Abstract:

For plate steel castings, the foundry technology was designed according to the dynamic directional solidification of proportional solidification theory. Adopting chilling process for the thick and large plane, it may cause the casting basically even cooling. Using self-feeding shrinkage in solidification achieved the dynamic directional feeding of molten steel, and the casting was poured and congealing at the same time. The shrinkage of finally congealing part was fed by small riser. Adopting this foundry technology, the large plane downwards avoided appearing the defects such as sand buckle, slag, pinhole porosity, and pore, etc.; the process yield was greatly increased with this foundry technology, too.

Abstract:

Abstract In the foundry industry, as in many other fields we seek to achieve the best quality with the least losses and the lowest cost. To meet these demands numerous plants increased automatization of their manufacturing processes. However, with changes in the production process it is necessary to change also the materials used. Not only casting alloys that are used in production, but also applied moulding and core sands are important. Proper selection and evaluation of the properties of used moulding mixtures is crucial in order to achieve a highly efficient production. In this article a new issue concerning the use of flexibility in foundry molding and core was mentioned. It explains the principles of measurement and interpretation of the obtained results for the cold-box moulding sands.

Abstract:

The short analysis of the assessment opportunities is presented for the resource efficiency in various industries and particularly in the foundry production. The developed algorithm of carrying out such assessment is presented. It is shown that such algorithm consists of five steps. They are the formation of the evaluating team, the choice of the technology or a product, the analysis of the chain creation of the added value for a technology or a product, the assessment of the current state of the technology or a product, developing the recommendations for the improvement of the efficiency of resources use. This article describes in detail the works, which need to be carried out at each stage of evaluating the resource efficiency. The evaluating map and the criteria are developed for comparing different types of the foundry technologies as well as the map for assessing the current state of the foundry technology. The result of the accomplished assessment with the described algorithm is the developed recommendations on the use of the enterprise resources.

Full text

Abstract:

Superalloys developed after the Second World War to meet the demands of the jet engine reached the limit of known alloying in the late 1960s. The continuing requirement for materials with higher temperature capabilities was met by developments in solidification and processing technologies leading to directional solidification and single crystals. By the mid 1980s it was apparent that further improvements in material temperature capability could be achieved by alloying with such exotic elements as rhenium and yttrium. The success of these alloys is due to the retarding of diffusion rates and greatly increased oxidation resistance at high temperatures. Superalloys containing these elements are generally known as second generation materials and are by virtue of their unique advantages very difficult to process. In particular the slow diffusion rates give significant difficulties with heat treatment and the retention of yttrium presents a foundry challenge of the highest order. This paper will review the advantages of second generation material and address the process problems associated with their successful introduction into service.

Abstract:

AbstractThe aim of the study was to determine the applicability of a new product added to water glass-containing foundry sands hardened with ethylene glycol diacetate. The new additive designated by the symbol “B” is a composition of aqueous solutions of modified polyalcohols, improving the sand knocking out properties. The scope of studies included testing various mechanical and technological properties of foundry sand mixtures, such as permeability, friability, life cycle of cores and knocking out properties. In the technological studies, two types of water glass with different values of the silica modulus and density, designated as R145 and R150, were used. Moulding sands were prepared with the additive “B”. For comparison, reference sands with water glass but without the additive “B” were also made. In Part I of the article, the results of studies of the effect of additive “B” on the properties of foundry sands with water glass hardened by CO2blowing were discussed.

Abstract:

Abstract The article presents chosen aspects of foundry engineering of the settlement dwellers, including the archaeometric characteristics and metal science analysis of the artefacts, as well as an attempted reconstruction of the production organization. Discovered in Szczepidło (Greater Poland), the foundry workshop is unique in Central European Bronze Age. This workshop foundry operated roughly XIV-XII Century BC. Its production is evidenced by the presence of markers of the whole production cycle: semi-finished and finished products, production waste, fragments of crucibles and casting ladles with traces of usage, and tools. On this basis, the alloys and foundry technologies used have been described. The analysis of foundry technology of copper alloys in the settlement area was carried out by observing the surface and structure of the products, semi-finished artefacts and fragments of crucibles by applying optical microscopy (OM), confocal microscopy (CLSM) and Xray radiography (RT). The investigations of compositions were made by means of the energy dispersive X-ray fluorescence spectroscopy (ED-XRF) and scanning electron microscopy (SEM) coupled with an energy dispersive X-ray analysis system (EDS).

