Here is a book that brings the art of plastic injection molding to the home shop level. Working with plastics can be a fun and profitable hobby. If you have ever wanted to produce custom made plastic parts or just want to know how it’s done then this book is for you. Included are complete step by step instructions on how to build a small inexpensive table top injection molding machine capable of injecting up to 1/2 ounce of plastic into a mold. Sources for plastic will be those things normally thrown away. Stuff like plastic milk jugs, soda pop bottles, plastic oil cans etc. You will learn the basic principles of injection molding and how to design and make your own molds. Begin by making a simple mold to test the machine. Then a mold for a plastic knob that will be used on the machine. Progress to a mold for a small plastic container with a snap lid. It won’t be long before you will be creating new products of your own design. I’ll even show you how to cast replacements for broken or missing plastic parts. Just think of the possibilities. And the finished items you make will turn out so nice and look so professional that it will be hard to believe you made them yourself. Construction is simple and straight forward, but it will require basic metal working knowledge and access to a metal lathe and a drill press along with other hand and power tools associated with metal working and machine work in general.
The goal of the book is to assist the designer in the development of parts that are functional, reliable, manufacturable, and aesthetically pleasing. Since injection molding is the most widely used manufacturing process for the production of plastic parts, a full understanding of the integrated design process presented is essential to achieving economic and functional design goals. Features over 425 drawings and photographs.
