Plastic Extrusions: Basic Principles and Processes

Plastic extrusions are a critical component of the plastic industry. Using the extrusion process, a manufacturing company can produce a high volume of finished parts and components. With so much versatility, a broad range of industries relies on the finished products.

Fundamentally, the goal with extruded plastic is to make parts and components based on what the customer needs. Melted plastic flows into a die, which determines the finished product’s size and shape. Customers end up with parts or components they use as part of their manufacturing processes or in the products they make for their customers.

The extruded product creation process consists of feeding plastic material into a barrel with rotating screws inside. With generated pressure and heat, the plastic melts. That material then feeds into a die, which shapes the part or component. Once the hot plastic cools, the molded product gets ejected.

In the case of custom plastic extrusions, the fabrication process involves a few more steps. For that, the fabricator can add color pigments, as well as other performance-enhancing additives to the plastic granules or pellets. For more complex shapes, a custom die replaces the standard one; the outcome is a uniquely or intricately shaped product, fabricated to meet specific customer requirements.
