There are ample opportunities for issues to arise when a closure is applied to the finish of a glass container.  Problems such as high torque removal, leakage, rusting, cork extraction issues, excessive finish coatings and chipped finishes have been the focus of numerous investigations by American Glass Research.  Our exposure to all of these issues provides a wealth of background that can be brought to bear on your behalf when issues arise for your company.

 

We are fully equipped to quantitatively analyze closure problems with an array of equipment that includes an optical comparator for dimensional measurements, torque testers, the AGR Finish Coating Measurement System (FCMS), and an Instron tester capable of replicating a cork extraction.  In addition, our background in glass manufacture and fracture analysis allows for easy identification of visual problems such as mis-formed finishes (line-overs, overpresses, and saddle finishes).
