Product Description:

1.Structure of Bottle Cap Aluminium Sheet and Coil Description

Aluminum Sheet for bottle closure is rolled to very fine tolerances to yield more closure per tonne of stock and to allow uninterrupted operation of high-speed, multiple-cavity presses. Such closure sheet its strength, high formability, low Earring and printable surfaces make it ideal for pilfer-proof caps and vial seals.

Closures from Signi assure long storage periods without any deterioration of the product. With suitable removal torque and high quality multicolour printing, its ROPP Closures are aesthetically unique and technically user friendly, perfect for re-sealability.
The broad categories of ROPP closures can be defined as Plain Printed Caps, Top Embossed Caps, Knurl Embossed Chamfered Caps, Side Embossed Chamfered Caps, Deep Drawn Caps, Extra Deep Drawn Side dry offset printed caps etc

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's the oxidation method of positive pole on the surface of aluminum sheet?
Do chemical polishing again, oxidation time is about 40 – 90 minutes, after finishing all of these, you can conduct positive pole oxidation, choose sulfuric acid solution in normal situation, pretreatment is very important in the whole process, take stereo as negative pole, firstly, use the solution mixed of carbonate-bicarbonate and detergent to heat and clean its surface, pretreat the aluminum sheet, dyeing according to requirement after oxidation, then remove the oxide film with oxide film removal solution, place aluminum sheet on the positive pole, finally closing it in the boiling water for about 15 minutes.
Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
the surface should be kept clean to avoid the influence of oil contamination.
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 sprinkle the mix of Alkaline water,vinegar,washing powder and liquid detergent on the surface. And after a period of time, rub it with soft silk, after it being dry,sprinkle again and rub until it's clean.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
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:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:What are the colors of iron sheet and aluminum sheet?
they are both silver white.
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: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?
it depends on the size and requirement, we can use ultrasonic wave rolling welding to connect copper pipe and aluminum sheet.for example, solar energy radiator-fan contains connection of copper pipe and copper sheet, ultrasonic wave rolling welding equipment is used here.ultrasonic wave welding of metals is suitable for the welding of copper to copper, copper to aluminum and aluminum to aluminum.
