Die casting process, the congregation Li Xin machinery, Xintai casting Li Xin Machinery Co., Ltd. is provided by Linyi public. Die casting process, the congregation Li Xin machinery, Xintai casting is Linyi Public Li Xin Machinery Co., Ltd. (www.lyzlx.com) launched this new upgrade, the above picture is only for reference, please call the contact or pictures on this page phone, obtain the latest information, contact: Peng. Linyi Public Li Xin Machinery Co., Ltd. located in Junan County Economic and Technological Development Zone, located in the southeast of Shandong Province Rusu junction, is the design, production, processing, marketing as one of modern science and technology enterprises, the use of advanced international cast today Process (EPC) a negative real casting process, production and more material high temperature, corrosion, abrasion, oxidation resistance alloy steel castings. The products are widely used in metallurgy, mining, chemicals, shipbuilding, paper, machinery, military and other industries. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. The company can design according to user needs, manufacturing a variety of standard and non-standard special foundry products. Casting a metal cast with a variety of the molded article obtained by the method, the liquid metal that is a good metallurgical by casting, injection, inhalation or other injection molding method in a pre-prepared mold, after cooling the like, obtained with a certain shape, size and properties of objects. Linyi Public Li Xin Machinery Co., Ltd. located in Junan County Economic and Technological Development Zone, located in the southeast of Shandong Province Rusu junction, is the design, production, processing, marketing as one of modern science and technology enterprises, the use of advanced international cast today Process (EPC) a negative real casting process, production and more material high temperature, corrosion, abrasion, oxidation resistance alloy steel castings. Liquid penetrant testing is used to check various openings on the surface of the casting defects, such as surface cracks, pinholes and other surface defects difficult to find the naked eye. Penetrant testing is commonly used in the coloring test, which is to have a high penetration ability colored (usually red) liquid (penetrant) soaked or sprayed onto the surface of the casting, penetrant flaw penetrate into the opening inside precision castings, quickly wipe the surface permeate layer, easy to dry and then display agent (also called an imaging agent) is sprayed onto the surface of the casting, will be left after penetrant defect in the opening sucked out, the display agent was stained, which can reflect defect shape, size and distribution. It should be noted that the accuracy of the heat-resistant steel castings, penetration testing material was seized along with increased surface roughness is reduced, the more light that is detected, the better the surface of alloy steel castings, grinding machine polished surface inspection highest accuracy casting, even detection of intergranular cracks. In addition to coloring detected, the fluorescent penetrant inspection is also commonly used liquid penetrant testing method, which need to be configured under UV light irradiation was observed, the detection sensitivity is higher than the coloring test.
