Simulation in Injection Molding

The purpose of this book is to help increase the reader’s knowledge of simulation, which will increase the ability to detect and avoid molding errors at an early stage. Readers should learn to draw the right conclusions from the simulation results and to develop their own solutions.

In plastics technology, a wide variety of computer programs are used for the design and optimization of plastic molded parts and for mold design. These programs calculate the filling process, the holding pressure phase and the cooling phase of the molded part in the mold. The results include pressures, temperatures, weld lines, and voids. The shrinkage and warpage behavior of the molded part can also be predicted. Understanding and interpreting these simulation results is not trivial, although they are colorful representations with numerical values. Regardless of whether one has many years of experience as a designer, mold maker or injection molder, or whether one is in training or studying, simulation is becoming increasingly important. For this reason, experts who know how to use these programs correctly are increasingly sought on the market.

This book is intended to help increase the reader's knowledge of simulation, which will increase the ability to detect and avoid molding errors at an early stage. Readers should learn to draw the right conclusions from the simulation results and to develop their own solutions.
