highest quality
Engineered to the highest standard of quality                                                                           
To deliver the highest and most consistent standards of quality, Microblast fine ceramic beads undergo a fully controlled process as well as a stringent product quality inspection through advanced technologies such as particle size laser diffraction and morphological imagery. This enables ZirPro customers to achieve blasted components with perfect and stable surface finishes.
