Dynamic Manufacturing began its operation in 1951 as a family-owned and
operated retail transmission facility. Now, Dynamic remanufactures many
types of automatic and manual transmissions. Dynamic has ten facilities
in the Chicago area with over 750,000 square feet of warehouse, office,
and remanufacturing space.
Results:
Intern assignments included:
- Investigating aqueous cleaning as an alternative to organic solvent
parts cleaning to remove grease and dirt and metal fragment. Various cleaning
methods were tested that included immersion, immersion with agitation,
immersion with brushing, spray washing, and brushing with a flow-through
brush. Parameters
that were monitored included the concentration of solution, the
type
of solution, the temperature of the tank, and the residence time
in the bath.
A new continuous-feed ultrasonic cleaner was also investigated
that has the potential to save $200,000 annually.
- Determining the optimal operating parameters of the tunnel
washers that are used to wash the exterior of the transmission
housings. The tunnel washers
must use an indexing filter; the bath concentration must be
maintained between 2 and 5 %, and the pH between 9 and 11. The life of
the bath
can be extended
and water usage can be cut in half. The savings has not been
determined yet.
- Participating in an energy audit to collect and analyze data.
It was determined that by disconnecting some of the unnecessary
heating elements
on some of the machinery, the facility could save over $375,000
per year.
- Conducting a trial of a coolant filtration system on one CNC
machine to remove machine particles and tramp oil. The coolant
is run through a
filtration chamber to remove machined particles. The coalesced
oil is decanted off and the coolant can be fed back into the machine
for reuse. This will
save $5,600 per year in coolant costs.
