Exam mock 2 questions Flashcards
Why is rotational modelling suitable?
-Produces seamless, hollow objects that need a large wall thickness.
-Used when blow moulding is not suitable as the walls of the product would be too thin and make it weak.
-Set up costs are high so it is only suitable for large scale production.
Annodising?
-It enhances the natural oxide layer resulting in increased hardness and toughness.
-Can provide colour to also enhance the aesthetics of the product.
-Anodised products can then be finished with a varnish to add further protection.
-
Embossing?
-Creates a raised design on the surface of the card.
-It adds a visual and tactile effect.
Foil blocking?
-Metallic foil is used to add an area of depth and texture to the product.
Spot varnishing?
-It only adds varnish to a specific area.
-In order to enhance the colour.
Case hardening?
-Increases surface hardness and resistance to indentation.
-The inner core retains to original properties.
Gold?
-Corrosion resistance
-Malleable
Gel coat?
-Mixed with a pigment to add colour to the coating.
-Add additives to prevent degradation.
Open design?
-Operates without the use of patents, so designs can be freely accessed by everyone.
-More people can use and access designs so time to manufacture is often quicker.
-Allows the designs to reach people with a range of skills who can implement their experience more easily into the manufacture.
-Gaining more opinions from a range of people is likely to produce a product that suits the majority.
Vertical in-house production?
-Reduction in the risk of unexpected price increases for components.
-Less susceptible to suppliers going out of business.
-Easier to implement their quality assurance strategies.
-Can reduce manufacture times, not waiting for deliveries of components.
-Have complete control over the product if you produce all the components, nobody else can take any credit.
Safety for the consumer?
-Can be no sharp edges or corners that could cause a hazard.
-Ensure that there are no small parts or small parts are securely attached so they wont lead to a choking hazard.
-
Vacuum forming?
-A mould is produced with a draft angle so that the polymer can be easily removed.
-The mould is placed on the bed of the machine.
-A polymer sheet is clamped over the mould and heat is applied.
-Once the polymer has softened the heat is removed and the mould is raised.
-The vacuum is switched on and the polymer is pulled over the mould.
-Once the polymer has cooled the vacuum is switched off and the mould is lowered.
-Excess polymer is then trimmed off.
Software updates?
-Keep the device protected from hackers.
-Take time to update which can annoy the consumer.
-Add new features that improve user experience.
-Remove obsolete features that clog up storge and slow the device down.
-
Teak?
-Good weather resistance which will prevent it from degrading when left outside.
-Can be steam bent to create the curved edges of the sunbed.
-Good toughness to resist the impact through general use when people sit on it.
-Good hardness to resist wear and tear again through general use.
-Has a straight grain wich is naturally attractive and no additional finishes are required.
FEA?
-The range of colours represents how much pressure is exerted on the bracket.
-Blue is where the least force is applied, and the red is where the most force is applied.
-Force the designer to reinforce the areas where the most force is applied.
-See which designs perform best under the same force.
3D printing?
-Colours
-Enviromennt
