Quoins


“High Speed” Lockup Quoins If you’re looking for a fast and simple way to lock your die in the press or chase, look no further. Bar-Plate is now the only US manufacturer of “High Speed” Quoins. Our unique construction applies even pressure across the entire face of the quoin, ensuring a tight fit. Our positive locking feature prevents slippage. The one-piece construction, along with a simple turning motion of the quoin key, provides unparalleled speed for tool lock-up, and special plating prevents corrosion. Each quoin is inspected throughout the manufacturing, assembly, welding and plating process, and each quoin is stamped with a warranty date prior to shipment.

BP Torque Quoin Keys

Torque Quoin Key

Bar-Plate’s new Torque Quoin Key reduces the chance of breaking the quoin. The most common reason for failure of a quoin is over tightening. Too much force is applied to tighten the key either by hand, hammer or tool extension. Our new Torque Quoin Key allows 105 inch pounds of torque, which is more than sufficient to hold the die in place even on Bobst presses. In fact, Bobst recommends 80 inch pounds. Bar-Plate’s new Torque Quoin Key can be used to loosen the quoin simply by sliding the barrel down over the retention nut. Slide it back up and your ready to tighten the quoin.
