When there is a need to produce plastic parts, that is when the use of plastic injection appears. In various industries, they often produce plastic parts made of various polymers, which are actually the raw materials for the production of these parts. Each of the polymers are used in a field according to their chemical nature and properties.

Every industry uses plastic injection in such a way that, among them, the automobile industry, the airplane industry, the toy and household appliance industry, etc. In the following, we will examine several different industries to understand the application of plastic injection in that industry.

Application in home appliance industry
One of the important industries that deal with plastic injection is the home appliance manufacturing industry. Among the products that are created in this industry through the process of plastic injection, we can mention food storage containers, plastic containers, trash cans, food processors, plastic tools, etc., for the production of such products, polymers are used, which are the least expensive. They bring the rate of chemical reaction.

Application in water and sewage industry
The water and sewage industry is another industry that uses the plastic injection process to its advantage. One of the obvious examples is water pipes, which were used in the past using metal pipes, but nowadays they use PVC pipes with high strength and resistance. In addition, these pipes cost less to repair and replace than metal pipes and are easier to work with. It can be said that today most of the water pipes that have found their way to our homes were created through this plastic injection method.

Application of plastic injection in the toy industry
In the toy industry, you can produce all kinds of dolls with fine details through the plastic injection process. It can be said that nowadays all dolls are created through plastic injection because this method allows you to produce the most delicate and at the same time the softest plastic parts in high circulation.

The use of plastic injection in the automotive industry
If you have seen it, you will realize that almost 80% of the parts of a car are made of plastic. Since these parts are related to people’s lives and work, they must have sufficient strength and have good quality. Therefore, these plastic parts cannot be produced by any method and must be made in the best way.

The use of plastic injection method makes sense here. In the automotive industry, 13 types of special polymers are usually used for plastic injection, the most important of which are polypropylene, polyurethane, PVC, etc. Lamp housings, safety guards, mirror frames, windows, etc. are used.

The application of plastic injection in the aircraft industry
An aircraft can perform well at high altitudes when it is designed and composed of light yet delicate components. These parts must be produced in such a way that they are flexible against air pressure and weather changes and show high resistance. Therefore, in the aircraft industry, polymers such as polyamide imide, polychlorotrifluoroethylene, polytetrafluoroethylene, etc. are used in the plastic injection process to produce products such as containers, housings, panels, lenses, and other aircraft parts.

Application in military industries
Plastic is also widely used in the military industry. Among its uses, we can mention the manufacture of gun bodies, vests, protective and security clothes, etc. If we want to name the most important constructions of the military industry that are produced through the plastic injection method, we should mention the military connectors or connectors, which can last in the harshest weather and environmental conditions.

The use of plastic injection in the packaging industry
Another application of the plastic injection industry is the use in the packaging industry. Different types of goods are produced in the world, all of which need good packaging. Such materials include chemical and non-chemical products whose packaging must be made of a special polymer depending on the degree of compatibility of each. Medicines, detergents and food packaging are among the plastic products of this industry.

The use of plastic injection in the medical industry
If we take a deeper look at the performance of plastic injection in various industries, we find that one of the industries that benefit from plastic injection is the manufacturing of medical equipment. Almost all medical devices, from polymer prostheses to devices such as syringes, tubes, angiokets, are produced in the process of plastic injection and medical standards.

Application of plastic injection in construction industry
The application of plastic parts is not only in the manufacture of airplane and car parts, but in other industries such as construction, parts that have high strength and long life are needed. Polymers used in the injection method for construction materials and accessories include PVC, heavy polyethylene, polystyrene, acrylic and polyethylene. Insulators, water tanks, sewer pipes and electrical wiring are made in this way.

Application in the communication industry
Plastic injection has many applications in the field of communication. Most of the devices that are used for telephone communication and Internet connection are made in plastic injection operations. Even the wires and covers of telephone lines are made using the injection method of polymers in a special mold.
