Not only an aesthetic matter

Irizar Forge keeps the surface clean and free of defects permanently during all production processes: During forging, the surface is permanently cleaned by water pressure on the hot red piece to avoid surface scales flowing into the inside during the forming process.


Before heat treatment, the forging surface is cleaned by grinding one by one to eliminate any surface defect, indication, incrustation, marks, or scales, that could affect its mechanical and physical status and eventual results. Before DT and NDT, the forging surface is cleaned by shot blasting one by one to eliminate scale after heat treatment.

The hook is a critical item for several reasons, but above all because during its lifetime is subjected to fatigue, and this effect can cause small discontinuities in an area, turning it into a crack in a premature way and therefore, not only radically shortening the hook’s life, but risking sudden failure.
