Design of hot extrusion molding device for the continuous production of pharmaceutical tablets
… make an impact in this sector, I focused on hot extrusion molding. Hot extrusion molding consists of heat melting a pharmaceutical resin in an extruder and packing it in a mold where it is allowed to solidify until it is ready to be ejected. I designed a hot extrusion molding system after …

Effects of processing on microstructure and properties of Ti-Ta Alloys
… from room temperature up to 750 [degree]C. Hot extrusion without further heat treatment was found to be insufficient to produce a homogenous, fully dense alloy. Elongation, an indicator of potential shape memory behavior, was shown to increase with increased martensite phase fraction, which …

Processing and Characterization of Light Metal Matrix Composites (LMMCS)
… reinforcement was fabricated via casting and hot-extrusion. This macro-composite was characterized in detail and conceptually developed through 3 stages. Initially, the Al volume fraction was not uniform in the macro-composite. In the first stage consequently (Concept 1, Chapters 4-6), …

Exploration of a new manufacturing process for improving mechanical properties in a hot extruded Al-Mg-Si alloy
… beams are typically manufactured by rolling or extrusion of billets, followed by artificial aging for strengthening. In conventional processing routes, billets are produced by casting prior to subsequent deformation. However, the cooling rates during casting and homogenization treatment …

Feature based costing of extruded parts
… the manufacturing cost of parts made by the extrusion process. Feature Based Costing (FBC) techniques have been used to develop the cost model, which is intended to be used early in the design phase of a part, when the geometry and the material are being defined in a Computer Aided Design …

Cryomilling and Spark Plasma Sintering of 2024 Aluminium Alloy
… be produced by Powder Metallurgy and finished by hot working. In this case, Powder Metallurgy is used to produce preforms with geometry closer to the final one than that attainable by other technologies, reducing production costs and raw material consumption. It is well known that nanostructure (D …
