Item Experimental investigation of sheet metal forming using a recyclable low melting point alloy tool(Walter de Gruyter, 2016-05) Ünver, Ertu; Jagger, Brian; Doruk, Emre; Fındık, Fehim; Durgun, İsmail; Sakin, Ali; Kuş, Abdil; Uludağ Üniversitesi/Teknik Bilimler Meslek Yüksekokulu/Makine ve Metal Teknolojileri Bölümü.; AAG-9412-2021; 57196667786Due to intense competition in automotive industry, new car models have to be launched as quickly as possible. A re-evaluation of the design and development phases has reshaped product development in order to get product earlier than competitors. Prototype production is one of the longest stages of product development due to physical verification activities. Shortening of this process will provide more opportunity to get project schedule earlier. Rapid prototype technologies are usually used as a guide for visual and packaging analysis. However, there is a requirement to use these parts for functional testing as well. Developing alternative rapid tooling methods which shorten the physical prototype production phase, while adequately supporting visual, packaging and functional aspects of sheet metal forming, can lead to considerable savings in vehicle prototype development. In this study, sheet metal prototype part using recyclable low melting point alloy was experimentally investigated by analysing dimensional conformance of tools and parts. In addition to wear performance, thickness reduction was investigated for stamped parts.Item A study of injection moulding with bismuth alloy(CRC Press, 2013) Ünver, Ertu; Jagger, Brian; Durgun, İsmail; Bartolo, H. M.; Bartolo, P. J. D.; Alves, N. M. F.; Mateus, A. J.; Almeida, H. A.; Lemos, A. C. S.; Craveiro, F.; Ramos, C.; Reis, I.; Durao, L.; Ferreira, T.; Duarte, J. P.; Roseta, F.; Costa, E. C. E.; Quaresma, F.; Neves, J. P.; Kuş, Abdil; Uludağ Üniversitesi/Mühendislik Fakültesi/Otomotiv Mühendisliği Bölümü.; AAG-9412-2021; 57196667786There is a demand to produce parts in small quantities, using cost effective injection moulding processes. The emerging economic case suggests there will be advantages in producing injection moulding tools for short duration low volume production runs where the tool is rebuilt for each manufacturing cycle. CAD/CAM, Rapid Prototyping (RP) and digital technologies help to bring new products to market faster. Mould inserts are traditionally produced using expensive and time consuming CNC machining processes. This article presents development of an injection moulding tool where rapid tooling, bismuth-tin mould insert and injection moulding are used to manufacture one hundred plastic parts. It describes the manufacturing methods applied and the use of manual and 3D scanning methods. It also evaluates the surface finishes and dimensions of the parts produced in the tool.
