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:which kind of abraser should be used for deburring of aluminum sheet?
as for the polishing of aluminum material, we usually nylon wheel and similar products.
Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:How to solve the loose bonding of aluminum sheet and silica gel?
Bonding silicone rubber needs surface treatment, after using silicone rubber surface treating agent of Kuer , you can bond them with 4211 adhesive.
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:what's the size of aluminum sheet circle?
aluminum sheet circle's texture 1060, 3003 thickness 0.4-5.0mm, diameter 190-760mm.
Q:What are the colors of iron sheet and aluminum sheet?
silver white
Q:has aluminum sheet reacted with concentrated sulfuric acid?
it can be regarded as no reaction, concentrated sulfuric acid will make aluminum's surface inactivation,and produce a layer of dense aluminium oxide film which will prevent further reaction.
Q:How to distinguish aluminum sheet from magnesium sheet?
put two sheets into excess NaOH. The one that reacts with NaOH, generating sediment, is magnesium sheet,(sediment, but Al(OH)3 is amphoteric:Mg(OH)2) another one without sediment is aluminum sheet(in fact, there is sediment Al(OH)3, but it will react with alkali,)
Q:does aluminum sheet has a function of magnetism isolating?
copper sheet is better.
