Big variety: Challenges in closure quality inspection
It’s not that easy, but it’s safe to say that all kinds of closures need attention in quality inspection as there are numerous defects that can occur during production. While quality inspection is a necessity for standard one piece closures, it’s especially true for sports caps which have gained popularity in recent years. The diversity and complexity of these plastic closures have rapidly evolved to support a wide variety of functions. Due to this, these more complicated closures demand high quality in order to perform their essential duties.
