In this research, we explore which activities may be subject to coopetition in the plastic and composites industry. We also compared main antecedents, outcomes, moderators of industry with those identified existing literature. Results indicate that respondents have a desire for coopetition, but not close customer (sales, after-sales service, information). On other hand, are favor collaborations...

In this paper we will present a mechanical study made on the design of thermal conductive plastic parts. Out our derived new rules that are useful for engineers have to create parts built from type materials. We used Catia V6 software modelling and ANSYS Moldflow simulate behaviour real components. The solutions resulted trials improving quality plastics. test simulation results lead us designi...

The article discusses the tools as a means of influencing regional authorities, used to implement policy aimed at forming an effective structure industry coal-mining region. There are five main groups tools: economic, financial, organizational, legal and informational. Building industrial is one most important tasks, solution which increases efficiency stability country's economy whole. This ta...

Asymmetric Incremental Sheet Forming (AISF) is a relatively new manufacturing process. In AISF, a CNC driven forming tool imposes a localized plastic deformation as it moves along the contour of the desired part. Thus, the final shape is obtained by a sequence of localized plastic deformations. AISF is suitable for small series production of sheet metal parts as needed in aeronautical and medic...

The paper is focused on issues of processing of non-ferrous metals in practice, namely on Mg-Al-Zn based on magnesium alloys with graded Al contents. It is well known that forming of these alloys is difficult since this feature is caused by their crystallographic arrangement. Nevertheless, application of appropriate methods of forming, such as e.g. some of SPD processes, makes it possible to ac...

The ability of a metal to be subjected forming processes depends mainly on its plastic behavior and, thus, the mechanical properties belonging this region stress–strain curve. Forming techniques are among most widespread metalworking procedures in manufacturing, and aluminum alloys great interest fields as diverse aerospace sector or food industry. A precise characterization is crucial estimate...

Aluminum alloys are considered a lot in the automotive and aerospace industry because of their high strength to weight ratio. In this manuscript, the gas forming process of aluminum AA6063 tubes at high temperatures up to 500°C is investigated, through experimental and numerical tests. Therefore, an experimental setup is prepared and so, tube specimens are formed in a die with square cross sect...

In search for new manufacturing process, Single Point Incremental Forming (SPIF) emerged to be one of the useful processes for forming complicated shapes. This is a flexible forming process which eliminates the die, punch and errors due to them. It is widely used for batch production of different shapes which has applications in diverse fields like automobile, aerospace, medical industry, packa...

In order to further reduce the weight of car components while at the same time maintaining performance and safe life it is necessary to enhance the simulation process. This is especially important for chassis parts which have not only a high dynamic load but are also partly undamped. To reach this goal, the logical step is to couple the successive operations of forming, assembly and virtual per...
