Pad Printing for Metal Fabrication
Pad printing is commonly used in metal fabrication during the final design period. It is the process of transferring a 2-D image onto a 3-D part. Pad printing is highly intricate and precise. An etched plate and pad are used to transfer the image. Pad machines vary depending on the colors and size of the 2-D image.
When is Pad Printing Used for Metal Fabrication?
Pad printing is most often used for promotional or branding products. For example, an automobile company may want to add their logo to a custom sign. Other popular pad printing applications include pens, flash drives, and silicone items.
How Does Pad Printing Work?
Pad printing utilizes three main components: the plate, ink cup, and pad. The image is etched into the plate. Then the ink slides over the etched plate. Finally, the plate is placed on the pad where it is etched into the metal, creating a 3-D part.
The Parts
- The pads are made of silicone material. They vary in shape and size depending on the image. Common pads are round and rectangular.
- The ink cups are typically made of a ring and the cup. The ring is used to ensure ink is only left on the etched potion of the cup. Rings are made in ceramic, metal, or plastic depending on the manufacturer.
- The plate holds the image to be printed by etching the 2-D image into the plate.
