The Process of Plastic Extrusion

The Process of Plastic Extrusion

The process of plastic extrusion at Keller Plastics involves the heating of polymeric compounds to the point of melting, at which point they are pressed through a die that is attached to the front of the extruder. Plastic extrusions can be made into many shapes. A conveyance system at the end of the line allows the profile to be boxed.

The specifications of an individual job request will determine the precise sort of compound added to a hopper that sits over the screw opening, which itself is at the back of the extruder system. The components such as the screw and the barrel in which it is contained are heated so that the polymer is melted gradually, while the materials are sent toward the head of the extruder via the screw.

Upon reaching the front portion of the extruder, the polymer material is pushed through a custom opening made to suit the product’s specifications. It may be in the form of a tube, rod, or an alternative profile. After the material leaves the front of the extrusion machine, the heated material is sent to a tool engineered to prepare it for shaping into the desired extruded plastic profiles. Tooling equipment then ensures that the material is the correct shape and size required by the customer’s specifications and meets their print.

Because extrusion of this sort involves the melting of polymers, the ultimate shape and size of the part being made will be influenced by the tooling being used, but also by the person operating the extruder. This person is responsible for regulating the melt conditions and also for the cooling process that occurs at later stages of the process.

Every extrusion line is equipped with a takeoff unit at the end so that tension is exerted on the material as it leaves the extruder. This plays a significant role in the speed of the extrusion line as well as the final plastic extrusion shape.

At the very end of the extrusion machinery, the parts will be cut to the designated length or put on spools.

Once the parts are finished by the professionals at Keller Plastics, they are placed in containers uniquely suited to the product type, where these can take the form of bundles, boxes, or bulk packaging. The final step in the process is when the completed extruded plastic profiles are shipped directly to the location designated by the customer. Keller Plastics can handle all aspects of shipping to the final site.
