Miscellaneous Flashcards
Outline how computer aided inspection can be used to ensure a high degree of accuracy in the printing process
Measure colour with a densitometer
Check for colour density/hickies
Check for alignment/registration marks
Provides immediate feedback
Structure of foil line board
- Used as an insulator
- Protection from leaks
- Prevention of products expiring too quickly
1st layer- aluminium foil
2nd layer- inner ply
3rd layer- middle ply
4th layer- back coating
Risk assessments
Identify the hazard/ risk Identify the people at risk Evaluate the risk Apply PPE/ signage Record the risk Set a review date
Discuss how TQM can improve the quality of a product?
- makes a product ‘right first time’
- reduces OST of wastage
- covers all aspects of design and manufacturing
- records are kept
- increases customer satisfaction
- increase quality - increase costs
- employees may be resistant to change
- expensive to set up
Why continuous production for steel cans (beans)
- high demand of product
- 24/7 production
- authors mated equipment for manufacturing
- automatically checks quality
- allows the cans to be exactly the same (size and shape)
- reduces human error
Features of a mould which must be considered in order to create a successful vacuum forming
- tapered angles
- rounded edges
- air holes
- take care in positioning, to advising webbing
- no undercuts
- Durable mould
Discuss why you would use rapid prototyping using CAD/CAM as an alternative to block moulding
- RPT can be done extremely quickly
- reducing lead time and money
- RPT models can be made very accurately - reduces human error
- RPT can be made with intricate detail
- RPT allows for a more realistic model
Piezoelectric
Materials which produce an electric current when force is applied - eg. Sounds in a card when it opens - eg. Flashing lights in shoes •small amounts of energy is released •TRANDUCER: converts •ACTUTATOR: switch
RFID
- allows a product to be tracked
- placed into a product - be able to find in store
- rags can be built into products easily
- shows recycling info
- reduces time in finding the product
- acts as an anti theft device
- used for identification
- expensive to tag all products
- is simple to install
- ACTIVE: battery- can last over a longer range
- PASSIVE: receives only - Only works over short distances
Advantages of waste pulp for producing paper
- more environmentally friendly
- reduces the need to cut down trees
- reduces the amount of waste paper in land fills
- less chemicals are needed
- fewer greenhouse gases released
- it is more cost effective
Outline the role of international standards organisation (ISO)
- ensures a product is of the highest quality
- works alongside BSI standards
- sets international standards
- sets company standards
- ensures a product is fit and safe for use
- produces technical reports to communicate quality standards
Disadvantages of waste pulp for producing paper
- Large amounts of energy to produce
- paper can only be recycled 6 times
- paper needs to be de-inked
- glues/staples need to be removed
- waste produced by de-ink goes to landfills
- there’s less strength
- less durable
- discoloured
- poor quality for printing
Liquid Crystal Display technology
- lightweight
- no warm up time
- less space/ smaller
- higher quality/ higher definition/higher resolution
- better for your eyes
- expensive to replace
- limited viewing angles
- image persistence (ghosting)
- doesn’t get hot
Why is screen printing not suitable for large batches?
- time consuming
- ink needs to dry
- layers need to be applied individually
- only suitable for small/one of batches
- unable to print find detail
- there are more efficient methods
- stencils can be expensive
- colour can not be consistent - not of a high quality
Evaluate solid model
- photo realistic
- clear communication
- complex data required
- computerised- altered easily
