Fabrication of Ceramic Moulds Using Recycled Shell Powder and Sand with Geopolymer Technology in Investment Casting
applied sciences Article Fabrication of Ceramic Moulds Using Recycled Shell Powder and Sand with Geopolymer Technology in Investment Casting Wei-Hao Lee, Yi-Fong Wu, Yung-Chin Ding and Ta-Wui Cheng * Institute of Mineral Resources Engineering, National Taipei University of Technology, Taipei 10608, Taiwan; [email protected] (W.-H.L.); [email protected] (Y.-F.W.); [email protected] (Y.-C.D.) * Correspondence: [email protected] Received: 1 June 2020; Accepted: 29 June 2020; Published: 1 July 2020 Abstract: Lost-wax casting, also called precision casting, is the process of casting a duplicate metal sculpture cast an original sculpture. The ceramic shell mould used in lost-wax casting usually consists of several layers formed with fine zircon and granular mullite particles using silica gel as a binder. However, it is a complicated and time-consuming process. Large amounts of waste moulds that need to be disposed and recycled become an environmental concern. In this study, waste shell sand from the recycled mould and calcium carbonate/metakaolin were used as raw materials to prepare geopolymer slurry and coating. The influence of mixing ratio and the SiO2/K2O modulus of the alkali solution on the setting time and green/fired strength were evaluated. Ceramic shells with one to four layers of geopolymer slurry and waste sand sprinkling were fabricated and tested for their permeability and green/fired strength. It was found that geopolymer shells had higher green/fired strength and better permeability than the original zircon/mullite shell. For foundry practice, metal casts were fabricated using recycled ceramic shell moulds with one to four layers of geopolymer coating.

Study of Ceramic Slurries for Investment Casting with Ice Patterns
Study of Ceramic Slurries for Investment Casting with Ice Patterns Qingbin Liu, Ming C. Leu Department of Mechanical and Aerospace Engineering University of Missouri – Rolla, Rolla, MO 65409 Harish Jose, Von L. Richards Department of Materials Science and Engineering University of Missouri – Rolla, Rolla, MO 65409 ABSTRACT Ice patterns generated by rapid freeze prototyping or a molding process can be used to make ceramic investment molds for metal castings. Due to the use of ice, the ceramic slurries must be poured around the pattern and cured at sub-freezing temperatures. Success of this process depends greatly on the mold strength after the gelation of the slurries. This paper describes the experimental results of the mold strength after the gelation of the slurries under different compositions. The parameters considered include mixing time, alumino-silicate vs. fused silica ratio, volume of binder, and volume of catalyst. The strength of the gelled slurries is examined by breaking test bars on a four-point bending apparatus. Weibull modulus for each trial is calculated based on the breaking strength from four-point bend tests. Analysis of variance for breaking strength and Weibull analysis is performed to evaluate the significance of the effect of each parameter. The casting of a bolt is used to demonstrate that metal castings of complex geometry can be fabricated using investment casting with ice patterns. 1. Introduction Every foundry has shell cracking problems in investment casting as a result of mechanical stress. To avoid the shell cracking problems, the investment casting process and the materials used must be strictly controlled. New approaches to improve the performance of investment casting process are constantly being sought.

E-mail address: [email protected] Received 30.06.2011; accepted in revised form 27.07.2011 Abstract Ceramic casting moulds strength is an important factor, which influences the quality and properties of castings being produced by the investment casting method. It is especially important during mould pouring with liquid metal. Studies allowing determining the casting mould strength at high temperatures, that means at the ones at which the moulds are poured, are not numerous. None generally accepted (normalized) method for the assessment of such strength exists in practice. The new method of the ceramic moulds tensile strength investigation at high temperatures is described in the paper. Tests were performed at temperatures from 100 to 1100oC. The ceramic moulding sand was prepared of modern materials: colloidal silica – being a binder – and highly refractory ceramic materials. Keywords: Melted models, Ceramic forms, Strength, Colloid silicate 1. Introduction • pouring with liquid metal, the most often in a vacuum furnace, • The technology of casting production by means of investment casting knocking out and cleaning. casting has been already known for some centuries.

Even if the galvanic electrodeposition is certainly a mature technology, new concepts, novel applications, environmental legislation and the new material requirements for next-generation devices make the scientific research in this field still very active. This review focuses mostly at the decorative and wearable applications, and aims to create a bridge between the past knowledge and the future direction that this process, i.e., electrodeposition, is taking.
