Effect of Temperature, Holding Time, and Addition of Sn on Density on Metal Injection Molding Sintering Process

Metal injection molding (MIM) is a metal forming technique that combines powder metallurgy with plastic molding. MIM very efficient in manufacturing small and complex products large quantities. The process has four steps: mixing, debinding, molding, sintering. This research was conducted to determine the effect of variations Sn addition, temperature, holding time on density Al-PP after sintering process. Density mass per volume so find out products, use 3D scanner attempted along EinScan application mesh mixer. Taguchi method used for data processing influence density. calculation percentage contribution showed affected by 47%, 21%, 3%. Also, 2% addition yielded reasonably good microstructure formation compared without 1% where many voids remained specimen (the more significant voids, lower density).
