The Zinc-Aluminium Die Casting Alloys

3/18/2009 2:18:58 AM

New high performing zinc-aluminium ZA casting alloys (ZA-8, ZA-12, ZA-27) give superior mechanical properties which designers can apply utilizing die casting technology. In general the ZA alloys are stronger, harder and offer more creep resistance than standard zinc alloys and can be used where bearing properties are important. 　　Aluminium alloys with 0.5-0.9% Fe content have largely replaced 1350 EC alloy for making electrical circuits because the latter continuously suffered from gradual loosening at terminals, which led to overheating. This problem has been totally removed in new conductor alloys without sacrifice of conductivity. 　　To get economic benefit of weight advantage of aluminium wire should be capable of attaching securely to standard fixtures without special handling techniques. But EC wire on binding screw terminals tightened to a standard torque may become loose, when the wire heats due to being overloaded. The wire gets expanded more than the Cu-alloy fixture and creeps to relax the added stress. 　　On getting cool it contracts to a smaller dimension, whereby the area of contact is reduced and it permits oxide to form at interface. On a subsequent current overflow, the overheating increases which leads to further loosening of wire. EC wire annealed for adequate bend ability gets sub structurally loosened at 200°C and ultimately fails due to repetitions of these cycles. 　　The new alloys (800 series) of 0.5-0.9% Fe have much better microstructural stability and creep resistance and, therefore, they are not prone to these failures. 　　While annealed to the same ductility or bend ability, the high Fe alloys are double strong. This capability has been established by practical field use of many years in USA, Europe and South Africa after these alloys were introduced in 1968. 　　Better and latest alloys which not only provide high integrity to terminations but are suitable for magnet wire after normal hot annealing have been made after adding a third alloy to improve its performance examples are 0.5% Fe with 0.5% Co and 0.5% Fe with 0.2-0.4% Si. 　　Processing and microstructure: 　　In continuous casting a bar of 50cm2 is made at 16 m/min on a 2.5m diameter copper wheel. The quick solidification results in a 20 μm dendrite arm spacing and eutectic red cpacing of about 0.2 μm with a supersaturation of about 0.1% Fe. These very fine particles play a significant role in giving stability to substructure while being incapable of nucleating crystallization. 　　The presence of sub grains has been known in hot worked aluminiums but without quantitative determinations of the dimensions or the effects on properties. As the temperature rises from 200-450°C, the cold yield strength of the hot worked product decreases greatly from the strengthening made by 97.5% cold rolling. 　　As has been seen in many hot worked metals, the yield strength is inversely proportional to sub grain diameter. Because the temperature is less and strain rate is high in a given pass than those in the previous one, substructure “inherited” from i.e., carried forward from, the latter is altered by dislocations to the existing walls to raise their density and by formation of new walls to subdivide the sub grains lessening their size.

Die Casting in Aluminium Alloys

3/9/2009 11:07:31 PM

An aluminium alloy die casting system provides a die casting machine which has a gate for melted aluminium alloys passage, sets a flow rate of melted aluminium alloy in range of 5m/sec to 15m/sec and press injects melted alloy in cavity of die. By this system it is possible to get a weldable casting having no air. An aluminium auto part manufactured by above mentioned process is weldable and also dense in structure. The result is auto parts formed of die-cast products are produced on a large scale cost effectively. 　　Aluminium and aluminium alloys casting problems: 　　Aluminium castings have played significant role in development of aluminium industry since its inception in late 19th century. The first aluminium products were castings such as utensils and decorative parts which exploited the novelty and utilization of new discovery. Those early parts quickly expanded to meet the requirements of a wide range of engineering specifications. 　　Alloys development and analyzation of physical and mechanical features gave basis for product development through the decades which followed. Casting systems were processed to increase capabilities of foundries in new commercial and technical uses. The system of melted metal processing, solidification, and property development has been advanced to assist foundry man with means of cost effective and trustable production of components which regularly meet specific needs. 　　Nowadays aluminium alloy castings are manufactured in hundreds of ways by all commercial casting systems including green sand, dry sand, composite mould, plaster mould, investment casting permanent mould, gravity casting, low-pressure casting and pressure die casting. 　　Material constraints which previously limited the design engineers alloy choice once a casting process was selected are continuously being blurred by advancement in foundry techniques. Similarly process selection is also less restricted these days. Like the many alloys previously thought to be unusable in permanent moulds because of their casting features are in production by that very process. 　　Melting and metal treatment: Aluminium and aluminium alloys may be melted in various ways. Coreless and channel induction furnaces, crucible and open-hearth reverberatory furnaces fired by natural gas or fuel oil and electric resistance and electric radiation furnaces are all in routine use. The nature of furnace charge is as different and important as the choice of metal casting operations. The furnace charge may differ from pre-alloyed ingot of high quality to charge made up of low quality scrap. Even under best melting and melt holding situation melted aluminium is at risk to these types of degradation. 　　a) With time at temperature, adsorption of hydrogen results in increased hydrogen content. 　　b) With time at temperature, oxidation of melt occurs. 　　c) Transient elements featured by low vapor pressure and high reactivity are reduced. 　　Turbulence or agitation of melt and increased holding temperature, significantly increase the rate of hydrogen solution oxidation and transient element loss. The mechanical properties of aluminium alloys depend on casting soundness which is highly influenced by hydrogen porosity and entrapped non metallic inclusions. Aluminium casting and alloys and products manufactured by them are things of the future due to their cost effectiveness and lightweight.

