Clamps that need no bolts
Powered clamps on a press hold each mold by a standard mounting plate, so no bolts are turned at a change.
| Cost | About $20,000 per press |
| Payback | About fifteen years |
| Limitation | It removes only the bolting: we count fifteen minutes on each of about 140 changes per year on one busy press. Every mold that runs in the press needs the same mounting plate. |
