Moldflow Design Guide Plastics Engineer's Guide to Product Design (Free eBook)

How to use this book?

The book has several chapters and appendices covering various design stages

Provides basic knowledge of injection molding process and plastic materials.

• The first three chapters describe how injection molding resins flow in a mold, mold and how molding conditions and injection pressure affect process.

• Chapter 4 discusses Moldflow design principles and how they relate to workmanship.

•Chapter 5 introduces finite element meshing method used by Moldflow and how meshing affects quality of analysis.

•Chapters 6 to 9 introduce design concept consisting of product, gate, track and cooling.

• Chapter 10 introduces concepts of shrinkage and warpage and how mold flow occurs, which is used to determine degree of shrinkage and warpage of a molded part causing warpage.

• Chapter 11 discusses design procedures for analyzing injection molded parts.

• Chapter 12 discusses main disadvantages of injection molded parts.

• The last four appendices discuss basic operations of an injection molding machine, process control, various standard injection molding processes, and plastic materials.
