Product Description

Leaf spring for DAEWOO

Automotive leaf springs are also called blade springs.

The potential effect of heating and curing of electrophoretic coating film on residual stress and fatigue life after leaf spring shot peening The heating and curing temperature of electrophoretic coating film is 160~170°C and the time is 30min. This process may have a negative effect on the residual stress after leaf spring shot peening, thereby shortening the fatigue life and actual service life of the leaf spring. On the production line, 8 pieces of leaf springs after shot peening were randomly selected, of which 4 pieces were only shot peened without painting, and the other 4 pieces were electrophoresised, baked and cured (temperature was 190°C, time was 30min), and then the residual stress was measured with X350 stress detector.
