ADDITIVES MANUFACTURING A TECHNOLOGICAL

FUTURE IN MATERIALS PROCESSING BY CASTING

 

Material processing by casting requires the use of various types of raw materials, numerous auxiliary materials, various forms of energy and technological fluids flowing through varied route in several specific types of plant and machinery. The changes that have occurred in industrial technologies for the past 20 years under the new paradigm „changing technologies under the influence of the economic, social and political” and left their mark on the field for obtaining substantial and parts by processing materials by casting. Recent decades have marked the appearance in the current industrial operation in the processing of materials, concerns more highly bound to reduce and optimize energy consumption and materials linked with improving the environment. This development has led to the widening, deepening and broadening the scope in order of the best processing methods to ensure the sustainable development as on real. As such materials processing moulding consider key issues related to the technological side and those on the economic side, but also those that are imposed by increasing quality and minimizing environmental impact. Exploring the use of additive manufacturing system based on fundamental data, analyses, measurement and experimental results the scope of this article. This analysis leads to the idea of perspective as moulding materials processing has the potential to become a driving force to achieve a sustainable society by introducing efficient production practices that contribute to a considerable decrease negative environmental impact.

ECOTECHNOLOGICAL APPROACH IN REUSE OF THE
PLASTICS IN THE INDUSTRIAL FURNACES
Today waste plastics generated from a variety of sources that lead to
the significant increase in quantities of waste and the urgent need to reduce the
amount of waste. Advanced recycling of plastics contributes significantly to
enhance environmental management implementation environment and
economy that allows coexisting harmoniously in the paradigm of sustainable
development the beginning of this century. Recycling of plastics in industrial
furnaces can be a solution for the reduction of Environmental Impact and
efficient use of limited natural resources and the process of exhaustion.
Development objectives in the field are related to the implementation of a
system to ensure a harmonization of requirements processors to achieve full
recovery of waste and environmental technologies. Implementation of a new
technology for recycling of plastics can be. Significant differences problematic
due to properties related to the weight of the different components of the ecoefficiency

Advanced recycling of plastics contributes significantly to enhance environmental management implementation that allows environment and economy to coexist harmoniously in a sustainable development paradigm of the beginning of this century. Today plastics are generated from a variety of sources and large amounts of material are deposited, resulting in difficulties in storage. Industrial processing or storage of plastics is extremely difficult and has become a social problem in recent years. Recycling of plastics in industrial furnaces can be a solution for the reduction of environmental impact and efficient use of natural resources limited and the process of exhaustion.

DEVELOPING OF THE HIGH-STRENGTH
LOW-ALLOY STEEL (HSLA)
In present high-strength low-alloy steels have gained a significant
position in the engineering arena and began the most important ferrous alloy
design and manufacture of metal structures. Achieving high-strength low-alloy
steels usually require a greater complexity to the design and steel processing to
ensure structural integrity. These include a complex system in which the
processing conditions are crucial and require an appropriate design of steel
grades used. With increasing resistance of the material and economic use of a
welding process can be achieved remarkable cost savings in construction
works. Now high-strength low-alloy steels are used for almost all complex
metallic structures: tanks, bridges, construction equipment, machinery etc. This
is largely confirmed by the use of high strength steel with vanadium micro Highstrength
