CAE Technology

5

> 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
