This book is the first in a series aimed at assisting and making suggestions in the Plastics Injection Moulding arena. It gets down to the Meat and Potatoes of this arena or basic level, the core understanding if you will. I believe to firmly get a hold on teachings being made in this arena we must fully understand the reasoning behind these teachings. I don't think it's acceptable to just step you through a process without a full in-depth explanation on Why that particular step is taken. This first volume takes into consideration some basic elements for the diesetter and technician, this is to give an understanding on what is to come in further volumes directed towards Diesetting, troubleshooting and die-trialling.
