Costs Models in Design and Manufacturing of Sand Casting Products
In the early phases of the product life cycle, the costs controls became a major decision tool in the competitiveness of the companies due to the world competition. After defining the problems related to this control difficulties, we will present an approach using a concept of cost entity related to the design and realization activities of the product. We will try to apply this approach to the ...
متن کاملIntegration of CAD and rapid manufacturing for sand casting optimisation
In order to reduce the time and the costs of the products development in the sand casting process, the SMC Colombier Fontaine company has carried out a study based on a tooling manufacturing with a new rapid prototyping process. This evolution allowed the adequacy of the geometry used for the simulation to the tooling employed physically in the production. This allowed a reduction of the wall t...
متن کاملAdditive Manufacturing of Casting Tools Using Powder- Binder-Jetting Technology
This chapter presents the use of the additive manufacturing (AM) method powderbinder-jetting (PBJ) for the generation of molds and cores for casting applications. Theoretical information on process steps and the binding of particles is given. For the based chemistry, examples are presented and the transfer from conventional produc‐ tion processes to powder-binder-jetting is explained. For sand ...
متن کاملStudy on Pyrolysis of Carbonaceous Additives in Green Sand Foundries
This research evaluated the hydrocarbon emission characteristics during pyrolysis of four carbonaceous additives that can be used in green sand foundries. These included a highly volatile bituminous coal, anthracite, lignite and cellulose. The samples were flash pyrolyzed in a Curie-point pyrolyzer at 920 C with a heating rate of about 3000 C/sec. This simulated the fast heating conditions that...
متن کاملApplication of Additive Manufacturing in Marine Industry
The advantage of additive manufacturing (AM) (e.g. reasonable time and expense in prototyping, and reliable product) has triggered the idea of using this method in manufacturing of marine vessels components. The current article tries to introduce basic concepts of AM method and its application in marine industry; have a glance at additive-manufactured parts microstructure; elaborate the challen...
