Abstract:
In this paper, the effect of traction speed on the four-lumen plastic micro-catheter (FLPMC) was numerically studied. Moreover, the numerical simulations of FLPMC based on two kinds of extrusions, i.e., traditional extrusion and gas-assisted extrusion were performed and compared. Numerical results show that with the increase of traction speed, the sizes of FLPMC for both extrusions all decrease. The sizes of FLPMC based on gas-assisted extrusion are sightly larger than those of the traditional extrusion. To ascertain the reasons, the flow velocities, pressure, shear stress and first normal stress difference distributions of melt based on both extrusions under two different traction speeds were obtained and compared. Results show that with the increase of traction speed under the fixed volume inlet flow rate, the radial flow velocities of melt at the outlet of die decrease but the axial flow velocities increase, which results in the decrease of the die swell at the outlet of die and the size shrinkage of exit face for the FLPMC based on both extrusions. However, for the gas-assisted extrusion, the axial velocities are larger, and the pressure, shear stress and first normal stress difference are far less than those of traditional extrusion, which results in the larger unit volume flow rate, then the sizes of cross-section face are larger than those of the traditional extrusion.

Abstract:
Sandglass extrusion is an ultrafine grain size method. Due to the repetitive and multiple extrusions, large strain can be accumulated and ultrafine grain size can be obtained. Some factors can affect the experimental results of sandglass extrusion, such as extrusion ratio, number of extrusion, extrusion temperature, friction and free space in mould cavity etc. These factors have different effects on material microstructures, properties and defects. In this paper, the effects of extrusion ratio and friction on material microstructures during sandglass extrusion process have been discussed and theory analysis and experimental results have been reported.

Abstract:
It is widely known that the continuous extrusion forming (CONFORM) process can produce ultra-long seamless products of various cross-sections for aluminum, copper and their alloys. In this paper, the continuous extrusion of AZ31 magnesium alloy is achieved. The effect of extrusion wheel velocity on microstructure of extrusions is investigated. The results indicate that grain refinement is realized during CONFORM process. As the extrusion wheel velocity increases, the grain size at the center of a cross section perpendicular to the extrusion direction of an extrusion increases, and the grain structure tends to become uniform in the surface region.

Abstract:
Lotus-type porous aluminum with cylindrical pores oriented in one direction was deformed by Equal Channel Angular Extrusion (ECAE) through a 150° die with sequential 180° rotations, and the pore morphology and Vickers hardness after the extrusion were investigated. The Vickers hardness increases with increasing number of passes in the extrusions both parallel and perpendicular to the pore direction, accompanied by the decrease of porosity. The densification occurs more easily in the perpendicular extrusions than in the parallel extrusions, and the large deformation by the densification gives rise to the large increase in the Vickers hardness for the perpendicular extrusions.

Abstract:
In order to meet the industrial demands for large-sized bulk ultrafine-grained materials, which were prepared by severe plastic deformation, the law curves of equivalent strain, equivalent stress and load of different-sized extrusions had been gotten by the finite element simulation of ECAP. The extrusion size has little effect on the values and distribution law of equivalent strain as well as the values of equivalent stress. With the increase of extrusion size, the distribution uniformity of equivalent stress decreases, and the extrusion load increases. Although the ECAP of the large-sized extrusions improve the requirements of mold and equipment, the chunk of evenly ultrafine-grained materials can be obtained by multiple passes.

Abstract:
Equal channel angular extrusion (ECAE) is a solid-state extrusion process for modifying microstructures via severe plastic deformation without modifying the specimen cross section. In this study, changes in the microstructure and mechanical properties of polypropylene resulting from extrusion orientation route A (no rotation between extrusions) and extrusion orientation route C (a rotation of 180° between extrusions) are investigated using a 90° die-angle tooling outfitted with back pressure. Important differences are reported for the ECAE-induced deformation behavior between the two processing routes. A focus is made on the occurrence of heterogeneous plastic deformations (periodic shear banding and warping) for both routes and the control and inhibition of the plastic instabilities via regulated back pressure and ram velocity. Wide-angle X-ray scattering is carried out to characterize the structural evolution as a function of the processing conditions including route, extrusion velocity and BP application. The mechanical properties of the specimens machined from the ECAE pieces are examined under different loading paths including uniaxial tension/compression and simple shear. Full-field displacements converted to volumetric strains revealed the profound impacts of the processing route on the deformation mechanisms during tensile deformation.

