Obtaining of Biopolymer from Onion Used as a Binder in Powder Injection Molding Process

摘要

The very important strategy in parts processing by powder injection molding(PIM)technology is the use of organic polymeric materials made from raw and auxiliary materials and from renewable natural sources.Using natural polymers to obtain binders for PIM use is of particular interest.The inulin extraction from the onion bulbs has a major alternative in this area.
