The process of manufacturing is all about creating new materials by application of tools, raw materials, labour and utilising technologies. Different materials manufacturers use different methods for producing a number of materials handling products. Rotational moulding technology is one of the most preferred technologies when it comes to production of a wide range of articles in plastic.
Rotational moulding is a technology in which very large and hollow pieces of materials can be produced with tremendous flexibility. This technique was used for the first time by ancient Egyptians for casting ceramic. It has travelled a long way since then and has evolved to be one of the most versatile and simple process of fabrication. The requirements are very basic- resin and a hollow mould. This mould undergoes bi-axial rotation after the resin is injected to it- molten resin distributes itself in the mould under rotational gradient. This is the reason behind exceptional uniformity in wall thickness of the materials produced in this way. A number of different rotomoulding (as it is generally called) methods are in use. The most common of all of them is injection method which is used in production of high tolerance components. In reaction injection method chemical reactions cure the resin- automotive parts, manufacturing enclosures are produced in this way. Fibre optics, pipes are manufactured by extrusion rotational moulding and vacuum foaming process is the most suitable in production of product packaging, speaker casings etc.
Among all the services provided by materials manufacturers, the most significant is production of various articles either in part or in whole. They rely on different pathways for such production. In mass production process, a complex task is broken down in several simple steps which are subsequently handled as per production regulations. Repetitive production of one particular unit over appreciably long period of time is done in this way. After production of the necessary parts, assembly line is used to put the final material in shape.
Material manufacturers prefer to use batch method when it involves production of a number of good but all in relatively smaller quantity. It not only saves precious time but also demands less storage space- the resulting articles are high in precision. The in process work turns out to be the inventory in job shop method of manufacturing- it requires the least number of machines for production but at the same time demands a little complicated planning.
Besides producing goods and taking care of their storage and shipping, another very important service provided by manufacturers is assembling pre-manufactured components in order to give the final shape to a produce. It happens very often that several components manufactured at different locations are gathered at a particular location where the expertise and infrastructure required for the desired job is available- the assembled product is rolled out by the manufacturer from that site. This is a very popular method because reduces production cost drastically. Thus both rotational moulding and efficient methods used by materials manufacturers give us improved products.
