Molds for Casting Vehicle Parts
Casting metals and alloys makes most of the parts for vehicles. To shorten the time to market and get a satisfied quality new design approach have to be involved. New CAD based technologies are giving an opportunity to make molds faster and cheaper with a high quality than previously using classical methods. In this paper master mold design process including decision about materials is presente...
متن کاملAIR PRESSURE SIMULATION IN CASTING MOLDS
During mold filling, molten metal can only advance as quickly as the air inside thecavity is expelled. In this work an analytical model describing air flow is developed based on aincompressible flow theory. Air pressure has serious effects upon the filling behaviour such assurface profile and filling time. In this work a new mathematical model is proposed for calculationthe air pressure during ...
متن کاملCasting inorganic structures with DNA molds.
We report a general strategy for designing and synthesizing inorganic nanostructures with arbitrarily prescribed three-dimensional shapes. Computationally designed DNA strands self-assemble into a stiff "nanomold" that contains a user-specified three-dimensional cavity and encloses a nucleating gold "seed." Under mild conditions, this seed grows into a larger cast structure that fills and thus ...
متن کاملComputer-Aided System for Multi-Cavity Die-Casting Die-Design
Die-design for the die-casting process is a time consuming and complex activity that requires domain knowledge and vast experience of the die-designer besides information about manufacturing resources, part geometry, delivery time and cost preferences, etc. Complexity of the die-design activity further increases in case of a multi-cavity die. Currently available die-design systems lack in the l...
متن کاملApplication of TPM indicators for analyzing work time of machines used in the pressure die casting
The article presents the application of total productive maintenance (TPM) to analyze the working time indicators of casting machines with particular emphasis on failures and unplanned downtime to reduce the proportion of emergency operation for preventive maintenance and diagnostics. The article presents that the influence of individual factors of complex machinery maintenance (TPM) is ...
