Casting/ materials in T Rex Fabrication (Arms and Ribs)
It is very important to consider the process and material used in the tasks performed in terms allocation of resources. One manufacturing processes used in fabricating the T Rex is casting. Casting is a manufacturing process in which an object is made by pouring a liquid material into a hollow or cavity mold until the material cools into a sought solidified shape. The casting method used specifically was the one piece mold casting which was used to fabricate the arm and ribs patterns. The one piece casting method is when you cast an object that has flat back side. Therefore, it was the preferred casting method because the 3-D pattern was flat from the back side which gives the operator a specific side to pour from. The advantages of the one pierce mold casting include simplicity, low cost, and no seam lines in finished patterns. As with all manufacturing methods there some disadvantages to casting that include it can only be used with non-ferrous metals that has low melting temperature and long cooling time. As for the material used which consisted of a silicone mold making rubber and a special chemical composition (catalyst) with a usage ratio of 10 to 1. The calculate amount used for the silicone rubber was 918 g and 92 g for the catalyst. The silicone mold making rubber was used because it has unique advantages that include easy use, quick setting, does not need vacuuming and especially applicable to one and two piece molds. The main disadvantage is that it takes long time to cure. Another major factor in choosing the appropriate materials is sustainability. One method of recycling silicone rubber is to depolymerise to recover the silicone monomers, and then you can recycle each material. This way all the materials can be recycled and the product becomes sustainable. http://www.toolingu.com/definition-200140-18223-casting.html http://www.harmonyrecycling.com/silicone_rubber_recycling.html
