All About Plastic

Plastic is a material that usually made up of synthetic material or semi-synthetic materials of organic nature. Plastic is usually malleable which means that the material can be moulded into different types of solids- in terms of shape and sizes. The plastic can be melted and moulded into different items without losing their initial properties. This makes them ideal for recycling, a process that also ensures that the environment is protected against irreversible damage brought about by plastic pollution.

Different manufacturers employ different methods in the manufacture and plastic moulding uk. accurate laser cutting can be used to cut the moulds as well as trim the final product for aesthetic value.

Moulding can be divided into different types including injection, casting, blow, compression and rotational moulding. Each method has its own advantages and disadvantages. Casting is the simplest form of moulding and includes the transfer of the molten plastic into a mould of a specific design and size. The plastic is then left to cool and the mould is removed.

For injection moulding, the liquid plastic is injected into a tightly closed and chilled mould. It is then left to set completely before the mould is removed to reveal a high quality three dimension object. Blow moulding on the other hand is used in the manufacture of hollow things such as pipes. A cold mould with a tube -- with a specific shape when inflated - is used. Air is blown into the tube when the plastic is still in liquid form. It is then left to cool before it is removed.

In rotational moulding, two mechanical arms which are constantly rotating hold the mould into place and as they rotate, the plastic coats the inside of the mould to create the desired object. It is used to create such things as storage tanks, furniture and toys. Compression moulding is only used for large scale production processes due to its complexity and labour intensiveness. It uses two moulds where molten plastic is poured into one mould then another mould is pressed into it. This shapes the plastic into the desired shape and design. The plastic is left to cool down before the mould is removed.

What products are made from plastic?

Plastic packaging bags, plastic bottles, pens, traffic cones, water tanks, carpets, kitchen utensils, cleaning items such as brushes, basins, dispensing bottles, different auto parts, medical equipment, toys, footwear, fabrics, files, telephone and mobile phones all have plastic components. In the medical world, they are also used to make implants and prosthetics making them utterly important. Every industry utilises plastic to make items used in day to day life. Its importance cannot go unnoticed in the modern world.

Why do people use plastic packaging?

One of the greatest advantage of plastic is that it can be moulded into any shape and size with ease. This makes it one of the most popular packaging materials on earth. Besides this, plastic does not transfer particles of any kind to the food or drinks packed therein making it also ideal for packaging. Plastic allows the items packaged therein to remain fresh and prevents water damage since they are impermeable to water, air and other fluids. In addition to this, plastic is cheap and affordable even to small businesses all over the world. Plastic also has the ability to be customised to specified characteristics making it possible to craft packaging to suit a brand or client needs.
