The two companion insert molds for "H" Style Frames can be changed independently and individually.  A dummy insert is supplied for single insert mold production.  This results in exceptional versatility for tailoring schedules to virtually all inventory requirements including Just-In-Time delivery.

"H" Style Frames also offer special advantages for high volume production.  Two insert molds permit doubling quantities each molding cycle.  Also, there is virtually no need to interrupt production for maintenance or repair since inexpensive backup insert molds can be quickly installed.
