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’.


  • 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.


Mold Temperature

Results & Reporting
