Aluminum Trim Coil Stock

Aluminum trim coil stock serves as raw material for casings trims wrapping windows, entry doors, ply gem shutters, accents shutters and ply gem stones etc. Owing to strong decorative function of aluminum trim coils, they are usually painted with hundreds of colors and designs to match various housing styles. There are solid colors, metallic colors, stone grains and wood grains.
Aluminum trim coil stock are usually of alloys 1100, 3003, 3004, 3105, 5006, 5052 and 3011 etc. Tempers for them include H16, H18, H24, H26 and H28. Their total thickness ranges between 0.05mm and 2mm, with a PE coating no less than 18 micro meters and PVDF 25 micro meters. In addition to PE and PVDF, other coating paints like epoxy, polyamide and polyurethane are also available. The surface treatment includes mill finish, coating and embossing.

Manufacturing process of aluminum trim coil stock includes decoiling, cleaning, coil-coating, IPQC, cooling, curing, exit-accumulating, recoiling and OQC. In the step of decoiling coil stocks are flattened by a decoiler. Then they are cleaned with chemical liquid, which guarantees complete cleanness of their surface. In the coating process a coil stock is coated with a given color or design. IPQC stands for input process quality control, which is carried out by the IPQC team who checks quality of the first rolls of coils. If the coils are confirmed as unqualified, the previous manufacturing steps must be stopped temporarily until relative problems are solved. During the whole manufacturing procedure, IPQC examines quality of aluminum trim coil stocks randomly from time to time, making sure there are no unqualified products going into the next process. After being coated with colors or designs, a coil stock is cooled and then cured. Then it comes to a recoiler through an exit-accumulator. After being rolled again, it goes through OQC (outgoing quality control).

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,...
