Design & Technology Health and safety
Test Bite 1. All those involved in product manufacture have a responsibility to use safe working techniques in order to avoid harming: The product The reputation of the company Themselves Other people Themselves and others
2. Which one of the following is NOT a workplace health and safety issue? Safety of the finished product when disposed of after use Safe storage and use of tools and equipment Safe storage and use of materials, chemicals, finishes and solvents Safety in the use of flammable and toxic substances All of these health and safety issues need to be considered
3. The passage below outlines how product design should consider the safety of the user of the product. Pick the correct words out of the list below and insert them into the text: tasty cheap enough hazards during precious bits dismantled after toxic suitable. A designer needs to consider the following two aspects of health and safety during product design. First, product design should take into account the safety of the finished product when it is used. For example, are all materials
for the purpose, and are all the suitably guarded? Second, product design should take into account the safety of the
finished product when disposed of
use. For example, will any
or harmful substances be released when the product is or recycled?

Read about plastics below and then answer the questions about them. Plastics – You need to find out about the characteristics of materials which could be used to make your design, including how you could shape them and form them. One material you could use is plastic, it can be bright colours and be durable. There are 2 main types of plastic; Thermoplastics (melt when heated), and Thermosetting plastics (which can be heated and heated and they will not melt.)
Thermoplastics Acrylic (Perspex) Good impact strength and can be seen through, lots of colours, 2 to 6mm thick, comes in big sheets, usually shiny on both sides. Goggles, lenses windscreens. Polystyrene – Easy to use. A wide range of colours available. light fittings, vending cups, packaging trays. PVC Polyvinyl chloride. – Inexpensive, can be rigid or flexible. Signs, hose pipes, cable insulation. 1.
Thermosetting plastics. Polyester Resin – strong when reinforced with glass fibre. Mouldings for boat hulls, car bodies. Epoxy Resin – Used to make glues (Araldite) which sticks most things.

Carefully read the information below which describes the manufacturing process called INJECTION MOULDING. About 70% of the plastic things in your house are made this way.
INJECTION MOULDING This is a very widespread, highly automated process that is used to produce a vast range of everyday items, including telephones, toys, buckets, bowls and cases for numerous household electrical goods from food processors to television sets. It is a process best suited to thermoplastics, but a few thermosetting plastics are also manufactured using injection moulding techniques. The process is quite simple. Plastic, heated to a plastic state, is injected under pressure into an enclosed mould. The mould is then opened up and the product removed. Injection moulded products are of a high quality and usually require no further finishing. The injection moulding machine consists of an injection unit and a mould. A hopper of plastic granules feeds a rotating screw mechanism which drives the granules towards the heater. The plastic then becomes plasticised by heat from a cylindrical heater and the rotating screw forces the plastic into a forward chamber. The screw mechanism is then pushed along the tube like a ram, injecting the plastic into the mould. The mould is subsequently cooled and opened to remove the completed moulding.
Now answer the following questions about injection moulding. Write your answers on the back of this sheet. 1. Draw FIVE items made by Injection Moulding. 2. In what form is the plastic fed into an injection moulding machine? 3. How is the plastic moved towards the heater? 4. How is the plastic forced into the mould? 5. What kind of plastics are best suited to being shaped by injection moulding? Why is this? 6. Explain the statement at the end of the second paragraph "…...are of a high quality and usually require no further finishing." 7. Which part of your product are you making using injection moulding?

Manufactured Boards Manufactured board are made by cutting up solid timber and sticking it back together again in a different way. Although this sounds strange it is a good way of making large , flat boards . Large boards cut directly from a tree trunk are quite strong but they will not stay flat. Using the drawings at the side and the words at the bottom of the page fill in the missing gaps. _________ is made by sticking together many thin layers of wood called veneers. Each layer has its _______ in the opposite direction to the ones next to it. This makes the boards strong, it is used for things like drawer bottoms, toys, and interior doors. It is usually very _____ . ___________ is made by gluing and compressing pulped wood. One side is rough and the other side is ______. It comes in this sheets and can be used in cupboard backs. It is not very strong. __________ is made by ________ and compressing together thousands of tiny bits of wood. It is not very strong and is difficult to join. It is often used for ________ modern furniture. __________ is made by glueing strips of softwood side by side and then sticking a veneer of each side. It is very strong and is often used for making furniture with a ___________ veneer on the surface There is one manufactured board that has not been mentioned. In the space below write the name of the

Read about woods below and then answer the questions about them. Hardwoods – are harder and heavier
than softwoods. They come from many parts of the world and in many different colours. Use – Hardwoods are used for high quality work like furniture. Examples – Mahogany is reddish brown in colour and is both hard and strong, it is often used for top quality furniture. Beech is pinkish brown with small gold flecks. It is used for mallets, workbenches, wooden kitchen tools and some school furniture.
Softwoods – are softer, easier to cut and not as hard wearing as hardwoods. They grow faster and are usually lighter in colour. Softwoods are cheaper than hardwoods, they are used a lot in the building industry for roofs and window frames. Examples – Parana pine is pale yellow with reddish brown streaks, it is often used for good quality joinery such as staircases. Redwood is honey coloured with very definite grain and lots of knots. It is used a lot for house roofs, window frames and skirting boards.
Manufactured boards – are made by cutting up solid timber and sticking it back together in a different way. Advantages – a good way of making large flat boards (large boards cut directly from a tree are quite strong but they will not stay fat, they twist or warp). Examples – Plywood is made by sticking together thin layers of wood called veneers. Each layer ahs its grain in the opposite direction to the one above or below it. This makes the wood very strong. Chipboard is made by gluing and compressing together thousands of tiny bits of wood. It is cheap but not very strong and is difficult to join, we don’t use in school. MDF medium density fibreboard is made by gluing and compressing pulped wood. Both sides are smooth and it comes in 3, 6, 9, and 18mm thick sheets, it is used for all sorts of things in and out of school from furniture to picture frames.

Looking at Timbers Although there are hundreds of different types of trees, there are just two types: deciduous trees and conifers. Deciduous trees Deciduous trees have broad leaves which they shed in the winter. they grow mainly in the warmer regions of the earth and have their seeds in fruit. They produce timber known as hardwood. The majority of hardwoods are hard by nature, but there are exceptions with balsa wood being one of them. This is often used to make model aircraft because it has a low density (lightweight). Conifers Conifers are usually ‘evergreen’ with needle– like leaves. They grow mainly in the cooler regions of the earth and produce the timber known as softwood. Their seeds are in cones. The majority of softwoods are easy to work with and are relatively much cheaper to buy than hardwoods. 1) Give one example of a softwood you have used in school
.................................
2) What have you learnt about the material you have used above? State some of its properties.
3) Find one example, at home, of a piece of furniture which you feel is made of either hardwood or softwood.
