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.
