Flat Back Buttons - Third Pressing Operation
When a button is made with a flat back such as those used for medallions, the rim of the button is crimped at approximately a 45 degree angle. This leaves a flange extended inward and away from the flat back as shown in the lower left picture. The Third Press Operation allows the 45 degree flange to be pressed down onto the flat back so a more secure and flat crimp is obtained. This is shown in the lower right picture. The Third Press Operation is currently available for 1", 2", and 6" button sizes. Flat back buttons can be mounted directly onto plaques, trophies, and other applications with two-sided peel and stick foam disks.
How to Use the Third Press Operation:
• Assemble a button without a pin installed in the back.
• There is no room in the button assembler for pins during the Third Press Operation. Adhesive pins can be attached after the button is complete.
• Return the button face-up into the pick-up die cavity of the button assembly machine (where the shell, graphic and mylar were first placed when the button was made).
• Pull the press handle to the lower limit of its stroke to flatten the edges of your button. The third press will require more force than the previous strokes of the handle.
• Attach an adhesive pin to the button or use a peel & stick foam disk to mount the button on a trophy, plaque or medallion.
