Objective: To understand about scales of production. Products are made in a variety of different quantities and these are known as scales of production. There are four different types:: One off production Batch production Mass production Continuous production

Objective: To understand about scales of production. One off production Only one of the product is made for a specific purpose, e.g a wedding cake. All the costs for designing, manufacturing and transportation are charged for this one product so costs are high and production is slow. Batch production These products are identical and are made in batches of pre determined numbers. Once the first batch has been produced a second batch is manufactured using the same tools and equipment. E.g Magazines, pasties. Employees may carry out a variety of tasks in manufacture and the use of Jigs and templates would be used to speed processes up. Mass production The product goes through many stages of a production line. The workers and the machines are responsible for only certain parts. Cost of the plant is high. Continuous production Products are produced over periods of hours, days, weeks or even years. The production line never stops. Few workers required and skill range is low. Cut these out and stick ‘em in

Objective: To understand about scales of production. Arrange the pictures to the descriptions

Objective: To understand about organising production. Scales of production: Just in time production: With lots of options available for products the manufacture has to be organised so that all the parts come together when they are required this also means that the company doesn’t have to store lots of goods. Jit involves working closely with the suppliers. The leather company making the seats need to know what colour is needed and when for. Each company needs to match their manufacture and delivery to the order time, this is called logistics. Ict is used to help information be shared. E.G if you order an Oak Green Golf, with a 2l 16v petrol engine and a grey leather interior then all the parts have to be ordered to the production line in time as the rest of the construction starts. After all the production line cant stop just because the engine hasn’t arrived yet. Copy this into your book.

Objective: To understand about organising production. Scales of production: Advantages of JIT: Less money tied up in storage. Disadvantage: Late delivery of goods stops the production line. Copy this into your book.

Objective: To understand about organising production. Copy this into your book. All these parts have to come together at one time

Objective: To understand about organising production. EDI (Electronic data interchange) This is the transfer of structured data with out human interference. This can shorten the supply chain by speeding up the time given to initiate and agree customer orders. A tee shirt is sold in a shop, a stock order goes direct to the manufacturer, the items are totalled up and collected by a delivery firm and delivered to the shop.

Objective: To understand about organising production. Managing stock: This is very important to commercial production: If there is not enough stock available, products cant be sold. There will also be a delay on ordering and receiving new stock. This can man that the customer might go elsewhere rather than wait.. Too much stock and it takes up space waiting to be sold and the risk of damage is increased. This is particularly important with food. http://www.youtube.com/watch?v=R4pN50yYI5k What does a warehouse look like, think of ikea. Cut out and stick in the image from pg 60.

Objective: To understand about mechanical properties Plasticity: The ability of a material to be perminently changed in shape. An example is melting a material into liquid form and pouring it into a mould. Elasticity: this is the ability of the material to bend and flex when force is applied and then return to shape. Strength: The ability to withstand force without breaking or deforming. Hardness: How resistant a material is to wear. Often specified for high wear areas like public places. Toughness: A materials ability to resist sudden impacts before breaking. Durability: A materials resistance to wear and tear and its resistant to corrosion and deterioration. All resistant or compliant materials share these properties but in different combinations. A designer will choose a material that is high in the property they require. Copy these into your book

Objective: To understand about different types of wood Wood comes in two main types and then split off from there: Natural Wood Comes in two types. Hardwood and soft wood. Hardwood trees loose their leaves in the winter generally and grow more slowly. This makes them more expensive Softwood (like Christmas trees) don’t loose their leaves in the winter and grow more quickly. Designers choose the type of wood on colour and pattern of the grain as this varies dramatically.

Objective: To understand about different types of wood Manufactured wood. Manmade and consists of woods being glued together either in layers or fibres. As a result of this they can be manufactured in very large sheets. Offer consistency in strength and workability. MDF: Wood dust and resin pressed together Plywood: Thin layers of wood glued at right angles. Chipboard: Made from small chips glued with resins and compressed. Blockboard: Core soft wood strips clued and covered with plywood on both sides. Hardboard: wood fibres that have been pulped and compressed.

