Fundamentals of CAE 

Injection molding analysis can predict the orientation of fiber reinforcement (fibrous filler) in injection molding. This article explains what fiber reinforcement orientation is in injection molding and the importance of understanding the orientation.

In this issue of injection molding simulation using CAE, we will introduce an example of application to gas-assisted injection molding.

Injection molding analysis is a valuable tool for predicting molding defects at the design stage and taking countermeasures in advance. In this part, we will introduce various types of molding defects and analysis evaluation items that can be utilized for proactive countermeasures.

We will explain the output results of injection molding analysis and how the obtained information can be used in product/mold design and molding process.

In this part , we will explain the material data (rheological properties, thermal properties, PVT properties, etc.) used for injection molding analysis.

From the 4th to the 9th, we will sequentially introduce the injection molding simulation from the material data to be used to the specific application contents such as molding defect countermeasures. In this article, we will focus on injection molding.

The purpose and application of each analysis field will be explained, and typical software and software used at Asahi Kasei will be introduced.

We will explain the differences in the material properties of plastics and metals in an easy-to-understand manner, and introduce the points to be considered in CAE analysis of plastics.

We will introduce basic knowledge of CAE and the key points of the finite-element method (FEM), which is commonly used in analysis.
