Mattoon Precision Manufacturing Inc.
Mattoon, Illinois
Intern: Scott Nelson
University of Illinois, Urbana-Champaign
Mattoon Precision Manufacturing (MPMI) is a high precision machining plant
that produces brake rotors, lower control arms, damper forks, spindles, exhaust
flanges and other products for automotive industry. MPMI was founded in 1989
and currently employs 140 employees. The Mattoon facility has 83,000 square
feet of production space and 33,000 square feet of warehousing.
The intern project focused on opportunities to minimize waste and increase
energy efficiency.
Results:
The intern made the following recommendations:
- Establish a program to repair compressed air leaks. This project would
save over $1,200 annually.
- Recommended that the inlet air for the air
compressor come from the outside during the cooler months (October to April)
of the year. This project could save over $500 per year.
- Replace a trim
compressor with a smaller unit capable of efficient partial loading. This
project could save $9,600 a year, with a payback period of 2.9 years.
- Switch
four production lines from a semi-synthetic coolant to a cheaper, longer-lasting
full synthetic coolant. This project could save $2,400 a year, with a payback
period of seven months.
