Manufacturing of Aluminum Alloy Parts from Recycled Feedstock by PIG Die-Casting and Hot Stamping

PIG (Pin-Injection-Gate) die-casting and hot stamping was developed for fabrication of small-sized thin-walled aluminum alloy parts from the recycled feedstock. The pure granules were utilized as a feedstock model materials. measured mass with estimated weight 3D-CAD (Computer Aided Design) products poured into PIG-nozzles before injection. After quickly melting by induction heating inside PIG-nozzle units, melts injected die cavity through PIG-nozzle. No furnaces no crucibles needed to store melt stock in different conventional system. clamping mechanism huge loading machine also significantly reduce energy consumption casting. Much less wastes yielded these processes; ratio product waste, or, materials efficiency nearly 100%. Nitrogen supersaturation TiAlN coating used protect surfaces severe adhesion melt. gears mobile phone case fabricated this process. X-ray tomography proved that both had cavities, pores shrinkages their inside. Using unit, micro-pillared heatsink investigate holding temperature effect on aspect micro-pillar height width.
