Welding extruder for PE-HD PP-H PP-C PVC-U and PVDF

Extrusion welding of polyolefins such as PE-HD, PP-H, PP-C or halogen-containing materials such as PVC-U and PVDF is possible without any problems thanks to the electronic control of the melt temperature and very precise patented temperature measurement directly at the screw tip in the melt.

Our welding extruders are available in output classes from 0.8 to 6 kg/h (PE-HD) and have actual and setpoint displays for the melt temperature as well as cold start protection.

The wire is pulled in using a patented internal wear- and maintenance-free pull-in system without external pull-in aids.

All our welding extruders are equipped with welding air preheating and are available with or without an air blower.

Devices with air blowers are particularly suitable for assembly work on the construction site.

Devices used in the landfill sector can also be supplied as granulate extruders , whereby granulate with a grain size of up to approx. 3 mm can be used.

Welding rods for extrusion welding are used exclusively as round rods with Ø3, Ø4 or Ø5 mm, depending on the device model and its welding capacity.

These “endless” welding rods on spools or in coils can be obtained from us in the highest quality and in accordance with the applicable DVS regulations.

We supply hand welding extruders in the following versions:

A welding extruder is a special type of extrusion machineused for the welding of plastics. plastics.

This machine enables plastic materials to be joined by heating and extruding, creating a strong weld seam.

Functional principle: A welding extruder uses the principle of plastic extrusion to join two plastic parts. The plastic material to be welded is fed into the extruder.

In the extrusion process, the material is melted by heating and then pressed through a nozzle.
The heated plastic strands fuse together and create a homogeneous weld.

Features of a welding extruder:

Temperature control:
Hand welding extruders have precise temperature control systems to ensure that the plastic material is heated to the required melting temperature.
Extrusion pressure:
The extruder generates a controlled pressure to press the molten plastic material through the nozzle, creating a uniform weld.
Nozzle selection:
Depending on the requirements of the application, different nozzle types can be used to achieve different welding geometries.
Versatility:
Hand welding extruders are versatile and can be adapted for various plastics and applications.

Applications:

Plastic welding:
Hand welding extruders are often used in plastics processing to weld parts such as pipes, profiles, containers or films together.
Repairs:
In the maintenance and repair of plastic parts, welding extruders are used to repair defective or damaged areas.
Construction:
In construction, welding extruders are used to create waterproof connections in geomembrane seals or PVC roofing membranes.
Automotive industry:
In the manufacture of plastic parts for vehicles, the welding extruder can be used to connect components.
Electrical industry:
Welding extruders can be used in the manufacture of electrical housings or components for a secure connection of plastic parts.

The use of a welding extruder provides a reliable and efficient method of joining plastic materials, which is widely used in various industries and applications.
