My latest pneumatic injection machine
I’ve been working towards a more powerful injection machine for a while. This is my latest attempt.
Looks great, what force does the cylinder produce?
The cylinder has a 5 inch bore and my air compressor is capable of about 140 psi so……..
radius * radius * pi * 140 = force
about 2,750 pounds maximum.
We want to upgrade our injector to have pneumatics. Do you have the details on the pneumatic cylinder you used? How large of a volume tank do you need on your compressor for that cylinder? Any lessons learned that you can share with us before we start? Thanks!
My current machine uses this 5″ bore cylinder:
I’ve also built a machine using a 4″ bore cylinder:
I’ll upload an image of that machine.
The smaller cylinder should be adequate for most parts. Small, detailed parts made out of HDPE require a lot of pressure, that’s what I built the larger machine for.
My air compressor has a 30 gallon air tank.
Machine with 4″ bore cylinder.