Full text

Abstract:

This paper describes a fabrication process for realizing Indium-Phosphide-based photonic-integrated circuits (PICs) with a high level of integration to target a wide variety of optical applications. To show the diversity in PICs achievable with our open-access foundry process, we illustrate two examples: a fully-integrated 20 Gb/s dual-polarization electro-absorption-modulated laser, and a balanced detector composed of avalanche photodiodes for detection of 28 Gb/s optical signals. On another note, datacenters are increasingly relying on hybrid integration of PICs from different technology platforms to increase transmission capacity, while simultaneously lowering cost, size, and power consumption. Several technology platforms require surface coupling rather than the traditional edge coupling to couple the light from one PIC to another. To accommodate the surface-coupling approach in our integration platform, we have developed a strategy to transfer the following optical Input/Output devices into our fabrication process: grating couplers, and vertical mirrors. In addition, we introduced etched facets into the process to improve the usability of our edge-coupling elements. We believe that the additional flexibility in Input/Output interfacing combined with the integration of multiple devices onto one PIC to reduce the number of PIC-to-PIC alignments can contribute significantly to the development of compact, low-cost, and high-performance datacenter modules.

Abstract:

The research of new ceramic coatings has an important role in the improvement and development of new casting methods, especially casting with meltable and evaporable patterns. The selection of ceramic materials to be used as refractory fillers, materials for the binding system and additives for maintaining suspension stability, will be carried out in accordance with the casting method selected for the actual alloys and types of castings. The actual importance of these problems is reflected in the fact that the application of quality coatings increases the production efficiency by producing high quality castings, increases the metal yield and eliminates the expensive casting operations-cleaning and machining. Cordierite ceramic are of great importance in modern technology. Standard raw materials, kaolin, talc, MgO, alumina, feldspar were used in the synthesis of cordierite ceramics. Sintered cordierite of the composition 2MgO ? 2Al2O3 ? 5SiO2 was used as a refractory filler in a ceramic coating for evaporative polystyrene patterns in a new casting technology, the EPC Method. Cordierite characterization was carried out by means of X-ray diffraction. The characteristic temperatures for carrying out solid state reactions in the three component system 2MgO ? 2A12O3 ? 5SiO2 were determined by differential thermal analysis in the range from ambient temperature to 1100 ?C. In order to realistically evaluate possible cordierite application in the production of evaporative pattern ceramic coatings, concurrent analyses with a talc-based coating were carried out. Cordierite ceramics have not yet been used in casting.

Abstract:

For the steel castings which is thin wall, uniform thickness, complex structure, and no special mechanical properties, it is feasible that the foundry technology was designed according to the last solidifying feeding mechanism. Adopting this process for the thin wall steel castings, the pouring temperature must be controlled and the gating system be designed rationally. Using self-feeding shrinkage in solidification, and the casting was poured and congealing at the same time. The shrinkage of finally congealing part was fed by small riser or gating system (no riser). Using this foundry technology, the casting process yield and surface quality of casting may be improved, the production cost is reduced, and the requirements of mechanical properties can be met.

Abstract:

To understand the thermal distribution in a complex structure and high quality linkage casting, a mathematical model of temperature and stress field was established. Numerical simulation techniques was applied by using Procast software in the temperature and stress fields of solidification process, and the foundry defect such as old lap, misrun, shrinkage and dispersed shrinkage was predicted. The stress distribution and deformation in cooling process of casting were analyzed. The simulation results can supply a scientific foundation for foundry technology.

Abstract:

Abstract In 1965, Gordon E. Moore, the co-founder of Intel stated that numbers of transistors on a chip will double every 18 months and his theory called the Moore's Law. The law had been the guiding principle of chip design over 50 years. The technology dimension is scaling very aggressively in IC foundry. For example, TSMC announced their 5nm Fin Field-Effect Transistor (FinFET) process technology is optimized for both mobile and high performance computing applications. It is scheduled to start risk production in the second half of 2019.[1] To overview the semiconductor supply chain included IC foundry, wafer bumping, IC carrier, PCB (Printed circuit board) and OSAT (oversea assembly and testing)… etc., the IC carrier and PCB technology dimension scaling are far behind than the IC foundry since many reasons for the traditional industry. The industry needs different kinds of breakthrough approaches for the scaling of via and strip line in next generation interconnection. Traditional organic substrates faces many challenges of warpage, surface roughness and material dimension stability issues for manufacturing and high density I/Os with very fine line interconnections. To breakthrough these challenges, the materials of glass carrier, new photo-imagable dielectric (PID) and advanced equipment were evaluated for the fine line and fine via interconnection. In the papers, there are many PID and non-PID materials were surveyed and compared for fine via (< 10μm) interconnection or low loss of high frequency application. The first candidate was chosen for redistribution layers (RDL) fabrication by using 370mm × 470mm glass panels. Semi additive process (SAP) was used for direct metallization on glass panel with different build-up dielectric materials to form daisy chain test vehicles. The process, fabrication integration and electrical measurement results of daisy chain showed good continuity and electric resistance in the glass panel substrate. The reliability of the thermal cycling test (TCT) and highly accelerated stress test (HAST) were evaluated as well in this study.

