This great little app contains the same information as Routsis Training’s printed “Scientific Molding Pocket Guide.” We have always found the sections on plastics materials and their properties to be particularly useful. But unlike the printed version, the app includes the ability to bookmark and make notes on each section — and features a clickable Table of Contents. The search function is also really handy. Routsis has also added some interactive calculators for quick standards conversions, such as millimeters to inches and Celsius to Fahrenheit. This digital “Pocket Guide” is a must-have for injection molders.
