Döktaş Manisa performed a project to reduce the part weight of an extension bracket. The goal was to convert the material and the process from a cast iron sand casting to an aluminum low pressure die casting including a T6 heat treatment, while guaranteeing the required specification and mechanical properties.

The bracket used in heavy duty trucks had been manufactured as a ductile iron sand casting. Döktaş was approached by the OEM to evaluate the feasibility of realizing the part in aluminum while maintaining the specifications defined by the customer. After a preliminary analysis and discussions regarding feasibility, an AC 43300 aluminum alloy was selected as the material, and low pressure die casting including a T6 heat treatment was defined as the preferred process.
