding wood and aluminum sheet together?
You can use 502 adhesive.
Q:Could induction heating fuenace be packaged with aluminum foil as insulation material?
Aluminum foil can’t be used for heat retaining, it’s unsafe and hasn’t good efficiency. In this case, advice you use refractory cement to knot the coil and connect porcelain tube in the middle. It will Largely reduce the energy consumption produced by heat radiation.
Q:why does aluminum sheet not react with sulfuric acid nut react with hydrochloric acid?
aluminum reacts with hydrochloric acid,generating aluminium chloride which can dissolve in water. but aluminum reacts with sulfuric acid, generating aluminum sulfate which can't dissolve in water and will generate aluminum sulfate, a layer of protective film, preventing aluminum from reacting with sulfuric acid, so there is no significant phenomena.
Q:why could aluminum pot be repaired by knocking the aluminum sheet into the pot but not being bonded by glue?
the oxidation rate of aluminum's surface is very quick, so we cann't use the method of tin welding, and the cost of argon arc welding is very high,so aluminum pot's repair usually uses riveting. aluminum has low hardness and good ductility, so it can be repaired by tightly knocking, without the bonding of glue. general glue will decomposed in open fire, if we bond pot by glue, the pot after repair won't be able to endure high temperature.
Q:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought will know their defferences from their definition.
Q:Which kind of glue is best for bonding aluminum sheets?
502 or universal glue
Q:what will happen when aluminum sheet is put into copper chloride solution?
the chemical equation of the reaction, 2Al+3CuCl2=2AlCl3+3Cu, the phenomena when aluminum sheet is put into copper chloride solution: there is red solid generating on the surface of aluminum sheet.
