Psolid innovates plastics processing
The high optical clarity needed on products, especially for plastic injection moulding, requires using highly polished surfaces. Brush finishes are needed for plastics processing as well. It is a very time-consuming process with high costs to produce high gloss polished or brushed finished surfaces, so cost savings are absolutely essential.
The future-like diffusion coating Psolid provides a homogenised micro structure that is highly resistant to wear, corrosion and scratches. Additionally it improves the polishing properties and shortens the polishing time significantly. Time savings of up to 50 % can be achieved thereby for transferring a brush finish into a high gloss polished surface.

Low surface energies optimize flow, minimize deposit adhesion and thus make mold cleaning significantly easier. The resistance to flaking and embrittlement of the coating avoids any visible surface defects in the produced plastic tools.
A special feature of Psolid is the fact that the internal functional surfaces of through and blind holes are treated successfully. This makes the treatment particularly useful for multiple-cavity tools.

Reworking of conventional coated surfaces require de-coating, refurbishing and applying a new coating. The fact is that this costs money and causes production down-time. Reworking of Psolid coatings is extremely uncomplicated and can be done on location. The coated surface is still weldable using the TIG method or laser.

Use of Psolid for corrosion resistant steels or cold working steels with high chromium content provides increased hardness without loss of corrosion protection –opposite the normal effect from standard coated surfaces: Psolid forms a passive layer on the surface of the tools and moulds providing a high resistance to wear and pitting. A high surface hardness up to 1.600 HV can be achieved especially for coated hot and cold working steels. Despite of a diffusion depth of 10-50 µm the coated parts stay deformation and distortion-free. Furthermore by applying a combination treatment a PVD coating can be added to the surface improving the tools durability even more.
Also the coating of large tools can be provided at Sulzer Metaplas - maximum tool sizes of 1.000 to 1.600 mm can be coated at the service locations.

Not only the plastic processing industry but especially polishing shops and tool manufacturers benefit from the significant advantages of a Psolid coating.
Time savings – thanks to the coating – enormously reduce production and maintenance costs and improve the “uptime” of the tools as well.
