Microblasting

Microblasting with the PEENMATIC® und MICROPEEN® Microblasting equipment for perfect Surfaces

iepco microblasting technology can be used for eroded surfaces as well as for ground and HSC milled cavities and molded parts. While steps, slate formation or tears in the base material can occur during milling, furrowing, grinding burn or grinding wheel residues are undesirable side effects during grinding. These sometimes unpleasant processing phenomena can be easily and simply removed with iepco microblasting.

Weisse Zone auf erodierter Oberfläche
Starting position: Eroded surface

In both wire and die-sinking erosion, a so-called white zone or melting zone is created during spark erosion. This enamel layer can have a negative impact on all coating processes in terms of layer adhesion, coverage and cracking. It can neither be etched (structure etching), nitrided (gas and bath nitriding) nor coated (galvanic, PVD and CVD).

CONCLUSION: The white zone or melt zone must be removed from the mold surface.

Entfernen der weissen Zone von erodierten Oberflächen
Step 1: Cleaning

If the surface quality allows, we recommend blasting the parts after eroding with a fine, abrasive IEPCONORM blasting grain with little pressure down to the diffusion layer of the base material.
With the micro blasting systems from iepco you can optimally remove the white zone or melting zone within a few minutes without weakening the edges and corners. Dimensional and shape tolerances are retained.

Step 2: Shot-Peening

After removing the white zone, compact the diffusion layer with a round blasting agent under slightly increased pressure. This step ensures that the alloy components of the material are better fixed in the base material.
