Abstract:
By controlling the process parameters and by using a polymeric production tooling having a plurality of mold cavities, different types of shaped abrasive particles selected from the group consisting of abrasive shards, dish-shaped abrasive particles, and shaped abrasive particles with an opening can be produced from the exact same mold. In one embodiment, the mold comprised a plurality of equilateral triangles and fractured precursor abrasive particles, dish-shaped precursor abrasive particles, or precursor shaped abrasive particles with an opening were produced from the same mold.
