SMEMACH Casting Process Portfolio: Sand, Shell, Lost-Foam & ADI Castings for Steel, Iron and Aluminum

Sand casting in the foundry field has a long history, casting production is also quite large;Shandong Province is currently China's casting film sand manufacturers are more concentrated areas, SMEMACH professional film sand casting parts has been more than 15 years of history, the basic technology has been very mature, the current use of film sand casting production of precision steel castings face some of the problems that need to be solved, such as sticky sand (scars), cold barriers, porosity, etc., how to solve these problems remain to be further explored and solved! How to solve these problems remains to be further explored and solved.

Lost foam casting process​ is an advanced and versatile metal casting process that combines precision and efficiency to create high-quality components. This method is particularly beneficial for producing parts with intricate geometries that would be challenging or cost-prohibitive with traditional casting methods. This process uses foam patterns coated with a refractory material to produce intricate metal parts, making it ideal for industries that require complex designs, such as automotive, aerospace, and industrial machinery. Precision Lost Foam Casting is an improved process of Lost Foam technology. It uses a shell processing technology to make the surface finish of the cast product more delicate and meet the needs of customers. At Sinostar MACH, we specialize in delivering precision casting solutions. Let's start with Lost Foam Casting technology.

Lost-wax casting (or investment casting) is an ancient metal-forming technique where a detailed wax model is encased in a mold (usually plaster/investment), the wax is melted out (lost), and molten metal (gold, silver, bronze) is poured into the cavity to create an exact replica, ideal for intricate jewelry, art, and precision industrial parts like aerospace components. The process involves creating the wax model, building the mold, burning out the wax in a kiln, pouring the metal, and finishing the final piece.

Vacuum die casting is a method for manufacturing high volumes of identical precision parts, usually with complex geometries. It is very similar to traditional die casting, but with an added vacuum system that removes almost all of the air and other gasses from the die before the molten metal is introduced. This improves product quality overall and, in particular, reduces porosity,lower porosity leads to more consistent mechanical behavior. Sinostar MACH combines the factory's many years of experience to discuss the importance, working principle, application and advantages of vacuum die casting process in this article.
