How it's Made 

1

Slit

Metal is slit according to cap size. Check out the video below to see slitting. 

2

Punch

The slit metal is punched into "blanks." 

3

Thread

The blanks are then thread. If you ordered unlined caps, the process stops here & the caps are boxed pending final release.

4

Line

Keep reading if you ordered caps with an insertion or plastisol liner. Liquid plastisol is cured through our ovens (top) or lining material is punched and inserted (bottom).
