Inspired by the Spain guys use of the car jack for the injection, I started designing a combo injection/compression molder.
think of a shop press.
We can change to either a piston or a mold plate using plumbing fittings.
The bottom half of the machine is the injection. (sorry you will have to stoop down a little to use it)
the top half is the compression molder. We have a removable plate for the compression.
Also the frame is changed to square tubing and the tubing acts as a linear guide to keep the parts from wobbling. The jack by itself can wobble without guidance.
Pictured is the compression only machine.
Next version, change from U channel steel to square tube. the tube will be the frame and a linear guide.
