The replicast CS (Ceramic Shell) process

Effects of vibration frequency on microstructure, mechanical properties, and fracture behavior of A356 aluminum alloy obtained by expendable pattern shell casting

“…The expendable pattern shell casting process is a compound precision casting technology and suitable for producing complicated and thin-walled aluminum alloy precision castings [6][7][8], which combines the foam pattern preparation of the lost foam casting (LFC) and thin shell precision fabrication of the investment casting. There are many advantages for this compound casting process, such as flexible design and low cost of foam pattern, high precision of investment casting, and good forming ability.…”

Study on the surface roughness of ceramic shells and castings in the ceramic shell casting process based on expandable pattern

“…Since Ashton et al (1984) developed the ceramic shell casting process based on the foam pattern (Replicast CS process) at 1984, researchers and precise casting production enterprises have already recognized its advantages over lost foam casting and lost wax casting, and have mainly employed it as a solution to carburization of low-carbon steel castings produced in the lost foam casting process. Wang et al (2007) and Wen et al (2009) reported that with the rapid development of aerospace and automotive industry, the demand for complicated and thin-walled aluminium and magnesium alloy precision castings increases markedly due to their lightweight and high strength-to-weight ratio.…”

Combined effects of mechanical vibration and wall thickness on microstructure and mechanical properties of A356 aluminum alloy produced by expendable pattern shell casting

“…It was first proposed by Ashton, named Replicast CS process [16]. This compound casting process adopts the foam pattern preparation of the LFC method and thin shell precision fabrication of the investment casting method.…”
