Multi-Component High Pressure Die Casting (M-HPDC): Temperature Influence on the Bond Strength of Metal-Plastic-Hybrids Manufactured by M-HPDC

M-HPDC is an In-Mold manufacturing process combining high pressure die casting (HPDC) and Injection Molding (IM) within a single die. The M-HPDC cycle starts with the injection of molten aluminum via a conventional cold-chamber HPDC process and is followed by an IM process into the same die in order to manufacture a metal-plastic hybrid specimen. The new Hybrid-III die is equipped with extensive means for temperature control, e.g. multiple cooling circuits, heating cartridges and thermocouples in order to adjust the temperature in the joining area. It is imperative to gain knowledge about the actual temperature close to the joining area and its influence on the hybrid specimen. The overarching goal of the investigations is to derive design guidelines for the M-HPDC process in order to expand its applicability to complex geometries. Extensive test series are currently carried out for this purpose. The first results of these investigations will be presented.
