© Boardworks Ltd 20052 of 15 Learning objectives © Boardworks Ltd 20052 of 15 Learning objectives To understand how reforming and deforming processes change the shapes of materials. To know how to deform wood, metals and plastics. To know how to reform metals and plastics.
© Boardworks Ltd 20053 of 15 Deforming materials
© Boardworks Ltd 20054 of 15 Wood can be bent – gently and carefully! If you make small cuts part way through the wood it is easier to produce a curve. The process of making small cuts part way through the wood in this way is called kerfing. Deforming wood
© Boardworks Ltd 20055 of 15 Laminating
© Boardworks Ltd 20056 of 15 Thermoplastics can easily be bent when they are heated. Thermoplastics can be bent using the heated wire strip in a line bender or strip heater. Deforming plastics
© Boardworks Ltd 20057 of 15 Vacuum forming is a process which deforms thermoplastics into new shapes. Press play to see a video of the vacuum forming process. Deforming plastics
© Boardworks Ltd 20058 of 15 Vacuum forming Vacuum forming is often used to produce packaging items such as the insides of boxes of chocolates. A sheet of plastic is forced down over a mould to create the desired shape. The sides of the mould need to be tapered. Corners must be smooth curves so that the plastic does not get punctured. Holes are drilled to allow air to be extracted.

© Boardworks Ltd 200510 of 15 Metals can be beaten or folded to change their shapes. The process of re-shaping metal in this way is called deforming. Mild steel sheet being bent into an angled shape. Copper being beaten with a hammer into a curved shape. Deforming metal
© Boardworks Ltd 200511 of 15 Reforming plastics
© Boardworks Ltd 200512 of 15 Sand casting Reforming metals – casting Metals are reformed using casting processes. There are two main types of casting: Die casting can be done in schools uses an aluminium alloy that has a low melting point is labour intensive. is used in industry uses metal moulds which are expensive but re-usable is very accurate and quick is expensive to initially set up.
© Boardworks Ltd 200513 of 15 Sand casting
© Boardworks Ltd 200514 of 15 Die casting is used in industry for producing large quantities of very accurate castings for machinery such as engines. Die casting The molten metal is forced into the mould by a piston. It is then cooled before the mould is opened.
© Boardworks Ltd 200515 of 15 Key points © Boardworks Ltd 200515 of 15 Key points Deforming involves changing the shape of a material by bending, squashing, heating or bending. Reforming involves melting a material before making it into a new shape. Wood can be curved using a kerfing technique or by laminating strips of wood to produce plywood. Thermoplastics can be bent using a line bender or strip heater. They can also be deformed using vacuum forming and blow moulding processes. Plastics can be reformed using injection moulding. Metals can be bent or folded, and reformed using sand or die casting processes.
