Lost-foam casting
Lost-foam casting. Lost-foam casting ( LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.In lost foam casting, the preforms of the parts to be cast are molded in expandable polystyrene or special expandable copolymers. Complex shapes can be formed by gluing moldings together. The preforms are assembled into a cluster around a sprue and coated with a refractory paint. The cluster is invested in dry sand in a simple molding Lost foam casting ScienceDirect

Metallurgical Aspects of Aluminum Lost Foam Automotive Castings
Metallurgical aspects of the lost foam aluminum casting process used for production of 4-cylinder engine blocks and cylinder heads are presented. Results represent a high-volume lost foam foundry producing a common alloy, AA 319.0-T5, for all components. The influence of proper chemistry selection, degassing of liquid aluminumLost Foam offers an environmentally friendly process with the added advantage of more accurate casting. Foam patterns are created from polystyrene beads. The beads start as hard granules, very similar in size and shape to sand granules. The beads are expanded, allowed to stabilize and then molded into the desired shape.The Lost Foam Process :: Vulcan Engineering Co.

Investment casting is, however, a more expensive and labor intensive process. "Full mold casting", or "Evaporative pattern casting" is a newly developing process based on a pattern formed of light plastic foam instead of wax. Most commonly, the pattern is made of expanded-bead polystyrene. Cores are not used.And since the sand in the lost foam casting process is not mixed with any binders, sand recovery is faster, easier and cleaner. Reusing and recycling sand cuts material costs as well. The accuracy of lost foam casting means faulty products are not being tossed out due to the increased likelihood of errors found in the green sand casting process. 6.Lost Foam Casting: 6 Benefits for Your Next Project

Degradation Mechanism of Expanded Polystyrene (EPS) Foam in Lost Foam
fabrication of near-net shape metal castings using expanded polystyrene (EPS) foam patterns that are coated with refractory slurry and is effective for producing aluminum or iron castings of complicated geometry. However, the LFC process can produce considerable amount of scrap due to casting defects. Removing the EPS thermal decomposition is formed to be the casting. Classic lost foam casting processes is shown in Figure 1.

Metals Free Full-Text The Impact of Process Factors on MDPI
The lost foam casting (LFC) process has been known globally since 1958 when Shroyer published his patent [], where he described the use of a Styrofoam pattern reflecting the shape of the casting.The method is also referred to as “Full Mold”, which emphasizes pouring a mold without removing the casting, which is subject to Lost Foam Casting. Lost foam casting is a process used to create complex metal pieces and parts in which molten metal evaporates a foam mold being held still with sand. The process starts with a polystyrene foam as the mold material which can be carved, machined from a foam block, or created using a process similar to injection molding.Lost Foam Casting The Federal Group USA
