What Is Plastic Extrusion? A Beginner’s Guide

Plastic extrusion is one of the most efficient and versatile manufacturing processes for creating continuous plastic profiles. At Lincoln Plastics, it’s the foundation of what we do — transforming raw materials into durable, custom-shaped components that support industries from agriculture to construction.

Whether you’re new to the process or just need a refresher, here’s a quick guide to understanding how plastic extrusion works and why it matters.

What Is Plastic Extrusion?

Plastic extrusion is the process of melting raw plastic pellets and forcing the material through a custom die to form a continuous shape — like tubing, channels, or profiles. Once shaped, the plastic is cooled, cut to length, and finished to meet exact specifications.

Think of it like squeezing toothpaste from a tube — the shape of the opening (die) determines the shape of what comes out. But in extrusion, precision and control are everything.

Why It’s Useful

The process offers unmatched consistency and scalability for parts that require:

• Uniform cross-sections (same shape along their length)
• Material flexibility — many types of thermoplastics can be used
• Cost efficiency for long runs of identical profiles
• Customization in color, wall thickness, and finish

Lincoln Plastics: Experts in Custom Extrusion

We specialize in custom runs — not mass production. Our team partners with OEMs to design and produce parts that fit your exact needs. From concept to delivery, we ensure every extrusion meets your application requirements.

Why It Matters to OEMs

Understanding extrusion helps engineers and purchasing teams make smarter sourcing decisions. When you know how your components are made, you can better balance performance, cost, and reliability.
