What is one off production?
The manufacture of a single product or item which usually requires the use of highy skilled employees during the making process.
1 of 61
Eaxmples of one off production
Large scale projects like ships, multi-story buildings, bridges and stadiums. Small scale projects like Bespoke furniture, jewellery and made to measure clothing.
2 of 61
What are the characteristics of one off production?
Small specialist companies, a skilled workforce, the use of specialist materials, high quality and expensive products made due to the level of skill needed during production
3 of 61
What is Batch production?
When thousands of the same product are produced along a production line
4 of 61
Examples of Batch production
Special edition cars, garden furniture and socks.
5 of 61
What are the characteristics of batch production?
Produced on a production line, Flexible workforce, one task for each stage along the production line and the line can also manufacture other products aswell.
6 of 61

15 of 61
Define the thermal properties of textiles
clothing is used as a thermal insulation, which is the reduction of heat transfer between the body and air. this works by trapping a layer of hot air close to the body to provide warmth
16 of 61
Explain how this property is used in the design and manufacture of products
Thermal insulation can work in the reverse aswell. FireFighter suits are made of Nomex becuase it has excellent thermal, chemical and radiation resistance for a polymer material which helps to protect the people inside the suits
17 of 61
Define the conductive properties of metals
Conductivity is the measure of how well a material allows an electrical currentt o pass through. metals are good conductors due to free electrons which are able to move freely which causes more collisions, passing on the electrical charge
18 of 61
Explain how this property is used in the design and manufacture of products
Copper is used in the manufacture of wires dues to its ability to conduct electricity. it has the highest electrical conductivity rating of all non precious metals making it the most suitable for the product.

20 of 61
Describe an area where ict is used effectivly within manufacturing
Printed Circuit Board layout has been designed using CAD the board can be produced or manufacturedusing CAM. The PCB is printed on to acetate then transferred to a copper clad board using the photo transfer method
21 of 61
Describe another area where ict is used within desiging
Computer Aided Design software can be used in the design process to design the structure or the housing of control systems for example. This makes the designs more accurate than hand drawn ones and also reduces human error.

Describe a hazard?
A hazard is an activity that is potentially dangerous. Once identified the risk of an employee being harmed by the hazard is worked out. The risk is then recorded as low, medium or high risk.

What is Durability?
A materials ability or product to last a long time
27 of 61
What does Morphological analysis mean?
Developed by Fritz Zwicky for exploring all the possible solutions to a multi-dimensional, non-quantified computer problem. the system allows for reduction by identifying the possible solutions that actually exist within a seemingly complex design
28 of 61
What is Lateral Thinking?
This is a way of solving problems by using reasoning that is not immediately obvious
29 of 61
What is Disassembly/ Attribute Analysis?
When existing products are taken apart and reviewed in order to see flaws/ how it works or to compare to the product in design stages
30 of 61
What is Structural Technology?
This is the technology of putting parts and materials together to create supports, containers, shelters e
