Plastics are incredibly versatile and are widely used in everyday life ranging from common household items to their various uses in building and agricultural Light Industrial Building products. The first plastic was created as early as 1862 and since then, the types of plastics and their uses have multiplied significantly.
A plastic is a synthetic substance made from small organic molecules generally containing carbon and hydrogen with a mixture of other elements, e.g. oxygen, nitrogen or chlorine. These molecules join together to form polymers which can then be moulded into any shape. Plastics fall under two distinct categories; thermoplastics and thermosets. Thermoplastics are plastics which, once prepared, can be heated and reformed continuously, thus facilitating the recycling process. Thermosets, however, cannot be reformed and once set, cannot be remoulded.
There are many different types of plastics produced in plastic manufacturing companies across the globe. The end result depends on the additional elements added to the plastic during production. The resulting polymer will then hold its own distinguishing means of degradation and resistance to heat, chemicals and light.
There are many moulding processes performed by plastic suppliers including the plastic injection moulding and the plastic extrusion moulding processes. Injection moulding is the most common process whereby plastic pellets are fed into a large heated barrel where they are crushed and liquefied. The liquid is then propelled through a nozzle and into the mould and left to cool into its correct shape whilst pressure is applied to keep the plastic in place. This form of plastic manufacture results in everyday items such as household containers, bottle caps, one-piece chairs and tables and mechanical gears.
Another moulding technique applied by many plastic manufacturers is the extrusion process. This process is very similar to the injection moulding method but is used to produce hollow plastics such as tubes, straws and pipes etc. The same procedure applies as above but this time the liquid plastic is left to cool in a mould that contains a tube-like orifice. Once cool, the plastic is fed into an extruder which compresses the plastic into its final shape. This form of manufacturing produces high-impact resistant items such as car bumpers and surf boards, hoses, rods and fibres.
Plastics are also used to create large heavy duty items such as aircraft and car windscreens, vehicle doors and dash panels. The process of producing these large plastic sheets is through thermoforming. This is a far less forceful process then the injection What Is Industry Competition or extrusion moulding. The plastic is heated and moulded much like clay and is left to cool into the required position once finished. Although this method is a lot less expensive it is fairly limited as fewer shapes are possible to create.…
