Deburring Methods for Aluminum Strips

It’s easy for burrs to appear during precise process of aluminum products like aluminum strips. This results from insufficient press shock, lack in mold force and inappropriate mechanical cutting. With clients’ increasing requirements about aluminum strips for sale, more and more deburring methods are springing up as well. Here we make a collection for your reference. There are 13 methods all together, and we will introduce 4 here. The other 9 will be elaborated on in future articles.

1. Manual deburring
This is the most traditional and commonly used method in die-casting factories. Tools include manual or pneumatic files, sandpaper, belt conveyors, grinding heads etc.. Disadvantage of this method include expensive labor cost, low efficiency and difficulty in removing complex cross holes. However, the technical requirements for workers are not very high, and it’s suitable for aluminium alloy die casting with small burr and simple product structure.
2. Deburring of die
The burr removal is carried out by making a die and a punch press. Disadvantages include that it requires a certain cost for the production of stamping dies (rough and fine stamping dies), and it it may also need to make plastic dies. This method is suitable for die casting of aluminum strips with simpler parting surface. The efficiency and deburring effect are better than manual.
3. Grinding and deburring
This kind of deburring includes vibration, sand blasting, drum and so on. At present, it is widely used in die casting plants. The disadvantage is that the removal is not very complete, which may require follow-up manual treatment of residual burrs or other ways to deburr. This method is suitable for small aluminium finstock with large batches.
4. Deburring by freezing

Using cooling to make burrs brittle quickly, and then spraying projectiles to remove burrs, the price of equipment is about 2.3 million. This method is suitable for aluminium strips with small burr wall thickness and small volume.

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,...
