  • IJESRTJOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY Shell Mold Casting Manufacture of Complex Parts with Thin Sections
    2020
    Co-Authors: Mazhar Iqbal, Sushil Patel, Ganesh Vidyarthee
    Abstract:

    Shell Mold Casting or Shell Molding is a metal Casting process in manufacturing industry in which the Mold is a thin hardened Shell of sand and thermosetting resin binder backed up by some other material. The internal surface of the Shell Mold is very smooth and rigid. This allows for an easy flow of the liquid metal through the Mold cavity during the pouring of the Casting, giving Castings a very good surface finish. Shell Mold Casting enables the manufacture of complex parts with thin sections and smaller projections than green sand Mold Casting. Manufacturing with the Shell Mold process also imparts high dimensional accuracy. Tolerances of .010 inches (.25mm) are possible. Further machining is usually unnecessary when Casting by this process. Shell Mold Casting is particularly suitable for steel Castings under 20 lbs; however almost any metal that can be cast in sand can be cast with Shell Molding process. Also much larger parts have been manufactured with Shell Molding. Typical parts manufactured in industry using the Shell Mold Casting process include cylinder heads, gears, bushings, connecting rods, camshafts and valve bodies.

  • Vessel phantom fabrication using rapid prototyping technique for investigating thermal dosage profile in HIFU surgery
    Rapid Prototyping Journal, 2010
    Co-Authors: Cho-pei Jiang
    Abstract:

    Purpose – The purpose of this paper is to propose a method for fabricating tumor vessel phantom and then investigate the thermal dosage profile caused by high‐intensity‐focused ultrasound (HIFU) surgery.Design/methodology/approach – In this paper, a thermal sensitive powder has been added to silicon‐based gel as a vessel phantom raw material for displaying the thermal dosage profile caused by HIFU. A fused deposition modeling system was used for fabricating the Shell Casting Mold and the vessel arbor Mold. The arbor prototype, made of wax, was solidified in the cavity of vessel arbor Mold. The vessel phantom object embedded with the arbor prototype was created in the Shell Mold Casting process. The vessel phantom was obtained by immersing the vessel phantom object into hot water (65°C) for melting the vessel arbor prototype. A HIFU experiment has been conducted for verifying the feasibility of displaying the thermal dosage profile of the fabricated vessel phantom. The HIFU experimental parameters includin...

  • Investigation on Occlusion Effect of Tumor Vessel in HIFU Surgery
    2009 2nd International Conference on Biomedical Engineering and Informatics, 2009
    Co-Authors: Cho-pei Jiang
    Abstract:

    In this study, a thermal sensitive powder has been added to silicon based gel as raw material of vessel phantom for displaying the thermal dosage profile caused by high intensity focused ultrasound. A fused deposition modeling system has been used for fabricating the Shell Casting Mold and the vessel arbor Mold. The arbor prototype, made of wax, is solidified in the cavity of vessel arbor Mold. The vessel phantom object embedded with the arbor prototype is created in the Shell Mold Casting process. The vessel phantom is obtained by immersing the vessel phantom object into hot water (65c' C) for melting the vessel arbor prototype. A high intensity focused ultrasound (HIFU) experiment is conducted for verifying the feasibility of displaying the thermal dosage profile of the fabricated vessel phantom. The HIFU experimental parameters including driving power ofHIFU transducer, ultrasound exposure duration and volume flow rate are used for investigating the thermal dosage variation by the perfusion of vessel phantom. The properties of fabricated mimicking phantom agree well with those of human tissue. The experimental results show that the proposed method can fabricate the Y-type vessel phantom. The proposed method has been proved as a promising fabrication process in fabricating the vessel phantom and it displays the thermal dosage profile in HIFU experiment.

  • Numerical Modeling of Thermal Stress State of "Shell Mold-Casting" System with Phase Change when Inverstment Casting
    Materials Science Forum, 2019
    Co-Authors: V.i. Odinokov, A.v. Sviridov, E.a. Dmitriev
    Abstract:

    This work summarizes and generalizes the results of long term researches of mathematic modeling of stress-strain state (SSS) of Shell Molds (SM) considering their morphological structure and types of hydromechanical and temperature impacts on them. A problem for determination of SSS of multilayer SM with internal porous layer during filling this Mold with melt and Mold hardening considering the phase changes was set and solved. At the same time the calculation methodology described in the early works of authors, namely constitutive equation system, numerical method, numerical scheme and solution algorithm was used. The results of numerical solution of the problem, namely diagrams of stresses arising in the SM during Casting hardening are given here.
