QA And QC Flashcards
What is Quality Assurance (QA)?
Maintains the quality manufacturing processes and systems.
Quality Assurance does not check the quality of the final product, but the quality of all systems on the production line, staff training and quality monitoring.
What is the lion mark?
The Lion Mark is a British consumer symbol developed in 1988 by British Toy & Hobby Association (BTHA) and used to identify toys denoted as safe and of high quality.
What is the BSI kite?
The Kitemark is a UK product and service quality trade mark which is owned and operated by the British Standards Institution (BSI Group).
The Kitemark is most frequently used to identify products where safety is paramount, such as crash helmets, smoke alarms and flood defences.
What is Quality Control (QC)?
Ensures the quality of a product through regular testing.
The process of inspecting products to ensure that they meet the required quality standards. It may take part in any part of the production.
What are Jigs?
A device you line material up to accurately repeat an operation accurately time after time e.g. for sawing, cutting, drilling, punching.
What are moulds?
A shaped cavity used in which a liquid can be poured until it solidifies or cools e.g. jelly making, aluminium casting, slip casting
What are formers?
A construction used to help with shaping operations e.g. laminating, vacuum forming, acrylic bending, felt blocking, dressmaker’s dummy, drop moulding & drape forming in clay.
What are tolerances?
The acceptable range of differences from the agreed standard.
What are the different scales of production?
● One off production
● Batch production
● Mass production
● Continuous production
● Just in time production (JIT)
What is ‘one off production’?
These products are expensive at cost price, sometimes bespoke, and often take a long time to make and cost of materials & labour are high. Many prototypes are ‘one off products’.
Are often made by hand by skilled craftspeople.
What is ‘batch production’?
These products are identical and produced in small batches, daily, weekly, monthly or when needed. They can range in cost priced. Production normally runs from between 2 - 10k.
What is ‘mass production’?
These products are produced in very high volumes, 10k +. They are normally products that are in high demand and can range in expense, cars are a good example.
What is ‘continuous production’?
These items are normally very cheap to but make and could be considered ‘throwaway’. These factories are often found in developing countries where land for factories and equipment
are cheaper.
What is ‘just in time production (JIT)’?
This scale of production relies on the product been manufactured to a time schedule. This allows raw materials to be delivered at an exact time for production and then manufactured and are shipped straight to distribution /retailers. Apple INC uses JIT production.
