The artwork will be imported into the engraving machine program to edit for mold engraving.
In the engraving process, we need to pay attention to the thickness of the knife pattern. After engraving, checking whether there is any mistake or not. The mold is going to through heat-treated in order to enhance the hardness and durability of the mold.
Process 3: Suppression
The mold that has been heat-treated continue to the next procedure–die struck. The metal material will present before the design artwork.

Soft Enamel Pins VS Hard Enamel Pins
Although, soft enamel pins and soft enamel pins have a similar production process, there are still some differences between them, there are some details for helping you to choose lapel pins style.
The materials are usually copper, iron and zinc alloy, the copper is the most common and also the most expensive. Comparatively speaking, The iron is cheaper. The surface of soft enamel pins has obvious layered effect and good texture, so soft enamel pins belong to high-grade level and are widely used for advertising, brand promotion and membership recognition.
