Developing Prospects of Aluminum Closure Sheet in China

Aluminum closure sheet is typically used for bottle capping around the world. In China there are two types of raw materials for bottle caps: plastics and aluminum. Although plastics is taking up a larger market share, aluminum has a promising developing prospects in China.
It’s used to be said that the biggest advantage of aluminum closure sheet over plastics lies in its excellent property for anti-fake design. As a matter of fact, however, plastic caps are usually featured by more complicated anti-fake structures. They have diversely processed surface, strong three-dimensional effect, novel appearance as well as good back-flow prevention. In spite of all the advantages above, several intrinsic weaknesses seem to be unsolvable. Owing to the fact that glass bottles from hot forming process demonstrate big errors in neck size, it’s difficult for plastic caps to seal the bottles completely. Besides, plastic powder from ultrasonic welding pollutes the bottled contents frequently, which remains to be solved. What’s more, some manufacturers even mix raw materials with cheap plastics. That makes the pollution even more serious.
In comparison with plastics, aluminum closure sheet has better properties, lower cost, less pollutant and higher recyclable value. Although aluminum caps are generally simple-shaped, they are delicately designed and printed. Costing only a half of plastic caps, they have no pollution at all. Made of a metal well-known for its popularity at reclamation depots, they boast higher recyclable value than plastics. Further more, bottles sealed by aluminum caps can be placed in containers of high temperature for sterilizing. Currently China has nearly 200 cap manufacturers supplying about 9 billion pieces of aluminum caps of hundreds of types. Aluminum caps have strict requirement about strength, elongation rate and size error of aluminum enclosure sheets, which forces manufacturers to adopt aluminum sheets of premium quality.

Slitting of 1mm 2mm 4mm aluminium strip

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 slitting. The loop

Diamond Embossed Aluminum Sheet Application

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 purposes as tread pla

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, clients requi
