Aluquench is one of our proprietary technologies. Quenching in a polymer bath optimises the machining of workpieces with various wall thicknesses in particular. With conventional quenching in water baths, thin-walled areas cool down significantly faster than thick-walled parts, which has an adverse effect on the residual stress in the component.
However, in Aluquench, the polymer is deposited on the thin-walled, already cooled areas of the component, preventing further rapid cooling. The polymer cannot settle on the thick-walled areas, which are still hot. As a result, the cooling process continues until these areas have reached the required target temperature.
