> CAE: Computer-Aided Engineering – a kind of software and technology that simulates and analyzes the
complicated injection-molding process in the computer
– permits quantitative mold design according to rheological, thermal, and mechanical consideration
– trouble-shooting of existing process/design
> Virtual visualization – Realize the significance of variables and
quantifiable effects of changes
– Reduce number of physical experiments
What is CAE in Injection Molding?

> CAE is an idealization of real world process
> Reliability of CAE analysis depends on:
– Physical Model
– Numerical Methods
– Material Parameters
– Geometric Model
– Engineering Knowledge and Skill of the User
> GIGO Principle:
– Garbage In, Garbage Out
Concepts in Application of CAE
8
> Good direction to revision for existed mold/product design.
> To realize the cause of problem for trouble-shooting
> To accumulate knowledge
– Make as Know-how
– Become the design criteria
Benefits of CAE Technology