Abstract:

Recent research in the process of die casting production of aluminium alloys which are nowadays deeply implemented in the rapidly developing automobile, shipping and airline industry aims to increase the manufacture and quality properties of the casting in order to obtain its high mechanical properties at acceptable economic costs. In terms of ensuring the quality indicators in the production of aluminium castings it is necessary to pay close attention to internal structural quality of the castings characterized by type and extent of foundry defects (cavities, Al2O3 particles, internal cold laps). The presenting contribution deals with the analysis of the fracture process, the microorganism disturbance of test samples, the impact of casting speed on the occurrence and extent of the castings porosity and reasons for the internal foundry defects of casting alloys EN 43100 manufactured by die casting technology.

Abstract:

High technology products have certain salient characteristics that differentiate them from low technology consumer products. The marketers of the products of the latter type may adjust their marketing strategies to reflect relatively unchanging technological conditions. High technology companies, however, must recognize that both technological and market conditions are rapidly changing. This dynamic environment necessitates a greater consideration of both marketingand technology-related aspects. One of the major objectives of this paper is to explore the context in which the terms ‘high technology’ products/markets/industries have been used in the extant literature. Because of the focus of earlier studies on some specific elements and stand-alone issues in this area, this paper fills the gap for a broad overview of the marketing-specific issues in high technology area and relates it to the lessons drawn from practice. The theoretical results illustrate the following: Several definitional viewpoints and characterizations of high technology industries exist in the literature, namely (i) uncertainty, (ii) input-based, (iii) output-based, (iv) increasing returns and network externalities, and (v) techno-paradigm. One of the more popular views, uncertainty, characterizes the uncertainty in high technology industries in terms of (i) market, (ii) technology, and (iii) competition. Another popular techno-paradigm view refers to the set of all industries which conform to a certain set of paradigmatic trends such as enormous R&D expenditure, predatory competition, and substantial diversification and innovation waves. The high technology markets must focus on both demand-side and supply-side marketing. Several examples from the literature contradict the popular notion that the superior product will win out in the marketplace. A critical aspect particularly relevant to the high technology products diffusion is that there might be ‘cracks’ or ‘gaps’ in bell-shaped adoption curve (e.g., innovator-early adopter and early majority-late majority) also known as ‘chasm’ or the ‘valley of death’ for high technology products. Newer and different marketing research techniques, such as census approach, lead user study, and outcome-based techniques are more relevant for high technology products. The case study discussed in the paper suitably supports the theoretical results illustrating the following situations: A majority of the small-scale grey iron foundry units in India employ cupola furnace for melting using coke as fuel with inefficient combustion and higher energy consumption. The Energy and Resources Institute (TERI) set up a demonstration plant consisting of an energy-efficient cupola design called the divided blast cupola (DBC) at a foundry unit in Howrah. After successful demonstration, the challenge was to replicate the technology among other foundry units. The major barriers to adoption were: (i) prevailing practice, (ii) limited in-house technological capability, and (iii) investment. Future work by TERI envisages the need for adopting a philosophy of vendor development and conducting formal marketing research study.

Abstract:

The thin wall stainless steel castings is difference to ordinary steel castings in foundry technology. This paper discussed the problems of thin wall stainless steel castings which appearing in the flow controlling board for warm-air pipe, and put forward the foundry technology of this stainless steel castings based on the principle of directional solidification and fast pouring mechanism. According to the theory, twin gating system has been designed for the controlling board castings, and two ladles are pouring into the open twin gating system at the same time. The shrinkage of finally congealing part was fed by two risers. The practice has shown that the design is feasible, there is not cold shut, misrun, scab, and oxidizing for the castings, and the requirements of mechanical properties can be met.
