SUCCESS STORY
 
Chase Instruments Corp. 
 
COMPANY/LOCATION: Chase Instruments Corp., Rockwood, Tennessee 
PRODUCT: Medical devices from glass 
YEARS IN BUSINESS: 10 years in Roane County 
EMPLOYEES: 290 
 
SITUATION:  Among the products that Chase Instruments produces is a glass vial with a screw thread that is unique to the glass industry. Chase had encountered a problem measuring the minor diameter of the screw threadthat is the diameter of the finish without the thread projection. The company wanted a way to precisely measure this diameter in order to meet quality control standards. 
 
PROJECT:  The company contacted the Oak Ridge Centers for Manufacturing Technology after a consultation with the University of Tennessee Center for Industrial Services. Working with Chase on a solution to their needs, ORCMT researchers determined that a private company existed that could produce the measuring device that Chase needed to solve its problem. Because they cannot compete with private industry, ORCMT suggested that Chase have the device designed and built by the private company. However, Chase asked the Metrology Center at ORCMT to test the accuracy of the measuring device to be sure it could meet the necessary accuracy standards. 
 
RESULTS:       The Metrology Center tested the device to make sure it was giving accurate measurements and the company is now using the device in production. The device has improved the company's quality control process by giving them a way to ensure that the screw threads are within specifications. 

"It has reduced our scrap and increased our productivity. Before we had a 
go-no-go gauge for the screw threads. Now we can measure to be sure if the production is within specifications," said Steve Jolly, director of quality assurance for Chase.
