Applied Research Of Light-Weighting Technique For Aluminum Easy Open Can

From 60's of the 20th century, the aluminum easy open can was putted into market, it was warmly welcome by the people as its too many advantages such as , light in weight, big in volume per unit ,easy to open and carryover and long retention period etc. Its usage and quantity are expanding from day to day. It is estimated, the total global used quantities could be reached to 240 billion cans in 2000.Such development tendency of can's usage stimulates its technique research and development.Light-weighting of aluminum easy open can is a technique which is based on reaching the product quality standard, keeping the used performance and meeting the demands of customer, by means of a series of technical method such as new technique, material and mould etc., reducing the consume of material during the process of can making, in order to lower cost and higher economics.Upon author's long distance experience in producing aluminum easy open can, he had studied and researched deeply many kind of easy open cans in the worlds, analyzed the technique of key several production program of can making and solved a series of key technical problems during the process of light-weighting such as, aluminum raw material, can profile design, press technique and mould design etc.After carrying out light-weighting, the used aluminum raw material thickness of easy open can's body could be thinned from 0.325mm to 0.285mm, the weight of gram per can could be reduced from 13.625G to 11.948G, its economic benefit could be more big obviously.
