Casting solidification brings to the shrinkage in the liquid state, solidification shrinkage and shrinkage in the solid state. Recently, technologies of die and gravity casting have increased the number of highly functional castings, which have been characterized with the very complex geometry. due to the different wall thickness in these castings, as well as the high solidification rates, prem...

High-Pressure Die Casting (HPDC) is one of the major production processes automotive industry, widely used to manufacture geometrically complex nonferrous castings. The mechanical strength and microstructure HPDC-manufactured products changes with variation in several process control parameters such as injection pressure, molten temperature, 1st 2nd stage plunger velocity, cooling etc. Since th...

Induction motor manufacturers have long known that substitution of copper for diecast aluminum in the rotor squirrel cage would significantly reduce motor losses and improve the electrical energy efficiency. Aluminum is readily die-cast to produce the complex squirrel cage within and around the iron laminations of the rotor. Copper is much more difficult to die-cast due to its high melting temp...

Aluminum alloys show a low weight, relatively high specific strength, good corrosion resistance in neutral environments and high electric and thermal conductivity. It makes them of interest for production of various functional components in aerospace and automotive industry. Wrought alloys generally have good formability and they are processed by common technologies, such as extrusion, forging,...

Die-pattern technique is presently the most prevalent in use as a general method of constructing inlays, and crown and bridge work. A wax pattern is prepared on a stone die and taken out to be invested and cast. This method and process of taking wax patterns out of the die occasionally causes deformation or damage to patterns due to handling or the properties of the wax itself, and this affects...

Die corrosion has been a concern during aluminum alloy die casting. The casting parameters play significant role in causing corrosion, such as the temperature of melt and working time. In order to study effect time on dynamic behaviors, SDHA steel was stirred molten ADC12 at 650–800 °C. morphology product were investigated through X-ray diffraction (XRD) scanning electron microscope (SEM) obser...

Based on the 3 factors and levels orthogonal experiment method, compositional effects of Mg, Si, Ti addition microstructures, tensile properties, fracture behaviors high-pressure die-casting Al-xMg-ySi-zTi alloys have been investigated. The analysis variance shows that both Mg Si apparently influence properties alloys, while does not. mechanical are comprehensively influenced by amount eutectic...
