Quality
Precision
Expertise
The highest quality and precision can be taken for granted in
the production of Unger thin ground doctor blades. It starts
with selecting high-quality raw materials and continues in the
production process. The blades are manufactured on state-ofthe-art
CNC controlled systems which ensure consistent quality
by a complex measuring process
Only high-purity, cold-rolled doctor blade steels with a proven
level of quality are used for Unger thin ground doctor blades.
A special, gentle grinding process (cooler grinding) ensures
consistent quality without altering the raw material.
After the grinding process, the doctor blade steel (lamella) is
gently polished using a new method. The finished doctor blade
is then rolled into environmentally friendly packages using a
fully automated process and entirely without the edges touching,
or it is cut to ready-to-use fixed lengths.
Unger thin ground doctor blades offer a consistently high
production quality, and the best material quality; this guarantees
high service lives and optimum results when used.
Unger thin ground doctor blades are characterised by exact
straightness and precise evenness.
Unger thin ground doctor blades have an exceptionally uniform
material structure without inhomogeneities and harmful
inclusions.
Unger thin ground doctor blades guarantee high wear resistance,
extreme tensile strength and hardness.

In the „ReadyCut“ design, Unger thin ground doctor blades
in different grades are cut precisely to the desired length and
supplied endless on a roll in a practical dispenser box with
easy to release tape connectors.
Unger thin ground doctor
blades in „ReadyCut“
design are available with
and without polished
section and in different
versions with
- straight edges

length can be used immediately and are ready for processing.
No extra work is required when changing over.
ReadyCut thin ground doctor blades create no waste and
facilitate easy and quick doctor blade change over without
