Metal Casting Technologies : September 2007
WHO'S WHO OF METALS -- ANNUAL 2007/8 51 replacement of casting namely in the lost foam and investment casting. With such price competition, Magmasoft sees opportunities for the industry in trying to capture more lucrative markets like aerospace or sports performance cars. However, they noted, "Future for casting industries is limited as automotive markets still capture about 70 per cent of the market. We'll continue to see local companies shifting their operations to other neighbouring countries so they can price themselves better and be close to the automotive assembly centres like China and Thailand." TAIWAN By Paula Wallace, Associate Editor MCT Taiwan's metal casting industry is quite well established in comparison to the less developed Asian economies, with Japan and America being the recipients of most of its cast products in the form of automotive and golf club head components. Jiunn-Lin Yeh works in the Casting Technology Section of the Metal Industries R&D Centre in Taiwan. He told MCT magazine that around 30 per cent of cast metal products in Taiwan are used for the domestic market. The major foundries in the region include China Metal Products (cast iron), Fu Sheng Group (golf club head components) and Lioho Machine Works (car components). Jiunn-Lin Yeh suggested the largest car components produced in Taiwan are aluminum wheels. Other aluminium cast products include automobile and motorcycle parts, and electrical appliance parts. Gray iron castings include machine tool beds and parts, automobile parts, industry machinery such as bolts and nuts, forming machine and injection forming machine. Ductile iron castings include centrifugal pipes for running water, oil pressure machine parts, cylinder blocks, exhaust manifolds and crankshafts for automobiles. Steel castings include mineral machine parts, container corner fittings and valves. Investment castings include golf club heads, valves, artwork, aerospace and general industry parts. Magnesium castings include housing of 3C, automobile and motorcycle parts. Copper castings include artwork, valves, faucets, plumbing and sanitary fixtures/fittings and ship accessories. Zinc castings include hardware tools, automobile parts, motorcycle parts, bathroom and kitchen fittings. VIETNAM By Paula Wallace, Associate Editor MCT Famous for its abundant natural resources, skilled and hard-working work force, together with the government's policies to open market economy and commitments towards more transparent legal system, Vietnam is emerging as a new competitive manufacturing country, of which foundry and mechanical industries are no exception. There are no official statistics on the metal casting industries in Vietnam at present. The Vietnam Foundry and Metallurgy Science and Technology Association (VFMSTA) - http://www. castingarea.com/societies/vietnamfometa.htm - is currently working with the Vietnamese government to conduct an industry-wide survey over the next 12 months. The unofficial volume of product coming out of Vietnamese foundries each year is between 400,000 to 500,000 tonnes, said May Casting's managing director, Le Thanh Thao. "There are many small family owned foundries, with production capacity of less than 100 tonnes per month," said Le Thanh Thao. "There are about 20 foundries of bigger size with monthly production capacity ranging from 100 tonnes to 500 tonnes." May Casting, located in Hanoi, is an agent for Inductotherm in the region and supplies and services foundries with materials and equipment. The company was able to provide MCT magazine with some insight into the sand-moulding ferrous foundry industry. The biggest influence in the past 12 months on the ferrous foundry industry was the raw material price, since most of its consumables (ferro alloy mould material) are imported. "Steel scrap and pig iron is not enough and of low quality and was affected by the world steel price and demand from local steel billet mills," said Le Thanh Thao. * Including thixomolding process.
