Plastic Extrusion Welding - Process, applications, benefits & more

Exploring Extrusion Welding: A Definitive Guide

Introduction: In the realm of plastic fabrication and joining, extrusion welding emerges as a pivotal technique that stands at the intersection of innovation and functionality.

This comprehensive guide delves into the intricacies of extrusion welding, shedding light on its process, applications, benefits, and the transformative impact it has across industries.

Understanding Extrusion Welding: Extrusion welding, a thermoplastic welding method, is a process where two plastic components are fused together using heat and pressure.

The technique employs a heated welding gun equipped with a nozzle to simultaneously melt the surfaces being joined and a plastic filler material, often in the form of a welding rod.

As the molten filler material is pushed into the joint, it forms a homogenous and robust connection upon cooling and solidification.
