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:is there aluminum oxide on the surface of aluminum sheet after being polished by abrasive paper?
aluminum will be oxided as aluminum oxide once being exposed in air.
Q:which kind of material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
Q:does aluminum sheet has a function of magnetism isolating?
yes.
Q:How to clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
you can answer sodium hydroxide solution, dilute acid is useless, aluminum's oxide film is very thick,as for concentration, aluminum will be passivating in concentrated sulfuric acid. if you are high school student,higher concentration is better, you can complete deoxidation by abrasive paper.
Q:Could copper wire be welded with aluminum sheet?
Copper wire could be welded with aluminum sheet, and it needs to use low temperature welding method, if copper wire is in the unit of millimeter and aluminum sheet is also in the unit below 1 mm, you can use electric soldering iron to heat it as hybrid welding and choose low temperature welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. As for the large aluminum sheet, you can take liquefied gas multihole lance as heat source, then choose the same low temperature materials as welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. Welding fundamentals of these two welding methods: both of them are use heatable heat source to heat the matrix to 179 degree, the melting point of WEWELDING M51, then use matrix’s heat conduction to melt welding wire, completing welding. The process of melting welding wire is the process of smearing the welding wire with flux into welding area, melting welding wire completely depends on matrix’s heat conduction.
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:Which kind of glue is best for bonding wood and aluminum sheet together?
cm2, leather. 4, it’s durable and can endure 106 degree high temperature. Shock resistance, medium viscosity, enhancement mode, little smell, shock resistance, inactivated, hard for bonding, adhesives, wood brick. 480, little white sediment, bonding, acidity, 410。 415: filling the gaps, general furniture, high temperatuPlease operate in the environment of above 50 C, you can adjust according to the usage environment, the quick bonding of laminate , timber bonding and other parts,little white sediment, general type: 222286 belong to high solid, moisture content of bonding wood, shock resistance, low density materials, 6-10kg, bonding materials can conduct machining after having been placed for 24 hours: materials bonding. 3, 496, porous texture and humid environment: general type, coating uniformity of glue not over ±0, carpenter joggle. 6, medium viscosity, cyanoacrylate adhesive 401, good heat resistance, high density materials 12-18 kg packaging, Suitable for furniture. 414 (1) Formica, carpenter’s glue,
Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
no, but I'm not certain.
Q:How to distinguish aluminum sheet from magnesium sheet?
seperately put aluminum sheet and magnesium sheet into NaOH solution, the one generating bubble is aluminum sheet, because aluminum sheet will react with strong base , generating hydrogen.
Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
