The four presentations will cover the latest advancements in metal casting
simulation research and practice

PARIS --(BUSINESS WIRE)--18.03.2010--

CastExpo’10, sponsored by the American Foundry Society (AFS) and the North
American Die Casting Association (NADCA), is the largest trade show and
exposition in North America for metal casters. It will be held on March 20
to 23 in Orlando, Florida, USA.

The presentations, given by ESI, will cover four different facets of metal
casting simulation and will be given during the diverse congress technical
sessions throughout the 3-day event by Sam Scott, ESI’s Casting Lead
Engineer.

1. The first paper entitled ‘Transition to No-Lead Copper’ will be
presented on Saturday, March 20 at 2pm during the ‘Copper Alloy’ session -
S320C.

During the “Copper Alloy” session, in addition to ESI’s presentation on
re-engineering with solidification modeling, two foundries will present
case studies of their use of solidification modeling to ease their
transition from leaded to non-leaded alloys.

2. The second paper entitled ‘Core Blowing Simulation’ will be presented on
Sunday, March 21 at 3:45pm during the ‘Engineering’ session - S320C.

As casting knowledge continues to expand, the percentage of scrap due to
mold preparation will continue to increase, establishing a need to
understand the creation of the mold components. ESI’s QuikCAST numerical
simulation software provides a tool for understanding and predicting the
core blowing process. By treating the sand injection as a non-Newtonian
flow, much insight is gained into the core manufacturing process, allowing
engineers to properly design the core box, venting locations and sizes, and
injection pressures. The paper discusses the analysis methodology and
trials of two very different cores with experimental validations.

3. The third paper entitled ‘Aluminum Microstructure/Heat Treatment’ will
be presented on Monday, March 22 at 8:30am during the ‘Aluminum’ session -
S320B.

A comprehensive numerical model has been developed for the calculation of
the final microstructure and mechanical properties of aluminum casting
alloys after heat treatment. After specifying the alloy chemical
composition, solidification process, and heat treatment parameters, the
model predicts the microstructure and potential defects through various
stages of the component lifecycle: casting, solid solution heat treatment,
and artificial aging. The calculation is chained such that the resultant
microstructure of the previous event, such as casting, is used as the
initial condition of the following event, ensuring the tracking of the
component history and maintaining a high level of accuracy across
metallurgical stages.

4. The fourth paper entitled ‘HPDC Optimization’ will be presented on
Monday, March 22 at 2pm during the ‘Die Casting’ session - S320E.

HPDC foundries currently rely on experience, trial-and-error or computer
simulation to help determine working process parameters for manufacturing
their cast parts. However, a “working” process is not necessarily the
“ideal” process. Casting parameters such as cycle time, shot profile,
cooling line temperature and flow rate, and spray thickness may be
optimized to determine a robust process with maximum productivity. In this
paper, ESI’s casting simulation software ProCAST is used to demonstrate new
functionality which automatically optimizes the casting process parameters.
The demonstration utilizes a legacy casting design, simulates the casting
process used at the foundry, and then automatically optimizes the casting
process by varying fast shot speed, cycle time, cooling and spraying
parameters within a given “realistic” process window, with a goal of
producing a quality part in a minimum cycle time.

Delegates will also be able to find out more about ESI’s Casting solutions
by visiting ESI’s booth #1413 in the exhibition area.
