YK aluminium hot rolled processing makes cap production good for deep drawing, and grade 99.7% high purity guaranteed the cosmetic cap surface bright, hardness is suitable.
Grade 1070 O temper aluminum cap strip is ideal for most perfume bottles and cosmetic bottles, which need shining and bright surface, such as cream jar, perfume bottle, screw top bottle, cosmetic cap etc.
Grade 1060 and 8011 aluminium plain strip, 1060 8011 aluminium lacquered strip is used for Injection vial seals.
Yikuo aluminium offer 1060 aluminum strip is used for injection vial seals. Because 1060 strip is easy to make and cheap price, in many countries 1060 strip is used for injection vial, which is still very common, Yikuo aluminum could offer plain aluminum strip, lacquered aluminum strip, coated aluminum strip in color of golden, white, red, blue, black etc, one sides color, both sides lacquered etc.
Yikuo aluminium produce 8011 aluminum strip injection vial seals, which is quite popular in China, used for pull-off aluminum caps.
1.Chemical Composition : Alloy type 8011 H16 According to EN573-3
2.Size and deviations from the size:
-Thickness tolerance -0+0.5mm
Width tolerance -0+0.5mm
Length tolerance -0+0.5mm
3.Surface of the sheets
The surface of the aluminum strip or coil for jar cap shall be oil-free, this is controlled by testing with clean natural cotton pads, dipped in 100% distilled water.
Droplets, spots caused by corrosion and burnt lubricant on the surface of the sheets not acceptable.
Minor scratches and staining not acceptable as well.
To make aluminum lamp cap, first stamping and then tapping into spiral shape, thinner materials and can undertake the pressure. Therefore, the 3004 lamp cap aluminum strip need to be with high mechanical strength and uniform microstructure and deep drawing property.
Currently Yikuo aluminum apply flat ingot hot rolling for producing blank holder with 3004-O aluminum alloy lamp cap strip. To make this 3004 O aluminum lamp cap strip, we have to control the composition of the material and cast rolling process, the high temperature uniformity of annealing and final annealing process, it have good deep drawing quality, enough strength, good formability.
1. Typical Products
5052 aluminum ring pull can lid strip: thickness: 0.22 – 0.5mm; width: 1280mm; 5052/5182: H19 alloy
2. Product Features
(1) Ring Pull stock generally adopts 5182 aluminum alloy processing, the Ring Pull Can Lid material generally use 5052 and 5182 aluminum alloys processed;
(2) flexible, stamping deformation is not easy to crack;
(3) small density, light weight, smooth surface, feel good;
(4) environmental protection is easy to recycle and reuse.
Compare with 8011 closure sheet, 3105 Aluminium screw cap strip has enough strength, so it is stronger enough to bear the gas pressure, so it is widely used for making screw cap for gas liquid bottle, such as soda water and carbonated wine.
We could treat 3105 Aluminium screw cap sheet with phosphoric acid chromated, and DOS coated, printed with different colors, on the basis of our plain sheet.
We control the materials composition, rolling temperature and time,and annealing temperature to product optimal materials to meet client’s performance needs, such as its opening capability and earing rate.
With our good flatness and squareness, we could prevent color gapping, unevenness or print misalignment during printing.
Surface type:
a. Plain mill finish aluminum strip
b. DOS oil lubricated finish
c. Chromated finish
d. One side golden/white/red/blue/black,etc other colored, other side protective lacquered
e. both sides clear/transparent lacquered
Test item: autoclave test, Hgcl2 test
Tensile strength: 130-155mpa
