  • A Short History and A Long Future

    The plastic extrusion process is still a fairly recent one. First used in 1935, it has come a long way. It can now be used for creating rods, channels, profiles, sheets, trip and tubing. These products can be found in nearly every industry ranging from consumer manufacturing to automotive part fabrication. Already they can be made out of several different types of plastic and can be formed to nearly any length. While plastics in general have been around for awhile, they have only recently become extremely popular. Now we find...

  • Plastic Extruders and Even More Toys

    It never ceases to amaze me just how many toys my nieces and nephew have. I would put plastic pieces up there in the thousands. Every box today comes with at least ten small plastic pieces, and considering how on each birthday they seem to get a large truck full lets just say it is indeed a lot. While plastic toys can be made in countless ways, one method of creating certain pieces is through using plastic extruders. However, this method is more commonly known for its production of plastic...

  • Custom Plastic Shapes

    Any item can easily be made out of plastic, it just simply needs a mold and millions of the same item can be produced over and over again. Long continuous plastic pieces are made from the process of plastic extrusion which is heating material and pushing it through a die to make shapes. This process is used to make items like tubing, rods, hoses, trim and other continuous products. Plastic is a pretty cool material as it is relatively strong, durable and not easily breakable if dropped. Now of course...

Industry Information

Repeatable Memory Polymers

There has been an amazing discovery in the plastic industry. Researchers have discovered a polymer that is able to change shape automatically and repetitively. The shape shifting is prompted by the temperature and when the material reaches a pre-determined temperature then the plastic will shift into the new position. Once the plastic cools it reverts back to the original form. This new innovation, known as a “polymer actuator”, has the potential to be utilized in a wide range of industries. One of the main advantages of this new polymer design is the fact that it requires no outside electricity to create a linear motion.

Another interesting innovation in the plastic industry is hand moldable plastic. This plastic has a very low melting point and can easily be formed into any desired shape. This product is ideal in situations where a handcrafted plastic solution is necessary perhaps for an attachment or component replacement. The process to utilize this innovation is simple; heat the plastic between 136°F - 140°F and then it is ready to be molded. A big advantage with this type of plastic is it can be reformed an infinite number of times. This moldable plastic is ideal for prototyping, quick fixes and unique design.

These two advances in the plastic industry are only examples of the innovation potential from the industry. The repeatability and usability of these products are key factors to their success. Certain applications that require linear motion could greatly benefit from the self sustaining feature of the polymer actuator. Further manipulation of these materials on the molecular level will expose a plethora of discoveries that can be beneficial for consumers as well as manufacturers.

Plastic Shapes

Plastic shapes are specially-formed plastic objects that have been processed by a plastic shaping process. There are many plastic shaping processes, and they include molding, extrusion, casting and other methods. Each method is intended to create a different kind of plastic shape. Molding, for example, is the process best suited for the creation of complex, discrete products. Examples of discrete products include fasteners, pallets and cases for small electronics. Extrusion, on the other hand, allows for the creation of complex, continuous products. Examples of continuous products are trim, hoses and tubes.

Industry and commerce require broad access to discrete plastic shapes as well as plastic shapes produced by continuous manufacturing processes like extrusion. Extruded plastic products like PVC pipes, plastic hoses, plastic tubes, trim, channels and coextrusions are used extensively in all kinds of applications. Plumbing, gardening, chemical processing, building construction and furnishing depend heavily on extruded plastics. A wide variety of plastic materials can be extruded including high and low density polyethylene, butyrate, vinyl, polypropylene, polystyrene and acrylic materials. The extrusion process involves heating and pressurizing these raw materials and then shaping them with a die into usable products.

The plastic extrusion process takes place in a few steps. First, the raw thermoplastic material, in flake or pellet form, is poured into a hopper. From there it is fed down into a conveyance channel where it is heated by the turning of a large shearing screw. The friction caused by the turning of the screw combined with heat from electric heating elements causes the plastic to become molten by the time it reaches the end of the channel. At the end of the channel is a die, which is a tool used to shape raw materials into useful products. In the case of plastic extrusion, the die is a specially-cut shape in a metal plate through which the molten plastic passes. Once the plastic has become molten, it is forced through the die and emerges on the other side as a newly extruded plastic shape. Once extruded, the shape is allowed to cool and harden. It can then be cut to the appropriate length and either sent for shipment or prepared for additional processing like painting or labeling.
