Lost Foam Casting, pressurized casting, solidification, mechanical properties. Abstract. The paper presents the result of investigation on aluminum-silicon (LM6) alloy cast using pressurized lost foam casting process. The study investigated the effect of pressure and sand size on hardness and roughness of the casting produced. Air pressure of 1, 2, 3 and 4 bars was applied on the solidifying alloy poured in mould of sand sized 40-60(AFS). The roughness and hardness of the casting was measured using Hobson (Surtronic 3+) and Vickers hardness testing machine respectively and reported in the average of ten readings. For roughness measurement of the solidified castings, measurement was conducted in 25mm run whilst 11kgf was applied for Vickers hardness indentation test. The results show that using of finer sand size besides applying pressure during solidification of LM6 alloy has significant influence on roughness and hardness of the alloy. Increasing the applied pressure and used of fine sand size expedited heat transfer from the melt to the mould and surrounding thus decreasing solidification time. Consequently, reduced casting surface roughness as well as increased in hardness.

Abstract:

Pressure of the kinetic zone is an essential factor for making defect-free castings in lost-foam casting process. The extremely high pressure causes many problems, such as reducing the melt velocity and inclusion of residual decomposition of the pattern in the castings, and very low pressure causes sand collapse. Therefore, the minimum gas pressure for preventing sand collapse is required. When the minimum gas pressure can be predicted, computer simulation becomes possible. Successful computer simulations can help reduce the number of trials and the lead time while designing new casting products. A preliminary sand experiment was conducted to predict the gas pressure and reduce the number of actual casting experiments. In this preliminary sand experiment, compressed air was used instead of gas in the kinetic zone. A new mathematical equation was proposed from the results of the preliminary sand experiment. The void ratio of the sand effect on the minimum gas pressure was included in the equation. An actual casting experiment was conducted by melting nodular cast iron to verify this equation. In the actual casting experiment, pressure of the kinetic zone in front of the metal tip was directly measured. The results obtained from the preliminary sand experiment and the actual casting experiment validated the equation.

Abstract In this study, in order to establish the manufacturing technology of the lost foam casting process, the “seal ring” and “sleeve barrel” ductile iron castings were chosen as the carriers, and the effects of some selected processing parameters, such as pattern density, pattern coating, and gating system design, on the quality of the castings produced were studied. Based upon the results obtained, the following conclusions can be drawn: (1) The density of the foam pattern employed should remain in a suitable range, no higher than 0.02 g/cm3. (2) Vibration should be applied during the sand-filling process, and continue for a certain period of time after complete fill, in order to achieve better compaction and also reduce the propensity of mold collapse during casting. (3) For the “sleeve barrel” casting, designing an suitable over-flow (or a riser) at the upper, far side of the flange of the casting can serve as a reservoir for the thermal decomposed products of the foam pattern, which can effectively eliminate both the surface defects and internal shrinkage porosities, and hence, quality castings can be attained. (4) The percent solid contraction measured in the lost foam ductile iron castings is around 1%.

This research uses two methods to prepare expandable polymer particles of PMMA or PMMA-co-PS that were used for lost foam casting. The first method is a two-step method, in which the monomer is suspended in water to polymerize into particles of appropriate size before sieving the polymer particles and putting them into a laundry fastness testing machine for foaming agent impregnation. The particles containing the blowing agent are expanded in boiling water for the test of expansion. The second method is a one-step method, in which suspension polymerization and foaming agent impregnation are simultaneously undergoing in a magnet stirred reactor. Digital camera takes the picture s of expanded particles and with Image J their particle sizes were analyzed. For two-step method, the change of either PVA concentration or agitation rate could not make obvious changes in particle size or particle size distribution. Polymerization of PMMA or PMMA-co-PS at high temperature shows coalescence leading to the production of large particles. Polymerization of PMMA-co-PS by one-step method produces only trace amount of tiny particles. The research shows increasing amounts of foaming agent could increase the percentage of expandable beads, but increase in the operating temperature in foaming agent impregnation did not make apparent influences to expanded bead size. One-step method uses only one quarter of foaming agent used in two-step method and its process time cost in the preparation of PMMA-co-PS expandable beads was also much less when comparing to two-step method.

This work is a continuation of the previous research on the production of expandable polymethyl methacrylate (PMMA) for vacuum lost foam mold application. The purpose of this research is to improve previous results by replacing the stirring peddle with turbine blades to reduce the PMMA particles size distribution with 80 % of the particles size between 0.2-0.5mm. Two different methods for the preparation of expandable particles are one-step method and two-step method. For the late, the particle size for impregnation of foaming agent is between 0.25mm-0.35mm. Impregnation was competed in reactor with a magnetically driven stirrer at high temperature and pressures. Results showed that the particles with higher MMA content had less affinity to the foaming agent,n-pentane. Therefore, additives were added to improve the affinity. Two different additives were tried: stearic acid and polyethylene wax. Addition of the additives changed the particle size distribution, and wider size distribution was obtained when adding polyethylene wax. Additives did increase the content of foaming agent in the particles though the expansion ratio did not have significant changes. In the aspect of foaming media, water did not make PMMA expanded, while glycerol could. Due to the hindrance of cooling coil in the reactor, the products by one-step method was unable to check their particle size distribution, though the products could expand successfully with water, and a larger expansion ratio was shown when additives were implemented.

