Decoating

Decoating in coating centers & integrated coating process

Decoating / stripping is an important prerequisite for recoating with high level of quality. The old, used coating is removed so that the new one can adhere well to the reground tool and achieve a high degree of performance. Regrinding without decoating leads to a reduction in the tool’s lifespan.

In coating centers, the tools are usually decoated after regrinding

Decoating after regrinding can damage the final geometry of the tool and increase the risk of poor adhesion.

In addition, packaging, transport and repackaging pose a risk of damaging the tool.

By integrating the decoating process into the production of tools, decoating can take place before regrinding

Advantages:

Elimination of transport and packaging
Less damage caused by handling
Chemical destruction after regrinding is prevented
Edge pre-treatment is fully effective
Adhesion is optimized
The tool performs almost as well as a new one

Two types of decoating units

We offer two types of decoating units – for carbide & high-speed steel – which we are happy to customize according to your needs

CT20 fast decoating unit

CT decoating systems from PLATIT set new standards in decoating. The performance of this series is remarkable.

The new environmentally friendly wet chemical carbide decoating unit patented from PLATIT
Fastest decoating process worldwide
Decoating time is less than 3 minutes to the TiN adhesion layer; the decoating cycle stops automatically at the TiN adhesion layer
A single recipe for nitride coatings with TiN adhesion layer, independent of the tool size
Multiple coatings also decoatable
Shank tool holder for a wide range of diameters
Special holders available for hobs and inserts to avoid attacking uncoated areas
Max. tool dimensions [mm]: ø200 x 300
Cobalt leaching occurs only at the wear points
Common chemicals, available worldwide
The process takes place at the room temperature, neither heating nor cooling is required
The end of the process is detected by the built-in electronics, which greatly simplifies the operator’s daily work