Abstract:
In the present research, the influences of different extrusion ratios (15, 30, 45, 60, and 75), extrusion temperatures (300 , 340 , 380 , 420 , and 460 ), and subsequent heat treatment on the mechanical properties and microstructure of as-cast ZK60 magnesium alloy have been investigated through the tensile tests and via metallographic observation. The results show that forward extrusion process can refine the microstructure of as-cast ZK60 alloy effectively. If as-cast ZK60 alloys have been extruded with the extrusion ratio 45 at 380 ,420 and 460 , respectively, and then post-heat treatment was conducted, the ZK60 alloy’s strength is higher under T5 than T6 treatment. For as-cast ZK60 alloy processed by extrusion and T5 method, the most appropriate temperature for extrusion processing is 300 , at which its tensile strength are highest provided the extrusion ratio is 30 but yet its plasticity is best provided the extrusion ratio is 45. If forward extrusions were conducted at 380 , mechanical properties of ZK60 alloy have little difference as the extrusion ratio varies. When T6 treatment was conducted for the extruded bars, their mechanical properties were improved little, moreover, the bigger the extrusion ratio is, the higher the tensile strength and elongation of the extruded bars become.

Abstract:
AbstractExtrusive tooth movements are an important resource in orthodontic treatment and allow the manipulation of teeth and periodontal tissues. They can be performed quickly or slowly, depending on the patient’s need. Rapid extrusion is indicated for cases in need of prosthetic preparation or restoration, where the bone and gingival tissues are intact, such as horizontal and oblique fractures, coronary or external root resorption, iatrogenic perforations (trepanations) and the presence of subgingival caries. The aim of this study is to describe the treatment of a patient who had a coronary fracture of the right upper central incisor, with a limit located 1 mm above the level of the bone crest. Rapid orthodontic extrusion was performed, to restore biologic distances and allow the preparation for prosthesis. It started with partial differentiated bonding of a fixed orthodontic appliance to the upper arch, to allow for a 3mm orthodontic extrusion. At the end of the extrusion, periodontal surgery was performed to increase the clinical crown and endodontic treatment. After these procedures, the case was concluded with the fixed prosthesis installation. The realization of an integrated planning allowed the restoration of aesthetics, with preservation of the functional periodontal limits for the patient. Keywords: Tooth Movement Techniques.

ResumoOs movimentos dentários extrusivos constituem um recurso importante no tratamento ortodôntico e permitem a manipulação dos dentes e dos tecidos periodontais. Eles podem ser realizados de forma rápida ou lenta, dependendo da necessidade do paciente. A extrusão rápida está indicada para casos com necessidade de preparo protético ou restauração, onde os tecidos ósseo e gengival encontram-se íntegros, tais como fraturas horizontais e oblíquas, reabsorções coronárias ou radiculares externas, perfurações iatrogências (trepanações) e presença de cárie subgengival. O objetivo deste trabalho é descrever o tratamento de uma paciente que apresentava fratura coronária do incisivo central superior direito, com limite localizado 1mm acima do nível da crista óssea. Realizou-se extrusão ortodôntica rápida, com a finalidade de restabelecer as distâncias biológicas e permitir o preparo para prótese. Iniciou-se com colagem diferenciada parcial de aparelho ortodôntico fixo no arco superior, para permitir a extrusão ortodôntica de 3mm. Ao término da extrusão, realizou-se cirurgia periodontal para aumento da coroa clínica e tratamento endodôntico. Após esses procedimentos, o caso foi finalizado com a instalação da prótese fixa. A realização de um planejamento integrado permitiu o restabelecimento da estética, com preservação dos limites periodontais funcionais para a paciente.Palavras-chave: Técnicas de Movimentação Dentária.

Abstract:
Rheo-extrusions of A7075 aluminum alloy were carried out utilizing semi-solid slurries with different solid granule sizes, which were made by a simple method combined a thin upright tube with a water-cooled tube. Every structure of slurries was granular and average solid granule sizes could be controlled by 0.05 to 0.11mm. These slurries were extruded to round bars at extrusion ratio of 36 and press ram speed of 10mm/s mainly, just after cooling to 833K ( fs > 0.9 ). All of the slurries could easily be extruded to bars with smooth surfaces at much low extrusion forces than those of hot-extrusions. Tensile strength of rheo-extruded bars after solution treatment increased with decreasing of the solid granule size. Peak hardness level at T6 condition equivalent to that of hot-extrusion could be obtained at the finest solid granule size.

