Die casting is forcing molten metal into a mould with high pressure. has two dies namely moving die and fixed where the one will move over die. majorly used for high-volume production. This paper focused on physical phenomenon of (moving die) using different alloy materials variable material chemical compositions. The numerical analysis carried out process to determine crack formation zone by t...

Abstract Zum Titelbild: Kranbau Köthen erhielt vom Stahlmagnaten Thyssenkrupp Steel Europe AG den Großauftrag, einen Pfannentransportkran in Zwei‐Träger‐Ausführung mit 40 m Spannweite und einer Tragfähigkeit von 390 t zu bauen. Für Kranbauspezialisten war das Projekt eine enorme Herausforderung, insbesondere was die Logistik Fertigungsabläufen, Transporte Montage derart schwerer Bauteile betrif...

This present work is aimed to optimize the machining parameters and study effect of powder mixed dielectric fluid on EDM process. TOPSIS method optimization adopted identify optimal parameters. HCHCr die steel preferred as material. Ni, Zr Ni+Zr were selected inclusion in due hard ductile nature. L9 array Taguchi DOE perform experiments with like peak off time, pulse time current. revealed that...

Metal forming processes, compared with machining ones, reduce production steps and increase manufacturing speed in addition to saving raw material. In this paper, forming process of column of a steering mechanism is investigated by finite element analyses and experimental tests; and optimum die design parameters are found. Forming process parameters including die opening angle, bearing length, ...

in the present work, the effects of changing punch and the die radius on several process parameters involved in deep drawing of aisi 304 steel have been studied. deep drawing process of a cylindrical cup was simulated and analysed by numerical modeling. the results were compared with those of obtained from a serie of experimental cupping tests. the comparison shows that: maximum drawing force d...

In the present investigation, various kinds of textures, namely, unidirectional, 8-ground, and random were attained on the die surfaces. Roughness of the textures was varied using different grits of emery papers or polishing powders. Then pins made of Al-4Mg alloys were slid against steel plates at various numbers of cycles, namely, 1, 3, 5, 10 and 20 using pin-on-plate reciprocating sliding te...

Deformation of the material during cyclic expansion extrusion (CEE) is investigated using upper-bound theorem. The analytical approximation of forming loads agrees very well with the FEM results for different amounts of chamber diameter, friction factor and also for lower die angles. However, the difference between analytical and numerical solution increases at higher die angles which are expla...

In order to optimize the strength-toughness matching of auto body components. Taking B1500HS steel as research object. The influence die temperature on microstructure and properties was studied by hot stamping tests flat die, mechanical observation tests. study shows that is not sensitive below 250°C. When 20–250°C, tensile strength above 1400 MPa, while plastic-toughness poor; 300°C, begins ge...
