Plastics Manufacturing

With the advancement of technology, a lot of new processes have come into place. Plastic extrusion is one of the methods which are commonly being used all over the world. It basically involves melting the raw plastic in order to form products in particular shape and size. A lot of plastic industries work over plastic extrusion products as it is the most feasible and versatile way to make commonly used plastic products such as wires, tapes, pipes, weather stripping, plastic sheets and lots more. Through this process, people can also save our planet because scrap plastics are one of the major cause of global warming and you can recycle these scrap plastics through the plastic extrusion process.

Explaining Plastic Extrusion Process

Basically, the raw plastic or also known as resins are put into an extruder barrel and then pressed with a hopper from the top.

During the process, different substances are dropped in the barrel such as UV inhibitors, colorants and more based on what the finishing product would be.

The raw plastic is melted and then new shapes are formed. The process of plastic extrusion is used in domestic as well as industrial purposes too. It is one of the best methods to use the scrap plastic goods for recycling and making new products. However, many countries are now using eco-friendly ways for plastic extrusion, to save the environment from pollution and global warming.

The Procedure of Making Plastic Extrusion Products:

There is a rotating screw inside the barrel, which gets heated and melts the raw plastic. Once the plastic is pressed, it is passed to the die stage where the shape of the specified product is given. The best thing about the process is any shape can be made, however one should make sure that the process is continuous otherwise it could lead to troubles with warping. It is one of the most crucial points which are to be remembered during the process of plastic extrusion products.

The final products of plastic cannot be put to use immediately after the shape is formed. They need to go through a bath which makes the product cool. It takes a long time for the plastics to get cooled as they are good thermal insulators. If you could not make the desired shape with the plastics then you can do some plastic extrusion process on the same and get your required plastic extrusion product shapes.

Types of Plastic Extrusion Procedures to Know

There are different kinds of plastic extrusion processes used in the industries. The procedure is selected based on what kind of final product is to be created.

Over-Jacketing: – If any plastic product needs a coating for protection purposes, then a method called over-jacketing is used. Another name for this procedure is wire coating.

Blown Film: – The regularly used plastic products are made using this process, including bags for storing food or other commodities. One of the common types of plastic polyurethane is used here.

Tubing Extrusion: – This method is similar to the basic plastic extrusion process, however, there are mandrels used to create the final plastic extrusion products.

Extrusion Coating: – It is basically an added stage of the main extrusion process. If the final product did not come as desired then this stage helps and a finished product comes through.

There are still many more procedures which are being tried and tested in the industries. This procedure offers immense help to the consumer market as it creates an increasing number of products.