This study measured the pressures developed during filling experiment using molten gray iron in the lost foam casting (LFC) process. The measured pressures included back pressure, and permeable pressure. The back pressure responded from in-mold of metal-foam interface. The permeable pressure was measured on the mould side of the coating, when gases introduced from the decomposing EPS were permeating through coating. The permeable pressure reflected the permeability of the coating while filling molten iron. This study also performs many pouring trials using a special design pattern with different coatings to evaluate the factors influencing the hot strength of coating. Strengths of coating at room temperature are also measured for comparison. Variables, which included particle sizes, types of binders, weight per cent of binder in coatings, influenced the permeability and strength of coating at room temperature and at casting temperature. Experimental results show that the coating made from flaky alumina developed a greater total length of pore channels than those made from angular silica. Increasing the particle size of the refractory increased the permeability of the coating at room temperature. The highest permeable pressure was measured. When the particle size was 74 m and acrylic resin was used as a binder. The optimum binder content was less than 1% for flaky alumina and acrylic resin binder. The optimum coating thickness was less than 0.5 mm to develop a maximum permeable pressure associated with a minimum back pressure in the mould. For a given particle size or for a given wt% of a binder, the coating added with flaky alumina and acrylic resin (binder B) develops the greatest strength at room temperature and its hot strength. If a polyvinyl acetate resin (binder A) is used, coating generally develops an inferior strength to that of acrylic resin (binder B). For a given resin added in coating, angular silica used as the refractory particle decreases the strength of coating at room temperature and its hot strength.

Abstract:

This study investigates the possibility of fabricating periodic cellular materials (PCMs) via the lost foam casting (LFC) process using aluminum alloy A356 and magnesium alloy AZ91. This approach combines the structural efficiency of PCM architectures with the processing advantages of near-net-shape LFC. An initial feasibility study fabricated corrugated A356 panels. This was followed by a study of casting variables such as pattern design, vacuum assistance, and alloying additions in order to improve the fillability of the small cross-section struts. Finally, integrated pyramidal sandwich panels having different relative densities were subjected to artificial aging treatments and subsequently tested in uniaxial compression. The A356 PCMs experienced a continuous increase after yielding while the AZ91 PCMs exhibited strut fracture after peak strength. The results showed the compressive yield strengths of this study are comparable with those previously reported PCMs produced by different fabrication methods.

Abstract:

AbstractIn the manufacturing process, the production of standardized prefabricated components is highly efficient, which can benefit the demand for mass production of standardized architecture after World War II. However, over-standardized architecture sometimes cannot satisfy the demand for uniqueness in an architecture project. At this time, bespoke components began to be used to solve the over-simplification of aesthetics of architecture. Besides, with the help of digital fabrication, bespoke components could achieve mass customization in architecture. The research designs two joints: prefabricated aluminum joints and bespoke aluminum joints, which aims to develop bespoke joints to aluminum components with ornamental characteristics and become a part of architecture with practical function and ornamental function. Furthermore, in the process of generating bespoke joints, improve the deficiency when conducting lost-foam casting.

Abstract:

The importance of smooth mold filling in the lost foam casting process has been recognized for a long time. The more uniform the filling process, the better the quality of the casting products that are produced. Successful computer simulations can help reduce the number of trials and cut down the lead time in the design of new casting products by better understanding the complex mechanisms and interplay of different process parameters in the mold filling process. In this study, a computational fluid dynamics (CFD) model has been developed to simulate the fluid flow of molten aluminum and the heat transfer involved at the interfacial gap between the metal and the expanded polystyrene (EPS) foam pattern. The commercial code FLOW-3D was used because it can track the front of the molten metal by a Volume of Fluid (VOF) method and allow complicated parts to be modeled by the Fractional Area/Volume Ratios (FAVOR) method. The code was modified to include the effects of varying interfacial heat transfer coefficient based on gaseous gap pressure which is related to foam degradation and coating permeability. The modification was validated against experimental studies and the comparison showed better agreement than the basic model. Process parameters such as initial metal temperature, foam pattern property, and gating system were investigated. The defect prediction model was also used to study the dependence of defect formation on the process variables.

Abstract:

A transient, three-dimensional, multi-phase particle-in-cell approach is used to solve for the flow of polystyrene beads in complex three dimensional geometries which represent patterns used for lost-foam casting. The numerical method solves the gas conservation equations on an Eulerian grid and the motion of polystyrene beads is calculated in a Lagrangian frame of reference. The true particle size distribution is modeled, and the particle flow ranges from dilute to close-pack. Predicted fill behavior is compared to experimentally blown patterns using colored beads and to the measured transient filling of a pattern. The colored beads show a complex fill pattern which is calculated well by the numerical method. The transient calculation compares very well with measured video data, and the particle motion has unique particle behavior unlike a fluid. Because of uncertainties in boundary conditions in production lost-foam tooling, the sensitivity of lost-foam pattern filling to boundary conditions is examined.
