This study aimed to develop an extrusion and pultrusion system for producing carbon fiber-filled thermoplastic pellets. The extruder delivers a plastic melt impregnation die in sufficient volume is pulled out along with the fibers. fibers pass sideways stretched condition through spreader pins attached pool, which can then be wetted optimally. wetting effect was also improved by immersing fiber...

slab method of analysis has been used for solving metal forming problems for a long time. however it has been restricted to plane strain and axisymmetric problems due to limitations in its formulations. in this paper a new formulation has been proposed so that it could be applied to three dimensional problems in metal forming. a parametric slab has been considered in this analysis and the force...

Signal processing techniques have been developed for extracting quantitative indicators of the performance of extruders processing soft-solid pastes from the data recorded by pressure transducers located near the extrusion die. Such techniques have been applied previously to isothermal ram and screw devices using retrospective methods. This article reports on the scope for application of retros...

In this work, different friction models available in HyperXtrude had been investigated the context of hot forward extrusion simulation aluminum alloys. Extrusion trials were carried out for EN AW 6060 and 6082 at temperatures ram speeds. The forces as well material near exit die recorded used validation simulations. FE-simulations each trial HyperXtrude. Initially, calibrated only two trials. T...

Extrusion is one of the widest used and the most basic processes of plastic forming, and the metal flow in extrusion is affected by many factors, such as friction, die shape, billet temperature and so on. Among these factors, friction is the key boundary condition to determine the property of the extruded products. In this paper research and measurements of velocity fields and impact of frictio...

Abstract. In copper extrusion, the dies are continuously subjected to high thermo-mechanical stress. This results in elastic and plastic die deformation as well extensive wear. To estimate strain of possible hard phase surface modifications during service, knowledge behavior extrusion is required. Therefore, made four different tool materials was investigated present study. The applied were hot...
