But most plastic components these days are created by huge, expensive plastic injection molding machines.
Molten plastic is forced under enormous pressure into intricate molds.
On the surface it appears to be a technology well beyond the realm of the home shop. At last, here is the book that simplifies this technology making it possible for you to inexpensively injection mold small parts from common recycled plastic. Although a half ounce may not appear to be much plastic, the truth is, that it is more than enough to produce many small useful items. Best of all you'll be molding with plastic recycled from milk jugs, soda pop bottles, plastic oil cans, and more. Your raw materials are free and plentiful.
