Notable Accomplishments

Re-designed the entire plant compressed air system to maximize compressor efficiency and eliminate the oil and water carryover into the production air lines which was a cause of larger than normal scrap totals. This redesign reduced production scrap by more than 20% and reduced energy costs 10%

Designed and installed a closed loop water recovery system for the extrusion process that saves an estimated 1.2 million of gallons of city water per month. A savings of over $4,000 a month on city water consumption.

Designed and built a device to dispense large spools of double-sided tape 24 inches in diameter by 22 inches wide, onto the extrusion as it is being pulled down the line. The device had to be operator friendly. Small enough to fit under the support rack, but strong enough to handle the weight of two rolls and being capable of allowing the line person to set it up without difficulty. Upon completion of the first unit, production requested three more identical units. These units helped to reduce scrap rates on four specific jobs by more than 80%.

Designed and implemented a Preventative Maintenance program that has consistently kept all production equipment at 99% or better reliability with 1% or less downtime

Designed a machine that reduces the time and effort required to perform the routine maintenance tasks of cleaning and de-burring conical twin screws. A job that once to took 4 to 6 hours could now be safely done in less than 1 hour. This machine was on display at 2000 NPE Show and Conference at McCormick Place

Authored and implemented all maintenance department work procedures and work instructions as required to achieve ISO 9001 certification.

Never failed any internal or UL audits
