Production Innovation

Mubea sets high internal standards to ensure a high level of quality and economic efficiency by means of innovative and extremely rigorous production methods, starting with the production of the raw material.

A majority of the strip material used is produced to very tight tolerances. Depending on the disc thickness, the disc blanks are manufactured by punching (Group 1), fine blanking (Group 2) or plasma arc/flame cutting (Group 3). Disc springs of greater material thickness are machined all over to remove surface imperfections. Depending on the requirement, disc springs can be heat-treated martensitically or bainitically to extremely tight hardness tolerances. Subsequent shot-peening will improve the fatigue life of the springs. Our standard corrosion protection, phosphating and oiling, is performed in our own facility.

Complete monitoring of the various production stages guarantees the high quality of Mubea disc springs.
