Coating processes of vinyl coated aluminum coil stock

Color coated aluminum coil is an aluminum product that is currently used more widely. And one of the most frequently applied one is vinyl coated aluminum coil stock, widely used in machinery and home decoration. Its coating processes include brushing, scrape coating and dip coating.

Brushing is the earliest, simplest and most traditional manual coating method for vinyl coated aluminum coil stock. It is easy to operate and flexible. It can be applied to items of any shape, and it’s suitable for all kinds of coatings except for paint with fast drying and poor leveling. The brushing method allows the coating to penetrate the pores of the metal surface and enhance the adhesion of the coating to the metal. Disadvantages are high labor intensity, low work efficiency and poor coating appearance.
Dip coating is also a traditional coating method for vinyl coated aluminum coil stock. The aluminum coil stock is immersed in the bath containing the coating, and then taken out, during which the excess paint drips back into the bath or is removed mechanically. The method has large solvent loss and huge air pollution. It is not suitable for volatile coatings, and is generally used for equipment or workpieces with complicated structures.
The three coating methods mentioned above for vinyl coated aluminum coil stock must be selected carefully in practise in order to obtain the best coating effect.

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 ...

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,...
