Innovative Foundry Technologies for Safety Aluminum Suspension Parts and Complex Castings

Low pressure die casting technology (LPDC) has been proven to satisfy the quality standard requirements of safety aluminum suspension parts. The process gives freedom to innovative and lighter design, like tubular hollow sections, through the use of cores. With the goal of having higher quality coupled with competitive production costs, an innovative process has been investigated. The GMBOND™ core making process with a water based bio-polymer binder has been used in the LPDC of heat treatable T5 alloys specifically developed to get the required final component performances. One of the goals of this activity has been to make a comparison between the cold box technology and the GMBOND™.
