What is Rotational Moulding
Rotational moulding is the process of manufacturing hollow plastic parts/products such as garden planters, water butts or canoes. Rotational moulding, produces strong durable products that resised the weather and can last many years. The end product is availalbe The process involves high temperatures of heat which melt the Meduim Density Polyethylene (MDPE) into a substance that can then be moulded to any shape.
Charging the mould
A predetremind amount of plastic (either in powdered or liquid form) is poured into a hollow metal mould which is made from either Cast iron or Aluminium. The amount of plastic used in the metal mould will be equivilent to the weight of the finished product. Rotational moulding has one big advantage of no waste. All the plastic poured into the mould is used.
Turning up the heat
Once the plastic has been poured in, the second half of the mould needs to be securly clamped into position. The mould is then moved into the heat source where the rotation starts. Rotations are normally around 10-12 rev min, this is so all the plastic is dispersed equally. Also aswell as rotating the mould will end start to tilt on its second axes. By changing the speed of revoltions and tilts, its is possible to control the thickness of the walls of the end product. If you use a ratio of 4:1 on the speeds of two axes, this should create an even wall thickness.
Cooling down
After the heating cycling is complete, the mould is removed from the oven and the cooling cycle begins. This involves using air blows and fine mists of water to slowy cool the mould. If the mould is cool too quickly the product mey become distroted. Once the moulding is complete, it now needs to be cooled. Most machines will have large fans/blowers at the bottom of the machine, they may also have cooling water sprays. The water is used in short sperts, so the mould cools evenly. When the product is cooling, it starts to shrink away from the steel mould. Once cooled, if the adequte draft angles have been provided then the product should slide out. Release agents are used easy this process.
Rotational Moulding Materials
To create a mould or tool for Rotational Moulding, it would have to be made from the folllowing materials
- Sheet Steel
- Aluminium
- Electroformed Nickel
Sheet Steel
To fabricate the sheet metal into a mould, various methods such as metal shaping and arc welding is usually satisfactory for most low volume applications. You can use low carbon steel if your volume of application is low, however if you a experiencing rust, then galvanized steel would be a good idea. If you forced to store your moulds outside, Stainless steel would be a good material to use.
Aluminium
Aluminium has better thermal conductivity than steel, however because aluminium is not a thick as steel, the walls of the mould need to be made thicker which will reduce the thermal activity. This means that heating up and cooling down cycles are slower than steel moulds.
Electroformed Nickel
Electroformed nickel is used in moulds that require fine detail such as mannequin head.
