There is a powder feeder named “micro feeder” using the principle of feed principle of local fluiding type in TSV’s former products. It feeds powder that has low fluidity to goal 100mmg-1g/min. through plastic tube with 4 millimeter in diameter. This feeder was produced for microplasma spray apparatus at the beginning, it makes thin film about 10micron by using powder about 1 micron. Although we were wondering it deserves or not to be named “micro plasma spray”, new micro feeder is true to name.

The feed principle is surface tracking as the same as the powder feeder “AM series” that is active at present. Talking of image, the nozzle absorbs powder is just like a pipette which is used for picking up an ovum at the biological experiment. The tip of nozzle approaches to surface of powder with using high accuracy positioning technology , it absorbs particles of powder one by one exactly, and it jets them to goal. If the goal was in the plasma jet, particles of powder one by one would dissolve rapidly and stick on the small pieces of target, micro jet would be into action.

This is definitely not a dream, this is present a fine target that can be easily carried out with TSV’s present technology.

Liner powder spray apparatus

We had a inquiry over year ago from one company in Kansai district about liner powder spray apparatus powder which can infiltrate and disperse powder into the surface of steel coil before it dries during winding steel coil from a bath. The idea we proposed at that time didn’t reach to bring into production, but we really hope to put the plan into practice if we get half a chance soon.

The point of liner powder spray is keeping constant density while jetting powder along the course. In that case, generally you may think to expand powder and carrier gas brought to near the goal with using the round tube by flat nozzle as a cleaning thing. But in this way, keeping constant density is difficult. In TSV, constant density is being kept from when powder was absorbed, powder passes through the way as keeping the same shape as the nozzle section, and it is jetted with keeping it.
We believe that our technology will work out various solutions.
