FABRICATION OF MOUDING FLASKS

Mouldmakingandcastingarecentral techniques inthehistoryofartanddesign.But theirusesand applications are longstanding and varied, andalso play a vast role in today's arenas of artistic production and industrial manufacture. Specific Project Objectives include: The student will understandtheprocess toproduceasheetmetalmouldingflaskandthestudentwillbeable toexplain how floor space andmoulding sandare saved throughmoulding flaskefficient design. The reason whyI select thismaterialsare, theyareavailablewithmeandalso theyeasily toget andalso the are very strong for doing this research work. The important properties which determine the utility of the material are physical, chemical and mechanical properties. The physical properties of metal include luster, color, size and shape, density, electric and thermal conductivity and melting point etc. The mechanical properties of materials are choose based on the ability to withstand forces and loads, While, the mechanical properties includes; strength, stiffness, elasticity, plasticity, ductility, bri tleness, creep and hardness. The moulding box has been successfully constructed using locally available materials which is less expensive compare with the one in the open market, The molding box was tested using a pa tern, A pa tern was inserted in the centre of drag and molding sand was added and rammed until the box was filled- The cope box was placed on top of drag box and molding sand was added and rammed until the box was filled, When the two box were separated and the pa tern removed, we observed that the alignment of two molds with respect to each other are correct, and this satisfied that the design moulding boxes was successful.