Abstract:
The aim of the investigation is to characterize the behaviour of billets composed of different aluminium alloys chips, shape and size. The billets were processed by plastic deformation in order to obtain useful parameters to make final products with good aesthetic-structural characteristics. This is made possible by direct recycle of chips with plastic deformation processes, in specific with a chip-based hot extrusion process. This technique is very interesting at an industrial level where the chips coming from various aluminium alloy machining procedures are accumulated together. The classic secondary aluminium production process by re-melting already saves 95% of energy in comparison to primary aluminium production from mineral (Bauxite). As previously shown from researches on Chip Extrusion, there is a higher energy saving through direct extrusion of chips and scraps pre-compacted in chip-based billets without re-melting. The research has the objective of testing the optimal combination of process parameters for different mixes of alloys in order to obtain the desired profiles; at the same time a FEM (Finite Element Method) simulation is implemented with HyperExtrude and MatLab software. The code is expected to describe processes with different parameters and give results similar to the experimental ones.

Abstract:
L'industrie de la terre cuite valorise les materiaux de la terre en extrudant des pates d'argiles. Le but de cette etude est la maitrise de la mise en forme a vitesse elevee de ces pates et des defauts d'extrusion. La caracterisation des proprietes physiques et rheologiques des pates, notamment dans des conditions non consolidees et non drainees, les fait apparaitre comme des materiaux plastiques heterogenes. Les proprietes d'interface des pates sont caracterisees grace a un tribometre concu pour l'etude des frottements a vitesse elevee. Nous proposons une loi de frottement suggerant un couplage des effets de la vitesse de glissement et de la pression normale. Une etude experimentale systematique a permis d'obtenir les proprietes d'ecoulement des pates et d'etudier les defauts generes durant l'extrusion au travers de filiere axisymetrique. Des mesures locales et directes de la vitesse a l'interface pate-paroi montrent que l'evolution de cette derniere est reliee a celle des defauts. La mise en evidence d'une evolution de la texture et des proprietes mecaniques de la pate au cours de l'extrusion oblige a tenir compte de l'histoire mecanique de la pate. L'analyse montre la necessite de prendre en compte la piezodependance sur le comportement rheologique en volume des pates et sur le comportement a l'interface. Elle a permis de proposer des mecanismes a l'origine des defauts d'extrusion qui permettent d'expliquer la morphologie des defauts dont l'evolution apparait liee a la texture anisotrope des extrudats et au comportement fortement plastique des pates d'argiles etudiees.

Resumo: E bem conhecido o amplo uso de materiais poliméricos e o proporcional impacto que eles causam quando são descartados no meio ambiente, especialmente os "commodities" como Polipropileno (PP) e Polietileno (PE). Isso tem preocupado os cientistas, que cada vez mais procuram desenvolver tecnologias para o reaproveitamento desses materiais. Uma das técnicas existentes e o reprocessamento por meio de extrusoras e injetoras, cujos processos, no entanto, tendem a degradar o material, levando a alteração em suas propriedades mecânicas e reológicas. Tendo em vista o contexto apresentado, foi desenvolvido um estudo no qual se avaliou a influencia da velocidade de rotação da rosca no processo de extrusão do polipropileno (PP) virgem e material reciclado, proveniente do setup durante a produção de canudos para refrigerante e rebarbas da fabricação de fraldas descartáveis, absorventes em que existe uma pequena quantidade de polietileno (PE). Observou-se sob quatro diferentes rotações, a saber: 40, 80, 120 e 160 rpm e um mesmo perfil de temperatura ao longo de uma extrusora monorosca. Apos o processo de extrusão, realizado sob as condições citadas acima, injetaram-se corpos de prova para analise de propriedades mecânicas, reológicas e térmicas. Constatou-se que as diferentes rotações estudadas provocaram alterações na deformação máxima de ruptura na tração, sendo que para o material reciclado, a rotação de 160 rpm apresentou a maior alteração dentre as demais rotações estudadas
Abstract: It's well known the broad use of polymeric materials and the proportional impact they cause when discarded in the environment, especially the "commodities" known as polypropylene (PP) and Polyethylene (PE). This has worried scientists, who search to develop technology to recycle these materials. One of these techniques is the reprocessing by extrusion and injection molding, the processes, however, tend to degrade the material, leading to alteration in their mechanical and rheological properties. Considering the context presented, it was developed a study where we evaluated the influence of rotation speed of the screw in the extrusion of virgin polypropylene (PP) and material recycled obtained from soda straws and disposable diapers's burrs, where there are a small amount of polyethylene (PE). It was observed four different speeds, namely 40, 80, 120 and 160 rpm carried out in one temperature profile along a single screw extruder. After the extrusion process, conducted under the above conditions were injected samples for analysis of mechanical, rheological and thermal properties. It was found that the different rotations cause changes in rupture maximum tensile strain. The recycled material processed at 160 rpm has presented the greatest change among the studied rotations

