Production Aids, Material Selection and Stock Forms Flashcards
What do manufacturers have to think about before using a material
Functionality, Ethical Factors, Availability, Aesthetics, Cost, Social/cultural factors.
what is functionality
how well a product does its job
what is ethical factors
the moral decisions when manufacturing products
what is availability
ease of sourcing and purchasing material. is it in good supply? could this affect the cost?
what is aesthetics
how a product will look. Does it look nice? appropriate? Is the finish cost-effective?
what is cost in terms of material selection
The cost of materials and manufacture. Could you buy a different material that costs less and still does its function?
social/cultural factors what is it
social responsibility and a sensitivity to other cultures. Has the material we use been sourced from a renewable supply?
what are raw materials
unprocessed materials to produce a variety of products. in spite of this, the materials or components must be in stock for business and have shipped to their company
what is a stock form
materials that are supplied in many common shapes The use of an appropriate stock form will keep down costs and avoid the need for any additional machining or processing before use. Having different sizes or products also helps the buyer to select which sizes/shapes they need
difference between reused and recycled metals
Most products, including metals, are recycled. This simply means that they are broken down and changed into a different product linked to that material.
however reused is not being changed to its raw original form and being reused in a different way but in a same material
examples of metal stock forms
flatstrip, roundbar, hexagon bar, rectangular tube, channel, angle, sheet, round tube
examples of plastic stock forms
sheets, granules (moulding) ( raw material ), powders, foams, films, PLA filament (idek)
what is a production aid
usually manufacturing many products and a short amount of time is really intensive so they use a variety of different aides to help it speed up the process
what are templates
something to draw or cut around to produce a shape identical to it. A template is a tool used to mark out shapes repeatedly. For example, if 100 acrylic keyrings are all to be shaped so they are the same, a template could be made to draw around for speed and consistency.
- can be used in a commercial and one off manufacture
- can be copied by hand and through CAD
- helps to ensure the quality of the product in the outcome
Moulds and formers
a hollow shape used when casting metal or a plastic resin (moulds) . a former is a rigid shape that is used so that other materials take its form. A soft material is stuck in a position where its heated up and bended fully. when its hardened it is then removed leaving the mould ready to be used again
