Aluminium Circle Sheets for Cookware Manufacturing Process

As an 11-year supplier of semi-processed aluminum products, we have built a huge database of clients all over the world. Many of our clients are cookware manufacturers. Some have regular orders every season. The cookware industry proves to be the largest consumer of aluminium circle sheets, which makes aluminium circle sheets for cookware a popular product in aluminum manufacturing industry. Here we’d like to introduce manufacturing process of the sheets.
aluminium circle sheets for cookware
After so many years of development, the manufacturing process for aluminium circle sheets has developed fully. Most workshops are equipped with fully advanced production lines. Such a line consists of a a decoiler, feeding machine, a punch press and a stacking machine. If you use aluminum sheets rather than rolls as raw materials for the circles, it’s unnecessary for you to prepare a decoiler which functions to flatten aluminum rolls. The sheet or flattened roll is fed into the punch press by the feeding machine. The punch press, the punch head size and precision of which have been set in advance, punches circles out of the left part of the sheet and then sways horizontally to the right for punching of the other part. The feeding machine then sends the sheet a little further so that the sheet waste gets out of the punching area which is taken up by the successive part of sheet. Aluminium circle sheets, on the other hand, are sent to the stacking machine. The sheets will be further checked and finished before being delivered out of the factory.
 There is a thin layer of oxide film on the surface of aluminium circle sheets for cookware. The film is only 0.00001mm thick. To make the circle sheets more durable, manufacturers usually have the sheets treated to improve thickness of the film. In this way, the cookware will be more resistant to corrosion.

What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