Abstract:
Extrusion of metal matrix composites (MMCs) is a very challenging one where in the bond between the reinforcement and the matrix alloy is crucial in getting high quality extrusions for industrial applications. In recent years researchers are focusing on developing aluminium based composites with metallic coated reinforcement to achieve good interfacial bonds to ensure smooth load transfer from the matrix on to reinforcement. However no information is available as regards hot extrusion of metallic coated reinforced MMCs. In the light of the above, the present work focuses on a systematic investigation on effect of extrusion process parameters on mechanical properties of Al6061-Ni-P coated SiC composites. From the investigation, it is observed that hardness, yield and ultimate strength of Al2014-SiC (Both uncoated and Ni-P coated) composites are higher when compared with the matrix alloy for all the extrusion ratios studied (4:1,5:1,10:1,15.5:1) at a given extrusion temperature. However, the ductility of composites decreases with increase in extrusion ratios. Further, heat treatment has a significant effect on the studied mechanical properties. Increase in extrusion temperatures at a given extrusion ratio has resulted in decrease in hardness and strength properties of both matrix alloy and developed composites.

Abstract:
Abstract. The mechanical properties of extruded AlMgSi alloys are affected by the applied thermo-mechanical parameters employed during the entire production process. In the following, the effect of different extrusion speeds and homogenization conditions paired with either air or water quenching, is examined on four different sets of rectangular hollow AA6082-T4 profiles. These profiles were fabricated and extruded under industrial conditions and selected cross sections of each profile were examined by optical microscopy to determine the microstructure and level of recrystallization. Uniaxial tension testing was used to explore the effect of homogenization conditions and extrusion cooling rate on mechanical properties. Tensile tests showed that the water-quenched extrusions had a higher yield and ultimate strength compared to air-quenched extrusions. Moreover, samples that had a recrystallized microstructure typically showed a larger standard deviation of mechanical properties, which may lead to product quality and consistency issues for metal forming operations. Overall, the present work provides a more in-depth understanding of how the selected thermo-mechanical parameters affect the resulting properties of such profiles. This can further contribute to expanding the potential for effective accommodation of extrusion parameters for zero-defect products.

Abstract:
Abstract. Cold forging processes, such as cold extrusion and in particular the Samanta process, provide a considerable potential for improvement in gears production. The method behind the Samanta process is based on the principle of cold extrusion in stacks. After partial forming of a workpiece, another workpiece is inserted into the die in order to eject a completely formed gear in the direction of the punch movement. Although this operating principle offers great potential for high-volume production, the industrial relevance of this process is limited by disadvantages such as high tool loads, limited gear accuracy and deformations on both face ends of the gear wheel. In order to overcome the technological challenges associated with the Samanta process, the die geometry was adapted. In this case the die operating surface was modified in terms of an extended forming zone length combined with an undercut in the tooth cavities of the die. In this paper the numerical results for this novel process regarding the correlations between geometric die parameters and resulting process data, such as punch force, contact pressure and die filling, are presented. The spline-based tool was methodically varied between one linear and two square (concave, convex) designs and was numerically evaluated using Deform 3D™ software.

Abstract:
As part of an ongoing effort to better understand the multiscale effects of fused deposition additive manufacturing, this work centers on a multiphysics, mesoscale approach for the simulation of the extrusion and solidification processes associated with fused deposition modeling. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum, and mass transfer, the solid-liquid–vapor interface is simulated using a front-tracking, level-set method. The results focus on the evolving temperature, viscosity, and volume fraction and are cast within a set of parametric studies to include the nozzle and extrusion velocities as well as the extrusion temperature. Among other findings, it was observed that fused deposition modeling can be effectively modeled using a front-tracking method (i.e., the level-set method) in concert with a moving mesh and temperature-dependent porosity function.
