Brake discs are a key component and major safety factor in any vehicle’s braking system. They are often made of a special grey cast iron and must withstand high thermodynamic loads. Leading brake system manufacturers such as Brembo opt for HA’s Cold-Box binder systems when casting brake discs. 

The challenges of casting grey cast iron brake discs

Cores for brake discs are among the cores with the shortest manufacturing cycles. This means that foundries need a particularly reactive Cold-Box binder with the shortest possible gassing and flushing time. For example: with a one second gain per cycle, a foundry can produce 100,000 more brake disc cores per year.

High performance and improved environmental compatibility

As a “turbo binder”, many foundries use an aliphatic Cold-Box binder system, which replaces aromatic solvents with fatty acid esters from renewable raw materials. Binders from HA’s FR line actively contribute to the reduction of formaldehyde emissions in the foundry process. Additives of the Feranex series – also produced from renewable raw materials – help to prevent veining and at the same time ensure high dimensional stability.
