What are the different types of engraving machines?

Heavy engraving machines can engrave metal sheets.

The different types of engraving machines depend on the surface used for engraving. Some stamping machines are of the heavy type, used for hard and rigid surfaces. Others are used for soft, flexible surfaces. Bookstores even sell hand-held engraving machines for quick and convenient uses.

The simplest stamping machine is the portable metal type, which works by pressing the two plates together to make a design. This type has only one image. Schools, government offices and organizations use this machine to engrave their seals on documents for authenticity. Industrial engraving machines are used for custom designs and can accommodate different types of paper and cardboard, with different sizes as well.

Portable metal machines are often used for stationary stamping.

A card engraving machine can also be operated manually. This is typically used for stamping polyvinyl chloride (PVC) cards such as IDs, credit cards and membership cards. The machine has an integrated alphabet and numerical wheel to spell out the words to be engraved. This type of machine is also compact and can be placed on a table.

Another type is leather stamping machines, specifically used for products made from leather. Companies use this machine to stamp their brands and logos on products such as bags, shoes and clothing. Decorative designs and holes can even be applied to the leather. Some stamping machines use thermal heating to make the leather soft, making it easier to stamp. Designs can also be customized on this machine.

For hard surfaces like steel and aluminum, a sheet metal stamping machine type is most useful. The machine also uses heat, along with pressure, to engrave images, allowing sheets of metal to pass through custom patterned metal rollers. This type of embossing is effective for aluminum foil used in floors, metal emblems and license plate numbers. Engraving companies often keep custom rolls for future use.

Embossing machines can be multifunctional. This becomes a very cost-conscious option, especially for small businesses. Multifunctional machines tend to be efficient at engraving softer surfaces such as paper, leather and PVC. Sheet metal still requires a specialized engraving machine.

Many, if not all, embossing machines also incorporate embossing dies to add color to embossed images. Cutters can also be integrated to automatically cut the surface to precise sizes. Many machines also have an anti-curl technology for smoother surfaces to ensure the embossed image is applied smoothly.
