Title: Development of a Preventive Maintenance Program for Tooling Used in Powder Slush Molding

Abstract

ORNL collaborated with Faurecia Interior Systems to investigate the feasibility of developing a thermomagnetic preventive maintenance program for nickel tooling used in powder slush molding. It was found that thermal treatments at temperatures greater than 500°C can anneal strain hardening in nickel tooling and a range of temperatures and times for effective thermal annealing were identified. It was also observed that magnetic fields applied during thermal annealing do not alter the kinetics of strain hardening annealing. The results obtained in this investigation provide a foundation for establishing a preventive maintenance program for nickel tooling.

  • Since 1979, the Institutional Conservation Program's main emphasis has been on funding capital improvements to increase the energy efficiency of schools and hospitals. Improved building operation and maintenance techniques as a means to reduce energy consumption have been encouraged, but despite evidence showing greatly increased energy savings from such efforts, relatively little has been accomplished in this area. To meet this deficiency, the Wisconsin Preventive Maintenance, Repair and Operational Services (PROS) Pilot Program was designed to increase and maintain the energy efficiency of schools by emphasizing building operation and maintenance techniques within the context of an overall facility management program.more » The PROS final report provides complete documentation of the project's history, operations, methods, and results for those who might want to replicate the program. Drawing upon Wisconsin's experience, this report will also indicate areas in which the program might be improved.« less
  • The Initial Report and the First Interim Progress Report included a copy of the Preventive Maintenance Questionnaire. In the past two years, the rating went from 80 (excellent) to 82 (excellent). Progress is still being made in most areas but it consists of fine tuning the existing programs. The Generation Statistics are included. The availability factor for the past 12 months was 79.3% for Unit No. 1 and 93.9% for Unit No. 2, an improvement of 5.3% and 5.9%, respectively, over 1980.
  • Progress is reported on the following objectives to: perform a benefit/cost evaluation of a preventive maintenance program designed to enhance the availability of a central station power plant and document the program at a level of detail which will assist other utilities in making a decision as to whether or not to implement a preventive maintenance program.
  • Result of the CUEA Preventive Maintenance Program is that the number of corrective work orders at Hayden Station is decreasing while the amount of preventive maintenance work is increasing. Other results are: the need to perform work on a highest-priority basis has been reduced by 19%; overtime work, previously 11%, has been as low as 1/2%; the maintenance backlog has been reduced by 15%; maintenance costs are down by 26%; and direct maintenance work productivity has increased 6.2%. Equivalent availability (power generating capability) has improved 22% on generating Unit 1 and 11% on generating Unit 2; and forced outage ratesmore » are down 6.8% on generating Unit No. 1 and 2.3% on generating Unit No. 2. Although the final net cost benefit will not be known until after several years of operation, it is now estimated that the net benefit at the Hayden Station will be in excess of $1.0 million per year.« less
