Industry Information

Advances in Plastic Extrusions

There have been various positive signs for the growing economy. Plastic solutions are among the materials that are used in a large spectrum of industries and applications. When the demands for these products increase it is an indicator that other industries may also have increasing demands. Plastic solutions are more widely accepted as a viable and trustworthy component compared to their counterparts such as metal or wood. There are numerous benefits when utilizing plastic products. Plastic extrusion products have been proven as a vital material for the medical and clean room industries. These industries require sterility and the surface of plastic items are ideal for maintaining high levels of cleanliness. The uniform molecule structure is also a significant advantage. The medical industry, for example, benefits from this structure because many medical applications require tubing and through the plastic extrusion process manufacturers can achieved the desired specifications of those applications.

To meet the higher demands many manufacturers have been upgrading facilities in recent months which allows for faster and larger volumes of plastic extrusions but also more accuracy when cutting the plastic items. Sophisticated products are equipped with more intricate parts so manufacturers must have the capabilities to adhere to exact specifications even down to the smallest measurements. These newer processes have very interesting attributes and even though the products are being manufactured at a faster pace the integrity of the structures are not being compromised. Manufacturers will work with customers to create affordable solutions that adhere to sterility and dimension requirements.

Plastic Extrusions

Plastic extrusions are plastic shapes produced by forcing molten plastic through a die. Plastic extrusion is a continuous process that produces long plastic profiles; plastic strips, plastic channels, plastic trim and other basic plastic shapes are all produced by plastic extruders. Plastic extrusions play an important roll across industry, commerce and in consumer markets.

Automotive manufacturers employ extruded plastics as engine components and as decorative and functional trim on auto exteriors. PVC extrusions, particularly PVC tubes, are used extensively in plumbing systems and in wastewater treatment operations. Chemical processing operations also make use of extruded plastic tubing, and because different plastics feature different qualities of reactivity when exposed to chemicals, plastic materials are chosen for their applications based on such qualities. Acrylic extrusions, for example, are characterized by their optical clarity and durability. They are, for these reasons, often well suited to use as tubing in chemical processing, because their contents can be easily visible when inspected by workers. Some unique applications call for an extrusion that features the qualities of more than one material. In these cases, coextrusion can be used to mix two plastics together, allowing for the qualities of two plastic materials to be present in one product.

The term polymer extrusion is sometimes used interchangeably with plastic extrusion. This is not incorrect, though it is not the most precise way to describe the process. Technically, a polymer is a large molecule made up of many similar monomers, which are small molecules. Biopolymers like proteins and nucleic acids are essential for life. These are not the kinds of polymers to which the words "polymer extrusion" refer. When the words "polymer" and "extrusion" are paired together, they refer only to plastics and elastomers (natural rubber is an example of an elastomer). In the case of plastic extrusion, a very long list of plastic materials is at the disposal of companies that provide plastic fabrication services. High density polyethylene (HDPE), low density polyethylene (LDPE), PETG, PVC, butyrate, vinyl, polypropylene, and polystyrene are just a few of the most commonly extruded thermoplastics. A thermoplastic is a plastic material that, when exposed to sufficient heat, becomes plasticized. A plasticized thermoplastic can be shaped into useful products and retain the shape once cooled. Thermoplastics are highly valued for this quality, and they are also valued because they can be recycled at the end of their lifespans and reshaped by the same process.

The plastic extrusion process is very standardized, and there are few deviations between extrusion operations in terms of the basic principles of extrusion. Operating temperatures and output speeds may vary depending on the properties of the plastic material, but plastic extrusion processes resemble each other very closely aside from these differences. The extrusion process begins with a collection of raw plastic materials in a hopper suspended above a conveyance channel. When a panel at the bottom of the hopper is removed or retracts, gravity directs the plastic into the channel. Inside the channel is a long shearing screw that forces the plastic down the channel as it turns. The friction caused by the turning of the screw causes the plastic to become molten. Some extruders feature supplementing electrical heating elements to aid in the melting of the plastic. By the time the plastic reaches the end of the channel, it is ready to be shaped. At the end of the channel is a die, which is a specially-designed tool used to form raw materials into usable products. In the case of plastic extrusion, a die is a metal plate cut with a hole through which the plastic is forced.

When the molten plastic reaches the die, it is forced through, taking its shape as a result. The plastic emerges on the other side of the die as newly extruded plastic material. The plastic is quickly cooled, which causes it to harden and keep its shape. The extrusion can then be cut and prepared for shipment or sent for additional processing like labeling, painting, anti-static treating or other surface treatment. The shape of an extrusion die determines the shape of the extrusion. Every die is different; they are specially designed to accommodate individual processes. The simplest possible die designs are nothing more than simple shapes. A circle-shaped die would produce a plastic rod, while a square-shaped die would produce a continuous plastic square. Extrusions like pipes require dies fitted with special pins that allow hollow places to form. Textured plastic sheets like floor mats can also sometimes be produced by extruders. Plastic sheet dies would be flat with grooves to create the texture. The coextrusion process, in which two or more plastic materials are combined in a single extrusion, features one die connected to a forked conveyance channel into which the different materials are directed and mixed together. The number of possible extruded plastic shapes is limited only by the imaginations of their designers.
