Abstract:
AbstractA new process, called thermoset in-mold forming, for combining thermoset master forming and thermoset forming in one mold is in development. A pre-impregnated continuous-fiber reinforced sheet based on epoxy (prepreg) is formed in the injection molding machine, followed by instantaneous overmolding of a short-fiber reinforced epoxy compound in one step. Compared with conventional processes in which thermoset injection molding, prepreg compression molding, and hence curing of the materials are separated, the new process allows for the combination in one step and simultaneous curing of both components. The result is a hybrid component, which features a continuous-fiber reinforced part for higher mechanical performance and a short-fiber reinforced part with high design freedom for integration of additional functions. For a successful combination of both materials in one process, it is essential to investigate the bond strength between them in relation to the processing parameters and their influence on the degree of cure. This paper analyzes the influence of the mold temperature in this process on curing degree, bond strength, and the processing viscosity.

Abstract:
Alpha-case formations between investment molds and TiAl alloys were investigated for economic TiAl alloys net-shape forming. The α-case reactions between mold and TiAl alloys were characterized by using optical microscopy and a hardness tester. In the case of TiAl alloys, there were no α-case formation reactions. The α-case was formed not only by interstitial oxygen elements but also by substitutional metallic elements dissolved from mold materials. There were neither interstitial nor substitutional α-case formations since TiAl alloys have both negligible solubility of oxygen and low activity in molten states. The results of the investment casting of TiAl alloys confirmed that the casting route in our study can be an effective approach for the economic net-shape forming of TiAl alloys automotive parts.

Abstract:
Purpose In this paper, the effects of the adhesive and curing agent contents on the tensile strength, bending strength, gas evolution and gas permeability of three-dimensional printed sand molds are studied. A strength model of the three-dimensional printed sand molds is proposed. The multi-material composite sand mold forming test is carried out. In addition, the mesostructure of the sand mold is studied. Design/methodology/approach The performances of three-dimensional printed sand mold such as tensile strength, bending strength, gas evolution and gas permeability are studied using the standard test methods. The mesostructure of the sand mold is studied by digital core technology. Findings A sand mold strength model based on the resin adhesive content, curing agent content and sand mold compactness are obtained. Two types of multi-material composite three-dimensional printed sand molds are proposed. An increase in the curing agent content in the sand mold widens the mesoscopic characteristic size distribution of the sand mold, and large-sized mesostructures appear, resulting in a decrease in the sand mold bearing capacity. Practical implications Process parameters that affect the performance of three-dimensional printed sand mold are revealed. The sand mold bearing curve provides a reference for the ultimate design of three-dimensional printed sand mold. Originality/value The paper deals with experimental work on the performance and mesostructure of multi-material composite three-dimensional printed sand mold with different contents of adhesive and curing agent. That gives a perspective on future designs of sand mold based on these principles.

Abstract:
This paper presents a glass molding press (GMP) method to fabricate microgroove array and micropyramid array on the glass plate by replicating the shape of the mold to the glass surface. The differences between microgroove forming and micropyramid forming were investigated by experiments and finite element method (FEM) simulations. Microgroove arrays and micropyramid arrays were generated on the flat glass plate in the GMP process by using an electroless-plated Nickel Phosphorus (Ni-P) mold, on which the microstructures are fabricated by micro cutting. Furthermore, FEM simulations were used to trace the stress distribution and the strain distribution during the glass deformation, which illustrates the glass material flow in the microgrooves and the micropyramids on the mold during pressing. By comparing the processes between microgroove forming and micropyramid forming, the differences between them observed in the experiments were explained by the simulation results. Finally, some techniques to improve the forming accuracy were proposed.

Abstract:
Ceramic corundum molds on hydrolysed ethyl silicate solution which have insufficient inertness to poured alloys are widely used in the production of castings from reactive metals alloys. This is due to the presence of free silica, which is a strong oxidant of such alloy components as aluminium and titanium in vacuum conditions, in the form of a high content. To solve the indicated problem using aluminium-borophosphate concentrate, chemically cured with periclase, as a silica free binder of ceramic corundum molds was suggested. The use of the combination of the indicated mold materials allows not only enabling chemical inertness of the molds, but also operating the process of mold forming. The developed technology provides the acceleration of the mold manufacturing cycle in 4...6 times, the increase the strength of the mold covers, the reduction in the heat-resistant alloy casting cost. It enables significant improvement of the quality and increase of the economic efficiency of manufacturing of precision casting from reactive metals and alloys.

