Cause Cracks of aluminum alloy die castings are common in the process of die-casting aluminum alloy die-casting, so we only need to find out the cause of the cracks to find a solution, so what kind of die-cast aluminum alloy Huayin carries today Die-casting crack inventory and your cause, then avoid it and solve this problem! In the past seven years, the cracks of aluminum alloy die castings are mainly manifested in the following aspects: (1) Alloys with high iron content or low silicon content; (2) The content of harmful impurities in the alloy is too high, which reduces the plasticity of the alloy; (3) ) Aluminum-silicon alloy: Aluminum-silicon-copper alloy or copper-zinc alloy content is too high, magnesium alloy content is too high (4) The mold temperature of the specific core is too low; (5) The wall thickness of the casting changes quickly; (6) Put it in one In the long mold; (7) The vertex of discontinuous balance. Through the analysis of the reasons, the reasons for the cracks in the aluminum alloy die castings are obtained. There are seven points in summary. As long as these seven points are well controlled, die-casting production and aluminum alloy die-casting are carried out to avoid cracks in the parts. We were established in 1995. Up to now, it covers an area of 40,000 square meters and has more than 500 employees, including 5 senior engineers and 27 R&D personnel. We integrate mold design and manufacturing, aluminum alloy die-casting, precision machining, and surface spraying, providing one-stop supporting production services. The company has introduced 17 advanced 250-1650 tons cold chamber die-casting equipment from Japan and Taiwan, 32 CNC, one automatic spraying line, two American three-dimensional measuring instruments, one German material composition analyzer, and adopts advanced die-casting process. , Equipped with modern design and management software, and hired several senior engineers with many years of die-casting experience, which can develop and process all kinds of precision aluminum and zinc alloy die-casting parts with high quality and batch. The main products are lighting, automobiles, locomotives, motors, hardware, locks, furniture and other accessories. The main customers are Germany, Britain, Japan, Australia, and other well-known overseas manufacturers. The chairman of the company, Mr. Sun Gongyi, has been engaged in the hardware die-casting industry for more than 20 years. He has always insisted on customer-centricity and quality as life; upholding the concept of honest management and insisting on the management of high quality, accurate delivery and low cost. Goal; to ensure that products and services meet customer requirements. While continuously consolidating the domestic market, we are striving to open up overseas markets and have achieved brilliant performance, which has enabled the company's business to gradually move towards internationalization.
