“How It’s Made” Reflection

Episode Date: Season 12/ Episode 6

Product Presented:

1. Carbon Fibre car parts like bumpers and spoilers are nearly as strong as steel ones, yet only 1/5th the weight; 2. Hand Dryers, used in many public washrooms and saves paper (trees); 3. Recycled Polyester Yarn are made from recycled bottles and turned into clothings.

Explain Three + Manufacturing Steps For Each Featured Items

Features 1: Carbon Fibre are made of fibre that’s tightly woven with fine threads made of virtually pure carbon, to create  this first they need to use paste wax and brush into a carbon fibre mould, then they spray non stick coating on it. Then they lay out the carbon fibre material seven times on the mould, glued by dissolving glue and apply a permiable material called flow media. Lastly they place a plastic bag over and put reson, which saturates 2 layers of carbon fibre to laminate them into shape of car part of be molded into almost anything. 

Feature 2: The first step in making a hand dryer is to make a circuit board with a micro processor, which controls everything, it’s then run through a chemical cleaning process and placed in a machine, which fuses the components. Then they make a motor and connect them, after a electrical heating elements is connected to the circuit board. Lastly the outer shell is made by cast from zinc, then polished and placed in different substance, lastly all the parts are combined.  

Feature 3: First step to manufacture recycled polyester yarn is by converting bottles into chip forms, then pulse a hot air tosses it to make the shells hard and is moved by worm screws threw heated screw into heated recycled polyster. Second manufacturing step is changing polyester into yarn, with a press dye plate, then moved to opening where 68 holes press shape of polyster into filaments. It’s laslty air buffled together and pulled into heat rubber rollers, which stretch and re-a lines molecules, it is pulled by automatic spoiler making it ready to be made into clothing.

Articulate the relationship between designing objects and designing the manufacturing processes used to make them?

An object usually starts with a design of a product, but can’t be completed wihtout being manufactured. When designing an object, designers need to think of the problems, which may occur during the manufacturing process, like problems with the machinary needed, materials and others. Manufacture dsigners need to design on how to manufacture an object the easiest and cheapist way possible, with having problems. If them some problem in the maufacturing that doesn’t work out they need to go back to the original design to change something to make it work in the processing. The connection between the two is important, for example the carbon fibre material both design and manufacture process need to prepare themselves on how it’s going to be made, what is needed and others, inorder for the design to be created in the shortest, easiest and be the design that is needed.

Demonstarte an understanding of the following technologies in relation to product design

1. Tool + Die Making: In designing, preparing on what tools and die making items are important, the designer needs to know what tools are needed inorder to make the item. For example for the hand dryer, what tools are needed to make the circuit board? What tools are necessary?

2. Mould Making: Is usually a manufacturing where liquid or other material are paused into moulds, when desiging a product, the designer needs to know how to create an item, mould making are one of the easiest ways of making complex shapes and materials for example the designer used moulds to create the carbon fibre parts because it’s the easiest way to make it.

3. Pneumatic + Hydraulics: Are both application of fluid power, some objects may need these types of pressures inorder to be made. Designers need to know if this is best way for them to manufacture the object or product.
