3. Tribological aspects of aluminium extrusion dies
Abstract : Extrusion is a common method to manufacture long products of aluminium, such as beams, rods and tubes. The aim of this thesis was to improve the material in the die bearing surface, and thereby the service life of extrusion dies through wear studies of actual dies, and experimental simulations.

4. Modeling of the Stainless Steel Tube Extrusion Process
Abstract : Seamless tubes of stainless steel can be extruded using glass as a lubricant in the Ugine-Sejournet process. The process is performed at high temperature and is associated with large deformations and high strain rates. READ MORE

5. Wheat Gluten -Based Materials and Composites: Extrusion, Casting and Antimicrobial Properties
Abstract : The use of bio-based polymers as packaging materials has gained much attention due to increasing environmental concerns regarding non-biodegradable petroleum-derived plastics. Wheat gluten (WG) is a valuable renewable resource for the production of bio-based materials because of its low price, biodegradability, good film-forming properties and good gas barrier properties under dry conditions.
