- Focus on 1 part flow
- The Boeing company is committed to the idea of one part flow and
- Fewer mistakes
- More cost effective
- More productive
- The current system uses carts that hold 4 mandrels per cart. Our
proposed system will employ smaller carts that will hold 1 mandrel each.
- This will allow the curing process to begin directly after each
duct has been fabricated.
- Smaller carts will be easier for employees to handle, and will be
- Decrease mandrel handling time
- Eliminate the need for large overhead cranes
- Cranes are slow, cumbersome, and dangerous.
- Nylon straps are currently used to lift the mandrels. This
practice poses numerous safety hazards.
- Operating overhead cranes safely requires two people.
- Increase the safety of handling mandrels
- The transport unit must withstand temperatures of 300°F, which is the
curing temperature of the composite materials.
- Ten transport units must fit in the curing oven at one time.
- The system must handle all sizes of mandrels.
- 3" to 14" diameter
- 13' to 14' long
- Up to 1000 pounds
- System should incorporate all stages of duct production.
- Duct Extraction (removing cured duct from the mandrel)