Senior engineer Kevin Gay and Simon Tyler from the CAD department together oversaw the CMM installation at ARRK's Gloucester site. They conducted hours of successful trials over several months to ensure that the improved service was fully operational in time for its February 2002 launch. The parallel operation running at ARRK's site in Barcelona is led by Jésus Tejada and Alex Garcia, who both have considerable experience in the field of coordinate measuring machines. The Mistral machines are supported by the latest commercial PC-DMIS (dimensional measurement interface standard) software, which optimizes efficiency in working with parts and files submitted by customers. "Our customers have been telling us for some time that this is a service they really benefit from," said Gay, commenting on the success of the CMM to date. "Increasing CMM capacity will help them turn projects around more quickly and efficiently." Gay went on to note that developing its range of services to accord with changing customer needs has been part of ARRK Product Development Group's continuing focus on providing services that can make a difference to companies that need to complete projects quickly in order to remain competitive.

Chinese injection molding industry is poised for a good growth

11/24/2008 11:43:56 PM

China is the largest producer of injection molding machines in the world, ranking 1st in the world on both yield and consumption. Chinese injection molding machine industry is mainly distributed in Guangdong Jiangsu and Shandong provinces accounting for 88% of total enterprises in Chinese injection molding machine industry, as per a report by Research and Markets. Totally speaking, East China takes absolute advantages, of which enterprise quantity in Zhejiang province accounts for 61%, having increased by 14 enterprises over that in 2005. In 2000, market capacity of the whole industry realized RMB 4.598 bln, increasing to RMB 14.578 bln in 2006. Following it, per capita sales revenues have been increasing year after year, from RMB 198,114 in 2000 to RMB 462,012 in 2006 up by three times. Totally speaking, the market still kept a stable growth and gross profit margin is in decline; while profits are rapidly climbing. Undoubtedly, all of these have showed that China Injection Molding Machine Industry has been in a growing period. In the past few years, injection molding machine producers have got greatly improved on technology and management. However, compared with those in developed countries, injection molding machines in China still have a way to catch up on technology and varieties. In detail, there is still not little blank on such varieties as super-large or special precision injection molding machines; meanwhile, self-support rate of home-made injection molding machines for products processing is only about 45%; while for high-end products processing, most adopt imported injection molding machines. Totally speaking, research and manufacturing of injection molding machines cannot still satisfy demands brought by development of plastics industry in China. As for industrial machinery, presently most of other machinery processing enterprises have got poor benefits; while only injection molding machines have rapidly developed. And with sustaining and promising market, many enterprises which originally produced machine tools, textile machinery and power equipments, also started to produce injection molding machines. And meanwhile, newly-established injection molding machine producers are also rapidly growing; therefore, there mainly exist price war and discount war for ordinary injection molding machines. Since many automobile manufacturers and electronics & electrical appliances manufacturers congregates on 'Yangtze River Delta' region, now major consumption market of injection molding machines in China is spreading from the South to the North especially adjacent areas of Shanghai. Interestingly, Chinese processors offer products that are cheaper than many available alternatives, yet offer the same quality that Western customers deserve and expect. This is possible due to Extremely Low Labor Costs: Even though the injection molding industry uses a lot of expensive capital equipment, labor costs are still the largest single component of production costs. China's main cost advantage in mold making comes from savings in this area. Chinese wages for toolmakers are among the lowest in the world. In the US a tool maker earns over US$40000 pa, while his Chinese counterpart could be doing the same job for US$1000. The Chinese labor force is also well educated, thus keeping training costs low, and Chinese factories do not have the high healthcare and insurance costs of the US and Europe. Workers in capital-intensive factories in USA can be several times more productive than their Chinese counterparts. This is because U.S. plants have replaced many factory workers with complex flexible-automation and material-handling systems. This has reduced labor costs but raised the costs of capital and support systems. Chinese factories reverse this process, however, by taking capital out of the production process and reintroducing a greater role for labor. Parts are designed to be made, handled, and assembled manually. This reduces the total capital required by as much as one-third. So while output per worker may be lower in Chinese factories, the combination of lower wages and less capital typically raises the return on capital above U.S. factory levels. Low Factory Overhead Costs: Factory overhead costs for many Western injection mold manufacturers are high compared with certain foreign competitors. This is partly the result of firms operating at less than full capacity because of weak business conditions and intense foreign competition. Many Chinese firms operate 24 hours a day, 7 days a week, thus more fully utilizing their expensive machinery and making it relatively less costly (subject to adjustments for power saving schedules). Tooling on Cost Savings Give You More Options: A central benefit of Chinese tooling is that it allows the customer to make a profit using high-quality injection molding techniques at lower volumes than would often be required in the West. For example, customers using vacuum formings can often save a great deal of money by switching to China-based injection molding.
