Overview of Runners, Gates, and Gate Positioning. Rheology and Melt Flow in an Injection Mold. Filling and Packing Effects on Material and Molded Part. Gate Positioning and Molding Strategies. The Melt Delivery System. Filling, Melt, and Product Variations Developed in Multi-Cavity Molds. Managing Shear-Induced Melt Variations for Successful Molding. Cold Runner Molds. Hot Runner Molds. Hot Runner Flow Channel Design. Hot Runner Drops, Nozzles, and Gates. Thermal Issues of Hot Runner Systems. The Mechanics and Operation of Hot Runners. Process of Designing and Selecting a Runner System (Gate and Runner) – A Summary. Troubleshooting.


The first book to shed light on the critical role the melt delivery system plays in successful injection molding has received a major update in its third edition. This best-selling book will give you an immediate leg up by reducing mold commissioning times, increasing productivity, improving customer satisfaction, and achieving quality goals such as Six Sigma.

How do you determine the optimum design of your runners and gates? What type of runner system (hot or cold variations) do you use for a specific application? How do you identify molding problems generated by the gate and runner vs. those stemming from other molding issues? What should you consider when selecting a gating location? The Runner and Gating Design Handbook will give you the means to get to the bottom of these issues as well as provide specific guidelines for process optimization and troubleshooting.

Highlights among the numerous new updates include coverage and analyses of critical shear induced melt variations that are developed in the runners of all injection molds, expanded content on hot runners, and a new subchapter on injection molding process development.
