Engraved 3D Brass Dies
Ofset Ltd. offers Production of Engraved Brass Dies:
Ofset Ltd can produce brass die / polymer counter die sets for the needs of printing houses. Also, the company offers the 3D relief service itself, which can be produced in the high technology factory.
To order a set of brass die / polymer counter die, the following specifications must be kept:
- Thickness of the brass die: max 7mm (standard), min 3mm.
- Max dimensions (X;Y) of the brass die: 350mm / 350mm
- Additional polymer counter dies can be produced by request
- The technology allows obtaining Hot Stamping and 3D relief processes at one time (simultaneously).
What exactly is an engraved 3D Brass Die?
Three-dimensional die is obtained through precise engraving of a brass piece by computer navigated engraving machine. Due to its specialized cutters, spinning with over 50 000 rpm, the engraving machine “carve”, with pre-defined software paths, a multilayer relief form on the brass piece. As a result, a negative relief is obtained. Consequently, a polymer counter die is produced, which fits ideally into the negative brass die.
The engraved set of die and counter die can then be installed on a Hot Stamping machine for the multi-layer embossing process.
Together with the exceptional quality of the relief, the brass die has another huge advantage – its productivity of more than 10 million hits with one single piece.
