Plastic Injection Molding Attachment for a Drill
but that's a substantial volume that can be used to make many kinds mechanical components, parts for models, and (knowing you) obscene sculptures.
You'll get a material list, drawings and details on making the support posts, the nozzle, the injection cylinder sub-assembly, the ram, and the ram sub-assembly. You'll be shown how to wire up the controls, how molds are made, how to identify recyclable plastics, use the temperature controller, and start injection molding.
You get the usual Gingery quality: photos, drawings, detailed text, suppliers, hints and tips, and all the rest that has made Gingery Publishing world famous (and that is no exaggeration)!
You oughta have copy. Sorry, no details on using this versatile device to make chewing gum, worm capsules for your dog, or exploding suppositories for your mother-in-law. But, geez... you oughta come up something more original than that, anyway.
"For the most part, plastic injection molding today is done with complex automated machinery turning out many thousands of items per day. But what if you are an experimenter, inventor or hobbyist and you just want a few parts made?
We have attempted to answer that question for you by providing these plans for a small hobby size injection molding machine capable of molding slightly more than 1/2 ounce of plastic. (.59 ounce to be exact)
This amazingly compact machine is designed to be used with a floor model style drill press having a minimum spindle travel of 3". Thus, we refer to it as an injection molding attachment for a drill press.
The unit itself measures approximately 12" long x 1-3/4" diameter at its widest point and weighs just 3 pounds. In operation, plastic is melted in the injection barrel of the machine by two 1/4" diameter x 2-1/2" long cartridge heaters. The temperature of the barrel is accurately controlled by a digital temperature controller and thermocouple arrangement. The force required to inject the plastic is provided by the feed mechanism of a drill press. Construction is simple and straight forward, but it will require basic metal working knowledge and the ability to operate a metal lathe and a drill press along with other hand and power tools associated with metal working and machine work in general. Here in this booklet you will receive detailed step by step instructions along with photos and drawings showing how to build your very own injection molding attachment for a drill press...."
