Compatibility design of aerosol packaging

the new technology of empty can molding, which leads the trend of aerosol, is gradually on the stage of commercial production. In terms of speed and energy saving, companies such as sonic, singer+bienz, Alfons Haar and lanico have created their own leading positions; In terms of empty tank modeling, following the launch of Pascal can by Toyo Seikan, us can Europe and crown cork seal have become trendsetters with different new technologies. This paper attempts to track the latest equipment achievements and the molding technology of special-shaped aerosol cans for the reference of peers in the industry

in recent years, the new technology of aerosol packaging has gradually shifted from the basic function of studying the "compatibility" between packaging and contents to the direction of "faster, more energy-saving and more innovative". The sharp rise in world tinplate prices for two consecutive years has promoted the commercial production of new technologies

leaders who pursue faster and more energy-saving are tirelessly exploring new heights for transforming tension signals into electrical signals: Swiss welding machine manufacturer soudronic has launched 750cpm afb1075 high-speed aerosol tank welding machine, which is 3 ~ 5 times faster than general welding machines; The aerosol 2-out manufacturing line, the latest product developed by styner+bienz, a Swiss aerosol top cover equipment manufacturer, led the new mold concept and capping speed. They make the production speed of the top cover reach 500 covers per minute, and the hardness of the materials used can range from T52 to T65 (ASTM T2 to T5), so that the material thickness of the top cover can be saved by 10%. Alfons Haar company of Germany has developed the equipment cnc-af3-p25 (Fig. 1) for punching the bottom cover of the aerosol tank. The whole sheet is fed with curved edges. The four die punching speed is 832 caps/min, and the material utilization rate is 86.35%, while the speed of an ordinary straight edge single-mode punch is only 120 caps/min, and the material utilization rate is only 73.6%. At the same time, they first introduced the aerosol bottom cover made of DR (secondary rolling) material, so that the thickness of the general-purpose dia63 bottom cover can be reduced from 0.34mm (SR, primary rolling) to 0.24mm, while maintaining the same deformation and blasting performance. The tank cover with this technology has been used in batch in us can company. In the aspect of thinning the tank body materials so that the original strength of the composite materials can be fully utilized, the leader of the combination machine, German lanico company, launched the CF 389 empty tank forming machine for high-speed two-piece and three piece aerosol tanks. The design speed of the equipment is 500 cans/min. it is characterized by vertical in and out of the tank, six station combination, which can complete necking, flanging and capping at one time, and a pre necking station is reserved to match the lighter and thinner Dr tank body; Corus, Arcelor and rasselstein in Europe and their counterparts in the United States are actively studying two pieces of punching tin cans to seize the market share of two pieces of aluminum cans. After successfully solving DWI beverage cans, the next goal should be DRD aerosol cans

while equipment manufacturers try their best to improve production efficiency and save materials for users, empty can manufacturers and bottlers are still worried about how to attract customers' attention on the shelves and how to prevent the infringement of counterfeit products. Therefore, the special-shaped can molding technology with more novel shape, better visual effect, better hand feeling and stronger brand protection ability is the selling point that world-class empty can manufacturers and bottlers dream of

shaped tank forming technology has been developed for many years abroad and is becoming more and more mature. In China, some manufacturers are using imported equipment or self-developed equipment. Special shaped cans are divided into iron cans and aluminum cans from the material; The forming forms include bulging, bas relief, shrinking, stamping and closing, etc; Product applications include aluminum cans for beverages, steel cans for beverages, aluminum aerosol cans, tinplate aerosol cans and tinplate miscellaneous cans. Among them, the bulge technology has developed rapidly in less than 10 years. From Toyo Seikan, a Japanese company, took the lead in launching the "Pascal can" concept tank on the tinplate air freshener tank in 1996 and won the cannex Gold Award in 1997 and the cannex Silver Award in 2001, to us can Europe and crown cork seal at the international metal packaging exhibition in Duesseldorf, Germany, in 2003, they have continuously transformed their professionalism and efforts into the strong support that partners need most, and presented their charming products with different new technologies, It announced that the maturity and commercial production of this new bulge technology have become a reality

2003, although the price is 1.5 times that of ordinary products, the sales of us can Europe's special-shaped air freshener has exceeded 2million cans. Now, European fashionable women will put a can of quadrimex grenade air freshener produced by us can Europe in their bags. In the rapidly growing auto care market, the unique "WD-40" auto care agent launched by crown cork seal is the shining point. Crown cork seal has a huge "WD-40" car care agent market in the world. In order to maintain its brand position, the company decided to gradually start using new tank types from 2003, of which the 300000 ton biological composite material and additive manufacturing composite material project covers an area of 215 Mu to replace all the old tank types. This measure will bring a new atmosphere to the special-shaped aerosol tank

the author works in the largest manufacturer of three piece tinplate aerosol cans in Chinese Mainland. It is necessary to pay enough attention to and study such a hot spot in the industry. According to the investigation of about one year, the author roughly summarizes several forms of the bulging forming technology of special-shaped aerosol cans, and preliminarily discusses their advantages and disadvantages, hoping to give interested readers some reference. Before discussing the classification, it is necessary to browse the basic manufacturing process of ordinary three piece aerosol cans
