The concept of including hardened and hard chrome-plated piston rods in the product portfolio has paid off. The demand for piston rods has increased significantly and the manufacturing processes have been further optimised.

In-house induction hardening allows variable surface hardening and hardening depths. The well-functioning network with steel suppliers and hard chrome plating companies ensures flawless quality results and short production times.

BüMi is therefore in a position to fulfil almost all requirements in terms of

• Materials (must be induction hardenable)
• Dimensions (including intermediate dimensions)
• tolerances (freely selectable up to IT5)

to fulfil.

The wide range of machining options naturally also allows the complete production of piston rods, which can be supplied in quantities and as required for blanket orders.
