What is Extrusion Welding?

Extrusion welding is a method used for joining plastics such as PP and HDPE. This process was developed in the 1960s as an improvement upon hot gas welding with the hand extruder gun. It involves the manual work of a qualified welder, but can also be automated for continuous welding applications.

During extrusion welding, molten thermoplastic is shaped and extruded onto the parts being joined, creating a strong joint. This is accomplished using a plastic extruder gun with a welding head and a nozzle for hot air, along with an extruder that pushes out the filler material. The joining surfaces are then heated and joined with molten or plastic filler material.

Where can Extrusion Welding Be Used?

Extrusion welding can be used in a variety of applications, including:

Plastic fabrication: It is commonly used to join plastic sheets and components in the fabrication of tanks, containers, and other plastic structures.

Plastic pipe welding: Extrusion welding is used to join thermoplastic pipes in plumbing, industrial piping, and infrastructure projects.

Geomembrane installation: It is used in the installation and repair of geomembranes for environmental containment and lining systems.

Automotive and transportation: Extrusion welding can be used in the repair and fabrication of plastic components for vehicles and transport equipment.

Construction: It can be used in the construction industry for joining plastic sheets and components in various applications.

What Are Extruder Benefits?

Extruders offer several benefits in various industries, including:

Versatility: Extruders are capable of processing a wide range of materials, including plastics, metals, food products, and more.

Customization: They can produce a variety of shapes and sizes, making them ideal for manufacturing custom products.

Efficiency: Extruders are known for their high production rates and consistent output, leading to improved productivity and cost-effectiveness.

Control: They offer precise control over the shaping and forming of materials, leading to high-quality end products.

Automation: Extruders can be integrated into automated production lines, reducing the need for manual labor and increasing efficiency.

Sustainability: In some applications, extruders can contribute to sustainability efforts by enabling the use of recyclable materials and minimizing waste.
