Fortiweld Manual Extruder and Field Equipment

The manual extruder group, covers equipment designed to carry out thermoplastic welding processes in the field in a portable and manually guided manner. This category brings together hand extruders used in a wide range of areas from geomembrane insulation applications to plastic tank and pool manufacturing, from wastewater structures to repair works in harsh terrain conditions, as well as geomembrane welding machines and pressurized air test devices that verify the reliability of weld seams. Fortiweld manual extruder products are selected to provide both durability and ease of use by focusing on the field needs of professional teams.

What Is a Manual Extruder and How Does It Work?

A manual extruder is a hand tool that operates on the principle of extrusion (filler) welding. The device melts the thermoplastic material in the form of welding rod or granules internally to a paste consistency and presses this melt between the surfaces to be joined, forming a strong, continuous weld seam. At the same time, a preheating channel blowing hot air prepares the surface of the main material to welding temperature; thus a homogeneous integration is achieved between the molten filler material and the base material. Hand extruders are particularly preferred in welding thick sheets, corner joints and parts with complex geometries when a stronger, filler-rich seam is desired compared to the hot air method.

Geomembrane welding machines, on the other hand, generally operate on the automatic or semi-automatic dual seam (hot wedge) principle; they bring two membrane layers on top of each other and join them under controlled heat and pressure, leaving a test channel between them. The pressurized air test device measures the tightness of the seam by pressurizing this test channel, thus verifying the quality of the weld non-destructively.

Where Is It Used?

• Sealing applications made with geomembrane: storage ponds, waste sites, treatment pools and irrigation structures.
• Manufacture and repair of HDPE and PP based tanks, reservoirs, chimneys and fabricated parts.
• Industrial coating and lining works requiring chemical resistance.
• Welding operations requiring repair, addition and revision in the field.

Product Variety and the Right Choice

There are three basic pieces of equipment under this category. Hand Extruder, offers the strongest solution for thick-section and angled joints requiring filler welding; it can be adapted from fine work to heavy manufacturing with different capacity and flow rate options. Geomembrane Welding Machine, is ideal for the fast and even joining of wide-surface membrane layers and provides efficiency on long seam lines. Pressurized Air Test Device is indispensable for the quality control of completed seams and provides tightness assurance before delivery.

The right equipment selection should be made according to the type of work, material thickness, working volume and field conditions. In projects with intensive and continuous welding, high-capacity models stand out, while in narrow areas and precision work, more compact and lightweight models come to the fore. For details such as the welding rod diameter, nozzle type and temperature range suitable for the project, we recommend reviewing the descriptions on the product pages or getting support from our technical team.

Usage and Assembly Tips

• Before welding, clean the surfaces to be joined of dust, moisture, oil and dirt; a clean surface is the prerequisite for a strong seam.
• Wait until the device reaches operating temperature and select the temperature setting appropriate for the material type.
• Before starting the actual work, always verify the settings by performing a test weld.
• Maintain a constant welding speed to achieve a homogeneous and continuous seam; avoid sudden stops and accelerations.
• At the end of the job, clean the nozzle and the melting channel; regular maintenance extends the device's lifespan.
• In critical applications, verify the seam tightness by inspecting it with a pressurized air test device.
