5052 5182 5082 H19 Aluminum Coil for Ring Pull End

Aluminum Alloy sot two piece cans is composed of two parts and tank and lid, referred to as the "two piece can". "Two pieces of cans" has the unique advantages of light weight, not easy to break, the appearance of trademark printing bright and occupy a place in the packaging industry.



In order to make it easier for consumers to open canned food, how to open cans has long been a topic for the manufacturers, food processing plants and inventors. In the late eighteenth Century, the open tank method began to be useful as a loop puller with an ingenious design, but the test found that on the one hand it was too expensive, and on the other hand it was unreliable. Through continuous study, in 1959 the United States of Ohio DRT company's engineers use the tank cover itself with metal rivet material forming a riveting, then a ring, with suitable notches and become complete easy. The invention of the metal container after a long one hundred and fifty years of development have made the historical breakthrough, laid a solid foundation for cans and beverage industry development. Then in 1964 the United States first by crimping tab, then the lid design has been further improved.

In the open the lid, pull gently upward lift, when the pull torque generated cover breaking rivets at the notch, and the notch along the track in advance opened a mouth. So it is easy to get in the tank without any additional food, can opener. After the advent of this product, the first batch of cans packed 50 thousand cans of beer into the market, success in one fell swoop. Quickly swept the world. The seemingly simple but easy integration of advanced technologies in metallurgy, chemical industry, machinery, electronics and many other industries has become a microcosm of the deep processing of aluminum in the body.

Performance requirements of 5052 5182 5082 H19 aluminum coil for ring pull end

The raw material is used 5052 5182 5082 H19 aluminum coil for ring pull end, cover material with good and is 50525182 H19, the alloy material ring model is 5082 5182 H19 series. Different manufacturers on the basis of the technical equipment itself, easy ribs and technical level, and different cover materials specification selection of width and thickness of different.
 
Requirements  properties of 5052 5182 5082 H19 aluminum coil for ring pull end:
 
1) The thickness of the material to be provided must be uniform. Tolerance is at + 0.005mm.

2) The purity, strength (tensile and anti yield) of metals must always be consistent.
 
3) In order to prevent the contact between aluminum alloy metal and food, the surface of aluminum must be coated with double sides. This is also to prevent excessive wear and tear of the mold measures.
 
4) In order to prevent the quality defects caused by aluminum extrusion and deformation during the stamping process, a layer of lubricant should be applied on aluminum.
