Polar Pin

Glossary of Terms

Hard Enamel

Referred to as "Cloisonne", It is a die-struck process with the use of special colors containing a glass like mixture. Colors are fired one at a time at 1,700 F for two to four minutes

The finished item is hard baked using an open flame and buffed to give it the smooth hardened finish.This produces a jewelry quality pin with a high level of detail and color.

Epola Enamel

Similar to "Hard-Enamel", a refined look at a lower price.

Pantone Matching System ( PMS) can be used when colors need to be exact.

Thickness of the metal is the same as hard enamel.

Offset Printed

For complex color and color gradation, the design is usually created using offset printing process.

This process allows high quality reproduction of logos.

The design is protected with a clear epoxy dome.

Screen Print

This process is ideal for multi-colored designs. Color-matching is available while providing the fine detail and close color on color registration.

The design is protected with a clear epoxy dome.

Photo Etched

An image of your design is transferred from a photographic negative onto the surface of the metal. Same principle as pictures taken by camera. Your design is then etched into the brass using an acid-reaction process. All the acids and other impurities are carefully rinsed off. The indentations are then filled with the enamel colors. Colors are inserted by hand, one at a time, using different sized syringes. The sheet of metal is then fired at 450∞F for 12 to 15 minutes. Pins are then cut out of the sheet according to your custom design. Non-colored (raised) sections of the pin are then plated to a shiny gold finish. An optional epoxy protective coating (dome) can then be applied to protect the color enamels from fading or cracking over time.

Compared to pins of cloisonne and die struck soft enamel, the advantage to photo etched pins are that process is less expensive and lighter in weight.

PVC

Rubberized PVC Items are custom molded and made of PVC. Key Tags, Luggage Tags, Coasters, Lapel Pins, Zipper Pulls and Magnets

Multiple levels can be obtained using a 2-D mold, or a 3-D mold can be created for a 3 dimensional look.

Casting

An alternative to die-struck the cast processes begins with a cavity formed from steel ( a two-sided die ) where a melted metal is injected to create the item.

Once hardened, the die is opened, allowing the item to be removed for and plating.

Die Struck

The process begins with your design being struck in to a soft piece of brass or steel that is then hardened.

Then this "die" is used to strike the softer metal, to transfer your design to the material, which is then hand finished.
