How to organize pressing of rings with thin walls?

First – even if we do not take into account the fact that there will be a hole inside your tablet, but simply consider pressing a tablet with a diameter of 2.2 – 4.5 mm, the question of feeding the powder inside such a hole becomes acute. This is possible only with some exceptional bulkiness of the powder, or by force. The powder will not flow into such a hole by gravity. Now we have the same problem, but we need to feed the powder evenly around the rod, which forms the inner hole. This is a difficult task.

Whatever the task, MINIPRESS is ready to take it on. We are more powerful than many competitors and our service is much more convenient. We provide our customers with impressive terms and amazingly fast turnaround times. Our specialists use the most advanced technologies in the world to select various equipment. We have everything you need for modern production of any level. And even more.

Technical specifications

Further, if we take for example the maximum diameter of the finished tablet in 4,5 mm, and the diameter of the inner hole is 1 mm, it turns out that the punch wall is 1,75 mm!!!!. A lot of questions arise at once – where and how to make hardening of such a tube! How to grind it at all! And there are no guarantees that at the first pressing this tube will not burst. And it will. People break punches 20-30 mm in diameter.

Additional information

Even if we assume that we (or rather you) managed to feed the powder into such a die and press such a tablet, the thickness of such a ring is 1.5 mm, and the walls are 1.75 mm – how to move it so as not to break it? So pressing such tablets is possible only in an extrusion press, where the powder is pressed through a hole with a screw, inside of which there is a rod that forms the inner hole. This equipment is often found in powder metallurgy.

There is such a press in Minsk in one place, and another USAn company asked me to find someone who would buy or give orders. On such presses it is possible to form tubes of your size. The only remaining question is how to cut them into the rings you need.
