    Do you want to know how to build your own plastic injection molding machine?  If so, then this article will set you on the write path.

    Why Build a Plastic Injection Molding Machine?

    Creating with plastic can be fun and can be a profitable hobby as well. 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.

    However, the book Secrets to Building a Plastic Injection Molding Machine simplifies this technology making it possible for you to inexpensively injection mold small parts from common recycled plastic.

    What is inside the Book?

    Secrets to Building a Plastic Injection Molding Machine shows complete step-by-step instructions revealing the secrets of building a small inexpensive tabletop injection molding machine capable of molding up to a half ounce of 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 bottles, plastic oil cans, and more. Your raw materials are free and plentiful. You will learn the basic principles of injection molding and how to design and make your own molds.

    You will start by making a simple mold to test the machine. Then you will mold a plastic knob for the machine itself. Next, you’ll progress to a mold that creates a small plastic container with a snap lid.

    The Joys of DIY Plastic Injection Molding

    Before long you will be creating new products of your own design. You will be able to cast replacements for broken or missing parts, or you can make copies of plastic components. The possibilities are endless.

    The moldings are incredibly professional in quality. Your friends will never understand how you were able to do it. Injection molding is a technology that has given us an incredible standard of living. Here are the secrets that will allow you to put this technology to work in your home shop. Build a molder, and explore a whole new technology today.

    If you have this machine, and the others in the Gingery build your own metalshop series there really isn’t anything you can’t build.

    DIY: Plastic Rope

    I have the cutter pictured but in this video I try to save money and make my own bottle cutter to make plastic rope.

    The first time I saw this it was from one of those crazy Russians.  I think all their hacking videos have confused people politically, but this hack works pretty good.

    The idea is that you can use a razor and a jig to cut strips of plastic from a PET plastic soda bottle.  These strips are long threads of DIY plastic rope.

    The plastic is very strong and will shrink under heat.  This makes it excellent for repair and lashing projects.

    The video above shows my DIY cutter, but I find my purchased one works better.

    Now, I do make a percentage from a sale as an amazon affiliate but I do want to tell you that the jig sold in the picture is pretty simple to make and at $40.00 you can click onthe link and look at the bottom of the amazon page and find other plastic rope cutters for much less.

    This is a concept that once you understand the process a thinking person can easily figure out other ways of accomplishing the mission.

    The goal is to always be able to make string from something that normally just fills up the landfill.
