Aluminum Window Seal Strip

Aluminum window seal strip plays an important part in window installation. It’s made of silicon gel rather than aluminum strips. As an connection between glass and frames, it can be applied to common, suspended and folding windows. The purpose to use aluminum window seal strip is to protect a house against water, bugs, noise, dust cold air and save energy while air-conditioning systems are in operation. There are various shapes and types of aluminum window seal strips to meet installation requirements for different window frames. Customization of colors and specifications is available with most manufacturers.

Not a few manufacturers supply aluminum window seal strips made of low quality materials. The most representative method is to replace top quality plasticizer with waste engine oil. Excellent aluminum window seal strips demonstrate smooth and flat surface, high elongation, good flexibility, satisfying temperature resistance and perfect ageing stability. To guarantee excellent installation effect, clients are advised to take the follow steps before making a purchasing decision. First, check whether the seal strip smells unpleasant or not. Top quality strips have slight rather than strong strange smell. Second, entwine a strip around a solid profile, leave it in environment of high temperature (under the sunshine, for instance) and examine whether the contacting surface with the profile becomes stained or changes color, and whether dust on the strip surface turns yellower (the color of cheap engine oil). Third, skip cheap seal strips with dull surface, which proves to be of low quality. Fourth, check whether the weight of a pack of aluminum window seal strips are reasonable. Some strips have been mixed with coarse whiting by manufacturers who wish to increase profit by heavier weight. This kind of strips will produce a kind of white powder on surface after being stretched several times by your hands.

Slitting of 1mm 2mm 4mm aluminium strip

图片
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 ...

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 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,...
