Moulding a Shape

Integrative Studio Week 10

After discussing our mind map a with the faculty our next step was to create mind map be. So we had to pick a category out of our first mind map related to the discipline we wanted to choose, and build upon this category to create a second mind map. The topic that I was interested in was any manufacturing process, and in particular costing and molding. So I discussed this with the faculty and we came to the decision that I could choose Molding as my topic for mind map B.

Moulding itself is divided into several parts. Moulding can be used to create new forms, form seals or barriers, and depends heavily on the durability and flexibility of the role material used. Anything can be moulded around us but the most common materials used in moulding include concrete, latex, silicone, plastics, rubber, and metals.

Since the category was so fast I was asked to narrow it down to yet another smaller subcategory, and I chose injection molding. The rest of this class was spent by me researching about injection moulding, the components it includes, the structure of the mould, the types of injection moulding, and the applications of it.

The injection molding process is divided into several parts. First plastic granules/pellets are frayed into a funnel called the hopper. Next these granules are melted and fed into a reciprocating screw which creates an evenly melted viscous mixture. This mixture gathers at the front of the screw and into the nozzle. The nozzle then injects this into the mould which is rapidly cooled by cooling lines surrounding the mould. Lastly, the cold part is ejected from the machine and thus we have a plastic moulded part.

After understanding the basics of the process I created a category for it. Another category was based specifically for the design of the mold. The next category was for the material used for the mold. Another one was for the applications of injection moulding, and this was the most expensive category since injection moulding has several applications. Another very interesting category was the mistakes that commonly occur in injection molding.

After the first mind maps I had realized that a mind map is not something that should resemble a flow chart. A mind map is supposed to be interactive, and should have icons and elements that help the viewer understand the hierarchy, and drives their attention towards topics and sub topics. I implemented this into this second map and there is a vast difference in what my first and second mind maps look like. I also understood how to represent data that I had read on paper or online in a visual way and comprehensible way.
