CAST DESIGNER FOR INVESTMENT CASTING
Casting Designer software from C3P Engineering
Software International can handle both High Pressure
as well as Low pressure casting simulation. Cast
Designer for Gravity casting supports, Investment
casting.
CAST-DESIGNER FOR Investment Casting
Cast-Designer for investment casting is a quick
casting design and analysis tool based on upfront
design & analysis technology. The core of the “upfront
design & analysis technology” is to allow engineers
to conduct fluid flow, heat transfer and solidification
analysis by the assistance of combination of expert
system and CAE technology, it helps engineers to
make a “Right” engineering decision in the early
design stage of a project . Upfront design & analysis
technology has already been becoming a very important
role in main stream design process.
With Cast-Designer, users can optimize a casting
design by detecting the part features with potential
metal flow and solidification problems, evaluating
gating and pouring system design alternatives in
the early design stage. Even a novice with limited
experience in simulation can easily undertake the
design setup in very short period of time. In other
word, Cast-Designer can help the industry to achieve
the target of ‘Time to Market’.

Benefits
- Perform design and validation in very early
stage to save cost and time to maximum
- Make better design and compare more solutions
thanks the quick modeling and simulation technology
- Express part analysis tool helps communication
with customer
- Improved design quality and enhance designer
knowledge
- Generate industry design database
- Short learning curve, easy to use
Gating System Design for Investment Casting
Gate System Advisor
- Cast-Designer is an expert system,
with KBE technology for Investment casting process.
- It has half century knowledge,
and experience of investment casting process, and it
can provide complete guide line help help
to the designer.
- The gating system advisor, is one
of the most useful wizards in Cast-Designer.
With such advisor, the designer can
get, the filling time, and inner gate
section area, based on the casting weight,
or volume, and feature thickness of
casting part. Then the user can adjust
the numbers, and section area of runner
and sprue runner.

Main Tree / Runner Design
- Main tree design, is a major feature,
of investment casting. The parts will
attached to the main tree, and the pouring
system, also base on the main tree.
- Cast-Designer is the sole system,
to guide investment casting system design,
in the market today, The gating system
design modulus, could design, any complex
casting system, in full parametric method.
- Riser, inner gate, runner, main
tree runner, and chill could be designed,
in Cast-Designer. The typical main tree
types, have been build in, the system
to simple use.Cast-Designer also support,
user defined template, and with flexible
function, to import and export, the
template file.

SMART Designer for Runner
- Part Layout design is necessary
for investment casting to increase
the production rate.
- The smart Designer function,
is a niche feature in Cast-Designer.
It is the build-in knowledge database
with tens of year industrial experience
to balance the yield ratio and casting
quality, both filling and shrinkage
porosity are taken account.
- The concept is, we will use
the main runner, and pouring cup,
to make the compenstation of metal
shrinkage, in the solidification
process. The user only need to input
the total casting weight, and select
the close dimension, to the part
geometry, and layout boundary size,
then the system will generate the
main runner, automatically.

Radiation, View and Shadow Factor
- For high temperature process like
investment casting, the heat radiation
must be taken into account.
- The effect of shell and enclosure
is important in radiation calculation,
Cast Designer has tools to include these into the model setup easily
- View factor and shadow factor may
change the solidification result. It can be specified in the Cast Designer Model Setup.

Design Capability
- Build in KBE system to support casting system
design, such as riser, feeder, gate, runner,
sprue runner, pouring system, chill etc. All
components of casting systemcould be designed
in full parametric mothod.
- Build inmain tree designwith ‘smart design’
advisor
- Dewax checking
Model Setup
- One windows page to setup casting process,
boundary condition and control parameters for
flow, heat transfer, radiation and solidification
simulation
- With rich material data in database, more
than 140 types material special designed for
investment casting
- Built-in material converter for different
country standard.
- Pre-defined template for investment casting
process
- All conditions and parameters could be save
as template file for future usage

Solver Technology
- Based on Finite Element Method (FEM) technology
- Fluid flow calculations are described by
the full Navier-
- Stokes equation and couple to thermal analysis.
- Pre-defined template for investment casting
process
- Simulate the physical phenomena and mechanical
behavior of metal filling, solidification and
cooling process, such as temperature, velocity,
pressure, liquid/solid factors etc.
- Special solver for radiation view factor
calculation.
- Innovation technology to speed up simulation
in express mode, one hour to two hours for most
cases.
- Submit job to solver in directly and batch
queue mode
- Both 32 bits and 64 bits solvers available
- Parallel computing technology for big or
huge model
- Mechanical module for both machanical &
thermal stress and deformation.
