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:how to avoid oxidation of aluminum sheet after wire drawing?
leave it alone after wire drawing!aluminum sheet will formulate a layer of dense oxide film. So you don't need to worry about it! Don't often polish the aluminum wire, or they will be more and more slimsy, the oxide film is used for avoiding reoxidation.
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.
Q:how to connect copper pipe and aluminum sheet?
welding!
Q:how to produce aluminium sheet circle?
As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
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:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
It’s possible, there are several problems: 1, workers won’t wipe it thoroughly and fully, so you can wipe it after soaking. 2, the wiping efficiency is low, and we can use ultrasonic to clean it. 3, the water is poisonous and harmful to environment and workers’ health, so you can use water base to clean it, environmental and non-poisonous. Of course, if you really want to change, you can use detergent special for aluminum materials cleaning of our company, Changlvfeng chemical industry company. a, its PH value is 6.8-7.2 and it is totally an neutral liquid. b, good material applicability, detergent invented for aluminum materials. c, good degreasing ability, it has a good degreasing function for various oil contamination in processing and has no effect on material.
Q:which kind of enterprises are aluminium sheet circles used in?
user use cold squezz method to transform the aluminum sheet circle into various standard capacitor shell, aluminium collapsible tube shell, which are broadly used in electron industry, daily chemical industry, medicine, education and automobile products,electrical appliance, heat preservation, machine manufacturing, automobile,spaceflight,military industry,mould, construction, printing and other industries.
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:why intact aluminum sheet stop quicker than pectinate one in the magnetic field?
while swinging in the magnetic field, intact aluminum sheets will formulate inner eddy current,that is the annular induced current.eddy current will transform the mechanical energy into heat energy, which makes the aluminum sheet stop quickly.but pectinate aluminum sheet can't formulate intact eddy current, so intact aluminum sheet stop quicker than pectinate one.
Q:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
