In this post we are going to discuss how it is possible to reduce components weight while maintaining their functionality through the use of co-design.
The main die casting defects which occur during die casting can be divided in categories related to different phases of production process: die casting, pre-finishing, machining operations and surface finishing. In particular in this article we are going to analyze defects related to the first category: die casting.
To predict shrinkage porosity and other defects, simulation is increasingly used nowadays, as these software require less development cost and time than experiments. Only some specific simulation programs, however, take into consideration the effect of back pressure in the cavity in die-casting. In this article we are going to discuss: what is shrinkage porosity, causes of the defect and how to avoid it with simulation.
In high pressure die casting industry both suppliers and customers are always looking for the best solutions in terms of part load, costs and times for development and manufacturing processes.
The concept of die casting mould design concerns the design of the mould but in general it defines the entire process of die casting. It’s a phase of the product industrialization that has clear characteristics to avoid many defects: for example cold laps.
Hot chamber hpdc is a die casting process in which high pressure is used to force molten metal through a mould. The use of pressure let the metal flow through the die and leads to great qualities of castings especially when a perfect surface is needed. In hot chamber hpdc, the supply of molten metal is an integral part of the casting machine for the manufacturing operation.
