Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, the use of advanced international casting today (EPC) of a negative real casting process to produce more material casting temperature resistance corrosion castings, abrasion resistant castings, steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. Principles bed casting casting method chosen: a priority using sand casting, sand casting, mainly because of low cost compared to other casting methods, production process is simple, short production cycle. When the wet type can not meet the requirements to reconsider the use of clay sand dry sand, dry sand or other sand. Clay green sand casting casting weight from a few kilograms up to several tens of kilograms of steel castings density, while the production of dry clay castings can weigh hundreds of tons. 2 bed casting and casting methods should be adapted to the production volume. Low pressure casting, die casting, centrifugal casting and other casting methods, equipment and tooling is expensive, so only suitable for mass production. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, the use of advanced international casting today (EPC) of a negative real casting process to produce more material casting temperature resistance corrosion castings, abrasion resistant castings, steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. LFC liquid metal filling process, and metal flow front heat, mass and momentum transfer process. With the traditional sand casting steel castings compared to processing, resulting in the disappearance of molded type process more complex, not only directly related to the level of success and cast molding casting quality, but also the intrinsic quality of the casting has a critical influence. As we all know, cast iron platform, pulley casting defects since the basic source of liquid metal to solidify liquid filling a short time, in this short moment castings, mold cavity undergoing tremendous change, there is a heated look decomposition, the air gap, the liquid metal filling occurs between the forward advance of the appearance of its liquid metal filling frontier blocked the flow of liquid metal filling state of great disorder occurs, causing the metal filling vacuum flow bi-laws have a serious effect, gaseous pyrolysis product is discharged through the paint layer into the molding sand, the residual solid product of pyrolysis in the flow of the liquid metal filling the cavity is involved, the role of various impurities in the liquid metal by moving the negative pressure in the float becomes slow and some slack in the castings. Various physical and chemical reactions occurring phenomena are unable to see ordinary steel castings, castings become the "black box" .. Unlock the "black box.", Find the cause of defects produced castings, casting workers disappeared desire and longing coveted goal. The density of steel castings, steel castings Shaoyang, Chung Li Xin Casting Company E from Linyi Public Li Xin Machinery Limited. Linyi Public Li Xin Machinery Co., Ltd. (www.lyzlx.com) strong, credible, in Linyi, Shandong casting industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the congregation Li Xin casting company E and you work into the brilliant, for a better future!
