Need Help building a injection machine :)
Im building a injection machine (exactly the same one of the main video), but i can’t find the specifications of the tubes (the one that presses the plastic nor the one you heat). Could you help me?
Can you tell me the diameter of each tube or how mach is the difference in mm from each tube?
Do they both also have to be from steel or you would recommend a different material for each?
There should be drawings and a bill of materials in the download kit. The important thing is what is available in your area. The inside one (piston) is usually a solid rod, though if you find a way to close off the end and the walls are thick enough so it does not bend, you could make a tube work. The outside tube and the band heaters you can find need to be consistent in size. As the instructions say, check the outside tube to make sure it is smooth (no weld seam). You could use aluminum if you have a good way to attach sturdy mounts.
Thanks for the info! Today I finally found a good steel piston and tube 😉
