Investment Casting Process

Abstract: The Investment casting (IC) method is now used to make all precision components in the medical, hydropower, defence, car, and other sectors. IC has a wide range of applications and is well-known for its ability to make complex near-net form items with great dimensional precision and surface polish. Various scholars are making ongoing efforts to investigate the topic of investment casting. This publication offers a comprehensive survey of the studies in this vast topic. It emphasises improvements in the earliest stages of the investment casting process. It focuses on pattern creation improvements, mould composition, casting materials, and typical flaws, as well as preventative actions. Keywords: Investment casting, Pattern modelling, Mould, TiAl alloys, defects

Abstract The article presents an analysis of the applicability of the Replicast CS process as an alternative to the investment casting process, considered in terms of the dimensional accuracy of castings. Ceramic shell moulds were based on the Ekosil binder and a wide range of ceramic materials, such as crystalline quartz, fused silica, aluminosilicates and zirconium silicate. The linear dimensions were measured with a Zeiss UMC 550 machine that allowed reducing to minimum the measurement uncertainty

Metal Matrix Composite Material

This paper presents the design and simulation on investment casting mold for metal matrix composite material. The study was investigating the design parameters for the casting mold and simulated the temperature and pressure on the mold. Compressor impeller selected as the product of the study. Among the various types of casting techniques, investment casting process is the most suitable process to produce the compressor impeller. The alternative design of casting mold of investment casting was generated using CAD software. Concept scoring was prepared to select the suitable design for the investment casting process. Material selection of compressor is Aluminum Silicon Carbide. Stainless steel AISI H13 is selected as the material for the mold. The parameter for the mold design is included branch, gating, sprue and runner. The analysis was presented to the mold by using ANSYS simulation tool to determine the temperature and pressure of the mold. In addition, three case studies were presented and compared the static pressure in different velocity and temperature of the mold design. The result showed the runner and the branch size were important to produce the molten metal flow into the mold pattern. As a result, the design of investment casting mold was proposed.
