KTFF solves injury troubles! (Automatic welding joint)

KTFF solves injury troubles! (Automatic welding joint)

Ihara made a joint that is a little innovative with the obvious "certain thing," so that it doesn't hurt your hands and the heater doesn't tear.

When assembling semiconductor manufacturing equipment, we often hear concerns like, "It's dangerous because the gas piping can injure your hands or gloves," and "Wrapping a heater around the gas piping can cause it to tear." Therefore, we at Ihara sought to solve this problem by asking, "What causes hand injuries?" As a result, we developed the automatic welding joint KTFF, which does not injure hands. By changing the manufacturing process, we were able to reduce issues such as injuries to hands and gloves and tearing of heaters.
