  2. 1. Surface Interactions in Powder Injection Moulding

    Author : Elisabeth Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; powder injection moulding PIM ; rheology; steel powder; surface interactions; XPS; SIMS; adsorption; surface composition;

    Abstract : Powder Injection Moulding (PIM) is an attractive technique for producing complex components in large quantities my means of powder technology. The process includes mixing powder with a suitable binder, usually a thermoplastic polymer. Because of the large attractive forces between small particles the powder can be agglomerated in the binder. READ MORE

  5. 3. A Model System for Powder Injection Moulding – Physical Properties and Mould Filling Analysis

    Author : Henrik Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; processing conditions; thermal properties; computer simulations; rheology; powder injection moulding; mould filling; jetting;

    Abstract : ABSTRACTPowder injection moulding (PIM) is an important and accepted industrial technique for producing net-shaped components which combines the advantages of injection moulding and powder metallurgy. The properties of the feedstock, a mixture of powder and binder system (often based on a thermoplastic polymer), strongly influence the process. READ MORE

  6. 4. Surface Composition and Microstructure Control during Pressureless Forming and Sintering of Ferrous Powder Metallurgy Materials

    Author : Sílvia Magalhães; Chalmers tekniska högskola; []
