Our entry, a steel case frame, used to
be considered a difficult product to commercialize from the standpoint
of productivity and other problems. Because its casting structure
requires machine work in the production of most parts, it is difficult
to manufacture using sheet metal processing.
Given this, we ventured to take an outside-the-box challenge to make
a steel case frame by sheet metal processing.
We tackled the structuring of the frame by combining riveting and
welding under our development concept, "to make a high-speed,
compact, and light weight steel case frame with superior vibration
resistance characteristics."
Because there was a significant synergistic effect from combining
rivet structure and spot welding, we were able to manufacture a steel
case frame with two advantages, superior vibration resistance and
a flexible structure, thereby making it more robust.
This steel case frame was satisfying work, and achieved all our goals
including "cost reduction," "weight reduction,"
"lead time reduction," and "flexibility in design modification."
It required a continual process of a trial and error to complete,
but I believe that our accumulated efforts have made it possible for
us to release an excellent product which has market value. |
