Secrets of Building a Plastic Vacuum Forming Machine, by Vincent R. Gingery, published by Dave Gingery Publishing, Rogersville, MO, 1999. 5 1/2 x 8 1/2 paperback, 106 pages, ISBN 1-878087-22-3 Please note this book is new, not used. Discover why vacuum forming is considered one of the most versatile of the plastic thermoforming processes. After covering basic plastic technology, you will learn how to make your own molds and use them to quickly form flat sheets of thermoplastic into intricate shapes with incredible accuracy. You will be able to fabricate unusual signs, plastic containers, decorative objects, model car and airplane bodies and more! After building and using your own vacuum forming machine, you will be capable of designing your own masterpiece projects! The secrets you need to build a large professional quality vacuum forming machine are here. Learn step-by-step how to design and build your own fully self-contained machine capable of molding thick sheet plastic with negative molds - a type of mold not often used in other machines. By building the platen attachment you can expand the capability of your machine to use positive molds as well. Simple angle iron construction and clever design make this a rewarding project to build. It has a unique clamp frame that works very well and the adjustable work surface (platen) is a real asset. The machine has a 12" x 15" forming area, and Gingery has formed ABS plastic up to 3/16" thick with it. Everything required to build the machine is easy to find except for the 120 volt heating element. It's an oven replacement element, and will probably cost around $30.00 plus shipping. Best of all, you will save money. By investing a few dollars and a bit of labor, you'll end up with a machine, which if purchased, would cost far more! And when you start turning out products to sell at flea markets, craft shows, and hobby shops, you'll more than recover the small construction cost. And your professional quality forming machine will be on wheels making it easy to move when not in use. Your machine will operate on a standard 20 amp 120 volt circuit, and it features an adjustable work surface to hold a variety of molds and sheet sizes. Your machine will use a dual vacuum source being either an air venturi pump or electric vacuum pump. Only $12.99 through Harbor Freight and the air venturi pump pulls 4.2 cfm per minute taking about 4 minutes to pull a 25 hg vacuum on my two 11 gallon tanks. Not too shabby for the price. In order to use it though, you need to have an air compressor capable of maintaining 90 psi.. The other and better alternative is an electric vacuum pump. The electric pump I have pulls 6 cfm taking about 2 minutes to pull a 25 hg vacuum. Although twice as fast, the electric pump costs close to $300.00. The secrets are here. Use them, add some imagination, and you will be amazed at what you'll be able to manufacture quickly and inexpensively. Description copyrighted 2002.