Objective: To understand about manipulating and combining materials Paper and board: Paper and board is very easy to manufacture and is very versatile. Combining this with different materials produces packaging for a variety of things e.g: Aseptic cartons. These contain: Cardboard 70%- A stable material with good heat resistance, light protection and can be easily printed. Polythene Film 24%- Waterproof and seals well. Aluminium foil 6%- Excellent gas, water and light barrier (particularly when laminated between plastic layers). The combination of these properties makes Aseptic cartons very popular for products such as Fruit Juice, Milk and Soups. However it is hard to recycle. Copy this into your book

Objective: To understand about manipulating and combining materials Timber based products: Timber is very versatile but it does have limitations. The biggest one being the sizes that it comes in. As a result manufactured boards have been and are being developed to address these issues whilst retaining the appearance of natural wood. Copy this into your book

Objective: To understand about manipulating and combining materials Manufactured board comes in very large sheets and is generally from recycled materials. However they are unattractive and so they have a decorative layer of ‘veneer’ on top. The use of veneers makes the wood cheaper as the quantity of ‘real’ wood is greatly reduced. A veneer is term given to thin layers of wood approximately 0.8mm thick. This is widely used by companies like IKEA. A plastic laminate can also be used particularly for kitchen worktops. These are layers of paper in a plastic resin. The paper gives a decorative finish and the resin makes it hardwearing, heat resistant coating. Copy this into your book

Objective: To understand about metal and plastic based products and composite materials. Metal based materials: Non ferrous metals have a protective layer to prevent corrosion. Ferrous metals, with the exception of stainless steel, rust. There are several methods that can be used to stop this: Link these products to the process on the next slide: Cans of Tomato soup Mk2 VW Golf bodies Bathroom taps Outdoor bracket Jewellery Copy this into your book

Objective: To understand about metal and plastic based products and composite materials. Electroplating: Chrome. Another metal is used to coat the base metal. The coating material as well as preventing corrosion gives the base material a more attractive appearance. Enamelling: This is the process of coating ferrous and non ferrous metal with a layer of ground glass. It creates a hard and decorative and coloured coating that when used with steel, is hard and scratch resistant. Often used for coating cookers. Zinc plating: Steel is dipped into molten zinc. This is called galvanising. Plastic coating: Applying a thermoplastic coating to the surface of a metal item to provide long term corrosion, impact and chemical resistance Tin Plating: Steel sheets are passed through tanks of molten tin. The food industry use this. Copy this into your book

Objective: To understand about metal and plastic based products and composite materials. What process would you choose for these products?

Objective: To understand about metal and plastic based products and composite materials. Plastic based materials Plastic are largely synthetic or manufactured materials so can be easily processed to provide a wide range of different properties. Plasticisers can be used to improve the flow properties when injection moulding. Flame retardants are often used to produce a plastic that is resistant to combustion. Additives can be added to make plastic more biodegradable. Bio plastics are also available and these are made entirely out of renewable materials, wheat, corn and potatoes. Copy this into your book

Objective: To understand about smart materials and smart systems. Photo chromic: Materials change colour in response to light. Some glasses use reactive lenses which become darker as the light levels increase. Thermo chromic: These materials change colour in response to temperature. This has been used to manufacture bath plugs that show you when the bath temperature is too hot. Electroluminescent: Produces light of different colours when an electric current is passed through them. Used to illuminate emergency exits in buildings. Shape memory alloys: After being strained they revert back to their original shape at a certain temperature. Example would be memoflex glasses. Fluorescent: Materials produce light when exposed to uv rays. When uv is removed the light goes out. Quantum tunnelling composites: These have been used to create touch sensitive switches for electronic devices in clothing. Cut these out.

Objective: To understand about smart materials and smart systems. Thermo electric materials: When a current is applied one side of the material cools whilst the other side heats up. A plate has been developed that uses this material to keep food either hot or cold depending on the polarity of the power source. Magneto-Rheological fluids: These become solid when placed in a magnetic field. They can be used to construct dampers that suppress vibrations in buildings during earth quakes or high winds. Cut these out.

Write these titles in your book and arrange the boxes you have just cut out to the correct titles: Colour changing materials Light emitting materials Moving materials Temperature changing materials Thickness changing materials. Once you think you have them right, check page 128-129 and glue them in the correct places. After this read ‘the future of smart materials and smart systems, and nanotechnology page 129. What are your thoughts?

Objective: To understand about modern materials Take page 130-131 and stick in the individual pictures and explanations. Answer question 1 and 2 at the bottom of 131. Do the same with 132 and 133

Objective: To understand about standard components These are pre manufactured parts brought in by individuals or commercial manufacturers usually as part of a batch or mass production system. This brings many benefits to the producer and the consumer, including, re direction in manufacturing costs, standard sizing, consistent quality. For example an mp3 player uses a standard mini usb socket to connect to a computer. The mini usb socket would be made by a factory who specialise in this component and would be then brought in by other mp3 player manufacturing companies. VW own, Volkswagen, Audi, Seat and Skoda. Although they appear different there are many shared parts between these ranges. Copy this into your book
