Book Description
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 inches. Thus, we refer to it as an 
injection molding attachment for a drill press. The unit itself measures
 approximately 12 inches long x 1-3/4 inch 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 inch diameter x 2-1/2 inch 
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. A material list
 is provided. Suppliers are also identified and you will also receive a 
basic introduction to plastic injection molding in general.   Before you
 know it, you will be creating plastic products of your own design. And 
you will have the capability to cast replacement parts, or even make 
copies of those hard to find items. The possibilities are indeed 
endless.
