Research task 1: Metal Casting Casting is a manufacturing process by which a liquid material is usually poured into a mould, which contains a hollow cavity of the desired shape, and then allowed to solidify.manufacturingmould The casting process is one of the oldest known with evidence of copper casting being carried out as early as 3200BC. Materials that can be cast include some metals, plastics, wax, resins, glass, clay and concrete. The mould can be made from different materials including sand, rubber, cuttlefish, graphite and plaster. In a school workshop, the most commonly casted materials are aluminium and pewter. This is because these metals melt at low temperatures making them easier to work with than metals which have high melting points.
Task 1: Pewter Casting Task: Using a piece of cuttlefish create a mould and cast a small piece of pewter Learn: To create a mould How to cast pewter Designing Outcome 1.2Researching the main design factors identified, using a range of appropriate techniques Materials & Manufacture 1.1 Selecting potential materials to suit manufacturing tasks based on information given in working drawings and design proposals Materials & Manufacture 1.2 Testing the suitability of selected materials in terms of workability, practicability, function and performance
Research task 2: Tinwork A tinsmith, also known as a whitesmith, was usually a man, who made or repaired tin items. The practice of tinsmithing, or making and repairing items of tinplate grew from the early 1600s in the UK. Common items made were cups, plates, funnels, bowls and candleholders. Tinsmiths also worked with copper which has similar properties to tin. Until early 1700s tinsmithing was carried out by hand. Young boys where trained as apprentices for 6 years before they where fully qualified. Tin is a pure metal which can be mined. Tinplate is created in a process where thin steel is dipped multiple times into molten tin, thus plating it in tin. This process prevents the items from rusting. Alloys of tin include Bronze, Pewter and Solder. Working with Tin requires few tools, a pair of tinsnips, hammer, soldering iron and an anvil.
Task 2: Tinwork For this task you will be using aluminium rather than tin Task: Choose one of the designs and create a punched design on your piece of aluminium Learn: How to cut and shape aluminium How to punch a pattern into aluminium Designing Outcome 1.2Researching the main design factors identified, using a range of appropriate techniques Materials & Manufacture 1.1 Selecting potential materials to suit manufacturing tasks based on information given in working drawings and design proposals Materials & Manufacture 1.2 Testing the suitability of selected materials in terms of workability, practicability, function and performance
Research task 3: Wrought Iron work A Blacksmith makes many kinds of tools and other objects out of metal. He heats the metal in a forge to make it soft and then hammers it on an anvil to shape it. The metals used where bronze and iron. Iron is still used today but it is usually mixed with carbon to create steel. Metal was first forged over 4000 years ago in the middle east. From the 13 th century onwards with the advancement of technology Blacksmiths where able to make weapons, armour and tools and they became Kings of trade. Their own company was formed The Worshipful Company of Blacksmiths was formed in In 1496 the blast furnace was introduced which made it possible to process larger quantities of cast iron which was turned into wrought iron. The industrial revolution in the 1700s changed the way that metal was produced which led to the decline in the number of Blacksmiths. Today wrought iron is no longer produced. There are plastic and resin materials that are available that are much stronger and cheaper to produce.
Task 3:- Wrought Iron work As a class a piece of steel bar will be bent into a scroll using specialist bending tools. This will be too big a scale to incorporate into the mirror design so you will use a different material - copper wire for this task Task: Using the peg jig create a decorative bent metal shape by bending the copper wire around the pegs. Learn: How metal can be bent to create scrolls Designing Outcome 1.2Researching the main design factors identified, using a range of appropriate techniques Materials & Manufacture 1.1 Selecting potential materials to suit manufacturing tasks based on information given in working drawings and design proposals Materials & Manufacture 1.2 Testing the suitability of selected materials in terms of workability, practicability, function and performance
Research task 4: Riveting Rivets are made to put parts together permanently just like screws. They are used on heavy metalwork such as those found in bridges, locomotives, boilers, and boat hulls. Heavier rivets are made of mild steel. Lighter rivets are made of copper, brass, aluminum, nickel, silver, and tinned galvanized steel. Mild steel is also used for small rivets. The tools used for riveting are a solid punch, riveting hammer, and rivet set. The most commonly used hammer is the ballpeen hammer. A rivet set is a small bar of steel with a hole in one end to receive the end of the rivet and a cuplike depression used in forming the head of the rivet as it is hammered down. Although riveting was developed for fastening metalwork together, rivets are now used to hold nearly every type of material together, including fabric and plastic. Because of this, several different types of rivets have been developed for affixing different materials, and some of them are not appropriate for use in sheet metal work. The type of rivet metalworkers use depends upon the fastening situation and design specifications of the project. Rivets on an Aeroplane Rivets on a Steel Bridge Rivets used on Fashion items
Task 4:- Riveting Task: Join two pieces of metal together using a round head rivet and countersunk rivet Learn: To use rivets to join metals To create a round head and how to countersink a rivet Designing Outcome 1.2Researching the main design factors identified, using a range of appropriate techniques Materials & Manufacture 1.1 Selecting potential materials to suit manufacturing tasks based on information given in working drawings and design proposals Materials & Manufacture 1.2 Testing the suitability of selected materials in terms of workability, practicability, function and performance
Research task 5: Metals Process Metallurgy is one of the oldest applied sciences. Its history can be traced back to 6000 BC. Currently there are 86 known metals. Metals account for about two thirds of all the elements and about 24% of the mass of the planet. Metals have useful properties including strength, ductility, high melting points, thermal and electrical conductivity, and toughness. From the periodic table, it can be seen that a large number of the elements are classified as being a metal. Some Common Metallic Materials Iron/Steel - Steel alloys are used for strength critical applications. Aluminum - Aluminum and its alloys are used because they are easy to form, readily available, inexpensive, and recyclable. Copper - Copper and copper alloys have a number of properties that make them useful, including high electrical and thermal conductivity, high ductility, and good corrosion resistance.
