The first three case studies are pertaining to a very critical part - a crank case used in an automobile compressor application. During the production process, the die was found to wear very frequently resulting in high rejection rates

This case is a continuation of the previous one, in terms of the design improvements as suggested by CRP. Upon close examination of the design and the part drawing, it was found that the general radius was called for as 1.6 mm, whereas in the design
The die designer is constrained by the part design as it is an end-user requirement, over which he has very limited or no flexibility. Generally, the design of an HPDC die starts with part modeling, followed by the shot design.
The first case study was one of the earliest applications for the author in terms of simulation. One of the customers came with a RFQ for a group of parts for a compete assembly, mostly with HPDC except one part.
This case is also a continuation of the previous two, in terms of cause and effect correlation and acceptance criteria. Porosity was always an issue since the beginning of the development of this part, as it is needed to be pressure tight.
This is a general case of a Flow simulation and its application and uses in a day to day design of the HPDC design in terms of the following approaches: Flow Solidification Thermal Die Cycling Thermal
This case study is a simple example of minimizing the runners and overflows of a die casting shot design of an alternator bracket casting, thereby reducing the cost. Figure 2a shows the shot design before optimization.
Reducing the cost is the need of the hour, and the design simplification is one of the effective means. This case is an example of the same where as the customer requirements in terms of volumes have increased and adding capacity at this juncture should be the last option. Hence we explored the possibility of […]
Automobile alternator is an assembly of Slip Ring End (SRE) Bracket and a Drive End (DE) Bracket as the casing and the other parts are housed inside them. This customer was complaining of the binding
