Near date, the Qirui automobile and the Czechoslovakia leopard Lu Huxin Cheng Li die casting products Joint venture announced that after in 2014 will complete may produce including the entire aluminum automobile body passenger vehicle’s upscale vehicle type. Now, substitutes the steel products with the aluminum material, production more light qualities, the festival can the automobile already is ultimately. Lifts at the line of Guangzhou auto show in November 22, in the Czechoslovakia leopard Lu Hu many patterns aluminum system new car collection shines: The brand-new update’s road tiger takes in all the beautiful scenery through uses the aluminum alloy material the complete bikes weight saving 450 kilograms; The Czechoslovakia leopard F-TYPE mode of motion runs the vehicle through to use the aluminum construction to cause its key component’s rigidity to compare its his part to be higher than 30%. since more than 100 years, automobile industry development and aluminum alloy application close related, but automotive industry prosperous, in impetus aluminum die castings consumption quantity growth.
The related research indicated that replaces the steel build car by the aluminum, may cause complete bikes weight saving 30%~40%, makes the engine to be possible to reduce weight 30%, makes the wheel hub to be possible to reduce weight 30%. In addition, aluminum nature radiator compared to same copper product light 20%~40%, but aluminum system automobile body compared to steeliness automobile body light above 40%. In the vehicles movement cycle, its own quality drops 1000kg every time, may reduce the fuel oil to consume 4800L, reduces the greenhouse gas to discharge 11.2 tons. This is a group of exciting data.
At present, aluminum in automobile amount used only Yu Gang and the cast iron, occupies third, but rises in the entire aluminum passenger vehicle’s amount used to second. The wheel hub is a calorization rate quickest example. In on century 80′s, the majority of passenger vehicles already started to use the aluminum alloy plastic injection wheel hub, compares with the ordinary steeliness wheel hub, it attracts shakes the strong tension to be good, corrosion resistance strong durable, can cause passenger vehicle’s comfortableness and the security can enhance. In addition, uses the aluminum alloy wheel hub’s environmental protection effect to be very obvious: The wheel hub quality reduces the 1kg,1L gasoline to be possible every time to go much 800m, but little uses the 1L gasoline, then may reduce 2.5 kg the carbon emissionses.
It can be said that the automobile reduction is one “eternal” the topic, the aluminum alloy follows an automobile industry group to walk, this phase of histories may trace established brand automobile De DionBouton which was published to 1898, it founded the automobile to use the aluminum the beginning. Hereafter, after no matter is bearing stand, the cylinder block, presented the plastic injection mold aluminum form. However, opened the automobile truly with the aluminum time prolog, when is Audi Corporation. Audi Corporation started from 1980 in Audi 80 and Audi on 100 uses the aluminum system vehicle door to start, it has never stopped the aluminum material application step, in 1994 Audi Corporation promoted global first entire aluminum automobile body passenger vehicle Audi A8, went on the market the only for 3 months in Germany, sold 2000, hereafter entire aluminum passenger vehicle Audi A8 started to carry on the batched production.
The so-called entire aluminum passenger vehicle is refers under the present engineering factor, the available aluminum alloy manufacture’s components calorized. Take Audi A8 as the example, its automobile body by the aluminum molding, the aluminum sheet and presses the casting to be made, own mass ratio steeliness automobile body light 40%, makes space frame (ASF) with the aluminum alloy extrusion material is similar to human body’s skeleton plastic injection molded parts is supporting spare parts and so on aluminum thin steel plate, but outside the automobile body the cover stamps out by the aluminum alloy thin steel plate becomes.
Actually, besides Audi, the coursing, the BMW, Ford, Lu Hu and so on international brand in abundance becomes the automobile with the aluminum cutting edge, causes the aluminum alloy has maintained in automobile industry amount used the steady growth the tendency. Statistics indicated that the 20th century 60′s, each automobile’s average uses the aluminum quantity is only 27.2kg; To the 90′s intermediate stages, this data rises 113kg, approximately composes automobile own quality 8%, in particular in the European and American date and so on developed industrial nation, the aluminum material continues in automotive industry application to increase, and has obtained the good economic efficiency and the social efficiency.
Our country automobile entered the swift growth with the plastic injection molding aluminum market the stage, some joint capital and the native place automobile brand has made the positive attempt, from Xi’an fertile Volvo the BIOM entire aluminum traveling bus, the entire aluminum public transportation passenger train which the Zhengzhou space passes, to the Shanghai populace’s aluminum alloy material quality electrically operated passenger vehicle, arrives again compared to the Asian entire aluminum automobile body electrically operated bus, because uses the aluminum alloy material massively, these vehicles’ reduction effect is very obvious, for example the automobile body electrically operated bus enough reduces 1.2 tons compared to Asian Quanlv compared with before the steeliness automobile body.
Although the aluminum cost is higher than the steel obviously, moreover the processing craft is more complex, but could not prevent the aluminum band steel development momentum throughout. At present, the automobile with the aluminum shape is mainly the casting, the forging, the molding and the plate, in which by casting plastic injection molding parts occupying compared to most remarkable, but looked from the application spot, the automobile body subdivides the market potential with the board. Statistics indicated that the automobile body approximately composes the automobile lumpy mass 30%, in the idling situation 70% oil consumptions use in the automobile body quality, the automobile body change approximately regarding vehicles’ fuel oil efficiency, the control stability, the crashworthiness are of great help lightly, this to a certain extent will stimulate without doubt the domestic aluminum Processing industry research and development automobile to use the molding, the plate enthusiasm.
The attractive market presses the plastic injection moldings aluminum business to make the big cake
Presently, although our country may produce while uses the aluminum alloy strap with the vehicle vehicle door and the engine cover, but the output are few and the quality is unstable. But in the automobile body with the aluminum strap production aspect, our country has been at the vacancy condition, until now had still not completed has the global advanced level modernized production line. It is known that this awkward situation is broken hopefully, China was prosperous 3,000,000 ton aluminum rolling material project which prepared for construction is precisely loyally aims at the automobile body to use the aluminum strap market.
Expert expression: “in the future, the automobile lightweight will impel the aluminum thin plastic injection mould steel plate, the cut deal in China’s widespread application, China loyal prosperous automobile body aluminum strap service to bring the rich profit repayment for it, regardless of because will be the domestic demand, the overseas export, its market absorption capacity and the income will be attractive, once the domestic product can substitute the import, not only will reduce the automobile enterprise’s production cost greatly, moreover other countries will set up the trade protectionism in view of this product the possibility to be extremely low.”
Our country “the short board” is mainly lacks in the automobile body aluminum strap production aspect has the high-tech level finishing equipment, because the automobile body aluminum strap has each kind of extremely strict quality requirement to its surface condition, current only then country enterprises and so on US, Germany, Japan, France have the productivity.plastic injection mouldings The aluminum plate mainly uses in the enclosed body and the heat interchanger system, the van vehicle compartment, the luxurious bus outer covering and the floor, the light car automobile body, the heavy card fuel tank and the air drum, the trunk lip, the engine hood panel, the passenger vehicle and the passenger train vehicle door and so on. The development facility estimated according to the present our country automobile industry’s development momentum that our country automobile industrial used aluminum strap demand amounts to 55 ~ 600,000 tons hopefully to 2015. But in last year, the whole world plastic mold injection automobile body aluminum sheet demand has amounted to 250,000 tons.
