Plastic manufacturing company in uae| Plastics have polymer as the main ingredient and are a range of synthetic and semi-synthetic materials. They have plasticity properties and can be easily moulded, pressed and extruded. They are widely used due to their durable, flexible and lightweight properties. Also, they are inexpensive to manufacture.
Plastic is manufactured in industrial plants and derived from fossil-fuel-based compounds. They can be classified based on their chemical structure. They can also be classified based on the qualities relevant to manufacturing like thermoplastics, thermosets, amorphous, crystalline, conductive polymers and biodegradable plastics. The different processes used by plastic manufacturing company in UAE are blow moulding, injection moulding, extrusion, rotational moulding and compression moulding. Blow moulding is used to produce hollow products like bottles or containers. In this process, hot air is blown through a pre-formed tube called a parison which is made up of semi-molten plastic. The plastic expands and fills the mould cavity. Injection moulding is used to make complex shapes like medical components. It is used to make products in large numbers like Lego, plastic cutlery, machine housings and more. In this process, the plastic is injected into the mould to get the desired shape. Extrusion is used to make products with a constant cross-section like fibres, tubes, pipes, sheets, films and more. In this process, plastic pellets are added to a heated cylinder and driven forward by a turning screw. The plastic melts and is forced through a dye at the end creating continuous lengths of shape. Rotational moulding is used to make products with uniform wall thickness where the inner surface of the products can be inferior to the outer surface. It is used to make storage tanks and traffic bollards. Compression moulding is used to make products like plugs, sockets, radios and telephone housing, tableware, ashtrays and more. In this process, a measured amount of plastic is added to the two-part mould and subjected to heat and pressure. Types of plastics Thermoplastic These are polyethylene and polystyrene and can be moulded and remoulded repeatedly. The chemical structure contains individual molecules that are separated and flow from one another. They may be linear or branched in structure and may have low or high molecular weight. Thermosetters These cannot be reprocessed upon heating. Once they solidify into a shape they stay solid. When heated thermosets decompose rather than melt. Even if it is heated repeatedly it does not soften to a point where it can be reworked. The other types of plastics are amorphous plastics, crystalline plastics, conductive polymers and biodegradable plastics. Amorphous plastics do not have an ordered molecular structure. Crystalline plastics have a pattern of regularly spaced atoms. Conductive polymers can conduct electricity. Biodegradable plastics break down upon exposure to sunlight.
