Production process and quality in a leading position in precision castings, with metal spectrometer, and other advanced detection equipment. A casting appearance defects Nomenclature and Classification 10 sticky sand on the casting surface, in whole or in part is covered with a metal (or metal oxide) with a mixture of sand (or paint) (or compound), or a layer of sand castings sintered density, resulting in a rough casting surface. Scarring on the casting surface 11, a metal containing sand or slag inclusions or flake or nodules. 12 sand on the casting surface, a layer of metal nodular or flakes. Between tumor sheet metal clip with a layer of sand and castings. 13 cold traps in the casting there is a gap or incomplete fusion pits, its edges are smooth handover.

Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. Cast iron platform, the biggest advantage of LFC casting machine without stems from the model, operating under the core and co-box castings, bring great benefits to the process, greatly improving production efficiency; but its biggest drawback is also derived from this, in fact, exist type look like liquid metal filling process becomes very complicated ordinary castings, which bring various defects cast iron platform, platform inspection of castings. In addition, the role of negative pressure casting process makes liquid metal filling complicated. Due to the disappearance of the liquid metal mold casting is by pyrolysis and gasification will look like, there is the appearance of liquid metal to replace the original position, after the formation of the casting solidification. In the forefront of the flow of liquid metal filling, there is a very complex physical and chemical reactions, heat transfer, mass transfer and momentum transfer process complex staggered. Steel casting process, the public Li Xin Casting Company E (certified), Hegang castings from Linyi Public Li Xin Machinery Limited. Linyi Public Li Xin Machinery Co., Ltd. (www.lyzlx.com) Shandong Linyi, casting leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