Abstract:
It is known that a newly formed glass container will only possess a very small fraction of its theoretical strength. This suggests that damage occurs on the surface of the glass melt during the forming process due to glass to mould contact and hot glass handling. It might be expected that any damage inflicted on the surface of a glass article during manufacture would heal at the elevated manufacturing temperatures used, however this does not appear to be true. Therefore, the actual mechanism by which glass strength is reduced during forming needs to be fully understood and the work presented in this thesis addresses this problem. Experiments, therefore, have been carried out here which simulate the formation of glass articles using an experimental pressing rig by systematically altering processing parameters such as the mould material, surface fmish of the mould, pressing temperature and atmosphere. Processing parameters that are used industrially for the formation of glass containers were generally reproduced wherever possible in order to investigate the glass-to-mould interaction. The interaction of both a cast iron mould material and carbon-carbon composite materials with a soda-lime-silica glass were examined using the techniques of scanning electron microscopy, x-ray photoelectron spectroscopy and atomic force microscopy in order to determine the type and extent of surface damage formed. The surfaces of the pressed glass samples made were found to contain defects of embedded particles and indented dimples. The embedded particles found were usually due to bulk material transfer from the plunger material used. The texture found on the surface of the pressed glass samples was found to be directly affected by the surface fmish of the plunger. Pressing glass samples using a cast iron plunger at an initial plunger temperature below 450°C resulted in a randomly rippled 'chilled' surface. As the initial temperature of the plunger was increased, the surface texture of the pressed glass became a closer replica of the plunger surface. The use of vacuum assistance to form the glass samples also resulted in the surface of the pressed glass becoming a closer replica of the original plunger surface, even at lower pressing temperatures. The surfaces of the cast iron and carbon-carbon composite plungers appeared to have been affected by the initial plunger temperatures used. As the initial pressing temperature was increased, the amount of oxidation for both material types increased. In the case of the carbon-carbon composite materials investigated, both the matrix and fibres were found to have broken down at the pressing temperatures used. X-ray photoelectron spectroscopy, of the pressed glass surfaces and the plunger materials indicated that sodium ions had migrated from the glass melt to the plunger surface during forming.

São produzidas e testadas em operações de tixoforjamento pastas obtidas por três distintos processos: fusão parcial controlada de estrutlJ'aS dendríticas grosseiras, fusão parcial controlada de estruturas ultra-refinadas e pastas obtidas por agitação mecânica do líquido durante solidificação. É produzido ainda um compósito A356 + Ab03 obtido por compofundição. Os tixoforjados foram submetidos à análise metalográfica para caracterização microestrutural, medindo-se a fração da fase primária e o tamanho médio de glóbulo ou roseta da fase sólida. Os resultados obtidos mostram a viabilidade da utilização de moldes não metálicos e operações de tixoconformação com produtos de bom acabamento superficial e dimensional.

Neste trabalho foi desenvolvido o material e o processo de fabricação, que possibilitasse a fabricação de grampo de feixes de mola para veículos comerciais leves, médios e pesados, sem a necessidade de aplicação de tratamentos térmicos como têmpera e revenido. Assim, foram desenvolvidos/analisados cinco tipos de aço com adição de cromo, níquel e silício que possibilitassem a conformação a frio do grampo, garantindo as propriedades mecânicas requeridas pelos grampos, tais como: resistência à tração (900 MPa mín.), limite de escoamento (720 MPa mín.), alongamento(10% min.) e dureza(24-32 HRC). Os aços desenvolvidos exibiram uma microestrutura composta de grãos de perlita e ferrita, sendo que o tamanho de grão perlítico (ASTM) entre 9 a 11 foi obtido pela adição dos elementos de liga alumínio e vanádio que atuaram como refinadores de grão. A avaliação das propriedades mecânicas foram realizadas segundo a norma ASTM A-370 e os corpos de prova foram ensaiados em um sistema dinâmico MTS 810. As análises microestruturais dos aços, após a deformação a frio, foram realizadas por meio de microscopia ótica e eletrônica de varredura, com o objetivo de se identificar a deformação a frio nas áreas desejadas. A validação final do aço e do processo de fabricação do produto foi obtida após a conclusão do ensaio de fadiga que foi realizado em temperatura ambiente, sob carregamento cíclico tração-tração com R = 0,1 e freqüência de 30 Hz, onde a metodologia Probabilidade acumulada da falha (Weibull) foi utilizada para auxiliar na conclusão final do projeto. Foi observado que o aço tipo-4 com adição de cromo (0,21%) apresentou o melhor resultado em fadiga.

