1. 16. A Model System for Powder Injection Moulding – Physical Properties and Mould Filling Analysis

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

   Sammanfattning : 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. LÄS MER

3. 17. Influence of Microstructure on the Machinability of Prehardened Mould Steels

   Författare :Seyyed Mohammad Hamed Hoseiny; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prehardened mould steels; Milling; Drilling; Turning; Tool life; Machinability;

   Sammanfattning : Mould steels are mainly employed in moulding of plastic products, and also some metals withlow melting temperature such as magnesium alloys. The ever-growing usage of plastics in theindustry, especially the automotive industry, and in everyday life, has increased the utilizationof mould steels. LÄS MER

4. 18. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth

   Författare :Eva Frühwald; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; twist; shape stability; Norway spruce; mould susceptibility; larch; high-temperature drying; distortion; Technological sciences; Teknik; Material technology; Materiallära; Building construction; materialteknik; heat-treatment; Byggnadsteknik; KSTRWood;

   Sammanfattning : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. LÄS MER

5. 19. Preharvest Conditions Affecting Apple Quality, Antioxidant Responses and Susceptibility to the Infection by Grey mould (Botrytis cinerea)

   Författare :Tuyet Bui Thi Anh; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Malus x domestica; grey mould; preharvest weather; apples’ quality; antioxidants; harvest year;

   Sammanfattning : Apple fruits are rich in vitamin C and other antioxidants, which are beneficial for human health. During postharvest storage, there are losses as a result of diseases such as grey mould, caused by the fungus Botrytis cinerea. The present work has investigated how to obtain a high quality of apples, allowing long-term storage. LÄS MER
