The granular material obtained from walnuts is little hygroscopic, with little fermentation, and no bacterial flora develops.
They last long even in humid weather conditions;
People who work with this material do not need to wear any special protection equipment. No chemical treatment has been applied at our suppliers' facilities or during the manufacturing process.
Our products are 100% natural; no mineral products or other plant elements are added. We guarantee our products are 100% non-toxic and safe to use.
Our plant grains are obtained after dehydrating and degreasing walnut shells. Non-woody waste and any foreign mineral or metal elements are discarded. Aided by our vast technical experience, we obtain a 100% homogeneous product.
Fields of application:
Materials with different grain size are used to blast a wide range of surfaces, even if they are not chemically treated. They are used when the edges and shape as well as the surfaces of a part should not to be changed. They are recommended when no change on the surface is allowed.
Cleaning of gas turbine compressor blades.
Blasting of pistons and valves in turbines and pumps.
Aeronautical and automotive industries
Blasting of pistons, valves and cooling blades in turbines and pumps.
Fine grains are suitable for cleaning those delicate parts in electronic components.
Cleaning of moulds used to manufacture tyres.
Deburring of objects made of thermosetting materials
Satin finish of thermoplastic parts.
Cleaning of moulds.
Cleaning of electric motor housing before winding.
Paint stripping of metallic and glassy surfaces.
In foundry a grain size of 1/1.7 mm is used to make moulds and resin models.
Different grain sizes are used as well to create a honeycomb structure in the abrasive grinding wheels.