Abstract:
Aspergillus are ubiquitous molds that grow quickly, forming fluffy colonies in culture. Under microscopic examination an erect conidiophore has a swollen vesicle covered with phialides, which give rise to conidia. In tissue, hyphae predominate. The most common pathogen is Aspergillus fumigatus. Other pathogenic species include Aspergillus flavus, Aspergillus terreus, Aspergillus niger, Aspergillus ustus, and Aspergillus nidulans. There are increasing reports of other rare species causing infection.

Abstract:
Recent advances in numerical simulation capabilities have made the modeling of glass container forming processes feasible. These forming models must include large free surface deformations, viscoelastic behavior, conjugate heat transfer, and complex contact phenomena between the glass and the forming molds. One of the most critical inputs to these models is the heat flux between the glass and mold. A simple one-dimensional heat transfer model was developed for use in conjunction with a complex three-dimensional forming model to determine the heat flow between the glass and forming mold. Initial comparisons to experimental results indicate the simple model captures the primary physics of heat flow during forming. This paper describes an experimental effort to determine the time varying contact conductance between molten glass and container forming molds. The experimental apparatus is capable of independently varying the glass pressure, glass temperature, mold temperature, and glass type. Initial validation of the experimentally determined contact conductance function in conjunction with the one-dimensional heat transfer model utilized within a glass forming model indicate good agreement between calculated and measured results. These forming models are now able to determine final glass container properties without having to resort to the trial-and-error process currently utilized in glass container production.

Abstract:
Abstract Mold design can be a difficult, time-consuming process. Particularly for rapid tooling applications, delivering prototype parts with turn-around times of less than two weeks requires fast, proven mold design methods. We present a region-based approach to automated mold design that is suitable for simple two-piece molds (consisting of core and cavity), as well as molds with many additional moving sections. In our region-based approach, part faces are partitioned into regions, each of which can be formed by a single mold piece. The basic elements of our approach are concave regions (generalized pockets) and convex faces since these elements are central to the identification of regions. This paper focuses on the initial steps of automated mold design, including a problem formulation and methods for identifying the basic elements from part faces. By seeking to minimize the number of mold pieces, different partitions of faces into regions are explored until the smallest number of regions is found. During this process, faces may be split and allocated to different regions. The scope of this paper is limited to the initial steps of the region forming process. We present alternative region forming algorithms and analyze their computational complexity. Our approach is illustrated with two examples of industrial injection molded parts.

Abstract:
To complement existing resin flow control strategies currently under development for Vacuum-Assisted Resin Transfer Molding (VARTM), and to provide the ability to react to unexpected changes in resin behavior during injection, a new technique for resin flow manipulation has been investigated. This approach consists of a semi-cylindrical shaped vacuum chamber placed on a mold which, when evacuated, increases the permeability of the region under the chamber by lifting the bag atop the mold. A finite element model has been developed to predict the resin flow within the mold while using the external chamber. Laboratory testing has shown significant modification in resin flow with reduced injection time. Using the external chamber, a robotic system has been prototyped that identifies dry regions forming during injection via computer vision, deploys the vacuum chamber over the mold with a robotic arm, and actuates the chamber in order to modify and correct the resin flow within the mold. Test results using lab-scale molds with large variations in preform permeabilities indicate that the robotic system can correct and/or modify the resin flow within a mold in real time, thus eliminating dry, unimpregnated regions. This computer-based method has the potential to significantly enhance molded part quality and consistency by eliminating resin starved regions within a molded composite part.
