Plastic Extrusion Guide

Plastic extrusion is a highly customizable fabrication process that uses thermoplastic resins and a pre-shaped die to create components at high volumes. This manufacturing method can utilize different extrusion techniques based on the needs of the end application.

Plastic Extrusion Guide

Plastic extrusion is a highly customizable fabrication process that uses thermoplastic resins and a pre-shaped die to create components at high volumes. This manufacturing method can utilize different extrusion techniques based on the needs of the end application. This guide will discuss the process, advantages, materials, and final products of plastic extrusion.

What Is Plastic Extrusion?

Plastic extrusion is a manufacturing process that forms components by placing thermoplastic resin pellets in a closed cavity that melts and presses the resin through an opening in a die. The die features a predetermined shape, and the resin takes this shape. The extruded material sets as it cools.

Plastic extrusion is the most popular fabrication process for thermoplastic materials. Compared to other production techniques, plastic extrusion is more affordable, especially for large production runs. The process is particularly well-suited for creating components with a consistent cross-section, such as weatherstripping, wire insulation, and window and door frames.

Plastic Extrusion Products

Plastic extrusion is highly versatile and quickly produces parts that have a consistent profile. Some of the most common plastic extrusion products include:

Blinds

Blinds

The short length and consistent profile of blinds make them ideal for the extrusion process. Faux wood Venetian-style blinds are frequently produced using polystyrene.

Door profiles

Door profiles

Since door profiles feature a continuous profile, they are commonly produced using PVC extrusion.

Piping

Piping

The cylindrical profile of plastic piping or tubing makes it well-suited to the extrusion process. These products are produced using PVC or other types of thermoplastics.

Plastic sheeting

Plastic sheeting

Extrusion creates plastic sheeting for end-use in food and beverage products as well as recreational and industrial applications.

Wire insulation

Wire insulation

Many thermoplastics have good thermal stability and electrical insulation properties. Extruded profiles are commonly used to insulate cables and wires.

Weatherstripping

Weatherstripping

Weatherstripping product profiles are similar to window and door frames and are easily produced using the plastic extrusion process.

Window profiles

Window profiles

Because they feature a uniform length and profile, window profiles are commonly fabricated from extruded PVC.

Windshield wipers

Windshield wipers

The automotive industry relies on plastic extrusion technology to produce durable windshield wipers from a variety of synthetic rubbers.
