Customized WeiBond 4000 & ATLA1200 CNC for an Icelandic Thermoplastic Manufacturer

The WeiBond 4000 was configured with a 4000 mm working width, 90° vertical butt welding and a movable beam, while the ATLA1200 CNC added dedicated capability for fabricating large-diameter thermoplastic fittings up to 1200 mm.

Rather than purchasing two unrelated machines, the customer was strengthening two connected areas of production: large-format sheet fabrication and large-diameter pipe fitting fabrication.

Project Overview

The Requirement: Expand More Than One Fabrication Capability

The customer's requirement extended beyond purchasing a standard plastic sheet welding machine.

On the sheet fabrication side, the workshop needed a large-format platform capable of handling 4-meter thermoplastic sheets.

Flat welding alone was not enough. The machine also needed to support 90° right-angle welding and provide more flexible access when loading, positioning and removing large workpieces.

At the same time, the customer wanted to increase its ability to manufacture large-diameter fabricated thermoplastic fittings in-house.

Two Machines, Two Complementary Production Processes

Large thermoplastic fabrication projects rarely consist of only flat sheet or only straight pipe.

Different components require different fabrication methods, which is why the two machines were selected to address separate but connected parts of the production workflow.

WeiBond 4000: Customized Beyond Standard Flat Welding

The WeiBond 4000 Plastic Sheet Butt Welder provides a maximum working width of 4000 mm, giving the customer the capacity to join large thermoplastic sheets on one platform.

For this Iceland project, however, standard flat welding was only one part of the required workflow.

The machine was customized with:

• • 90° vertical welding capability for suitable right-angle sheet structures
• • A movable beam to increase access and flexibility around large workpieces

Why 90° Vertical Welding Was Added

A standard sheet butt welding machine joins two thermoplastic sheets on the same plane.

This is ideal for producing larger continuous panels, but large fabricated structures may also require long right-angle joints.

The additional 90° welding configuration allows suitable sheets to be positioned at approximately 90 degrees during the heated-tool welding cycle.

This gives the workshop another controlled method for producing suitable long, straight structural seams.

Extrusion welding can still be used for complex geometries, reinforcement and detail work. The vertical butt welding configuration therefore complements rather than replaces other fabrication methods.

Why the Movable Beam Matters

Large-format plastic fabrication creates a challenge that is sometimes overlooked during machine selection: workpiece access.

As sheet dimensions and partially assembled components become larger, operators need enough space to:

• • Load large thermoplastic sheets
• • Position bulky workpieces
• • Reposition partially fabricated structures
• • Prepare parts for flat or vertical welding
• • Remove completed components from the welding area

A permanently fixed machine structure can restrict access during some fabrication sequences.

The movable beam configuration provides greater flexibility around the working area, helping the workshop adapt the machine to different sheet sizes and component geometries.

ATLA1200 CNC: Expanding Large-Diameter Fitting Fabrication

The second machine supplied as part of the project was the ATLA1200 CNC Fitting Fabrication Machine.

While the WeiBond 4000 works with flat thermoplastic sheets, the ATLA1200 CNC addresses the pipe side of the customer's production.

Its working range covers 630–1200 mm (24" IPS–48" IPS), allowing the workshop to fabricate large-diameter thermoplastic fittings from pipe sections.

Depending on the fitting configuration, the machine can be used to produce:

• • Elbows/bends
• • Tees
• • Crosses
• • Wyes

This gives the workshop additional in-house capability for producing customized fittings rather than relying only on straight pipe or externally sourced fabricated components.

Why the WeiBond 4000 and ATLA1200 CNC Work Well Together

The value of this project becomes clearer when the two machines are considered together.

Industrial thermoplastic fabrication may involve:

• • Large welded sheet panels
• • Right-angle sheet structures
• • Large pipe elbows
• • Tees and branches
• • Cross fittings
• • Wyes
• • Other customized thermoplastic assemblies

The WeiBond 4000 addresses the sheet-fabrication side of this workflow.

The ATLA1200 CNC addresses the large-diameter pipe-fitting side.

Together, they give the workshop a broader in-house fabrication range than either machine could provide alone.

Production Requirement vs. Selected Solution

A Broader Approach to Thermoplastic Equipment Selection

This Iceland project illustrates why fabrication equipment should be selected around the complete production process, rather than treating every machine as an isolated purchase.

If the customer's requirement had involved only large flat sheets, a conventional 4-meter butt welding machine could have been sufficient.

Once right-angle structures, workpiece access and large-diameter fabricated fittings were considered, the project required a broader combination of equipment.

What Makes This Project Different?

1. It Was a Combined Capacity-Expansion Project

The investment covered both sheet-based fabrication and large-diameter pipe fitting fabrication.

2. The Sheet Welder Was Customized Around Product Geometry

The addition of 90° welding means the WeiBond 4000 was intended for more than flat panel production.

3. Workpiece Handling Influenced Machine Design

The movable beam reflects the practical reality that access and positioning become increasingly important as thermoplastic components grow larger.

4. Fitting Fabrication Extended to 1200 mm

The ATLA1200 CNC added dedicated capacity for fabricated thermoplastic fittings across the 630–1200 mm range.

Key Takeaways

• • Large-format fabrication requires more than working width.
  Product geometry, workpiece access and welding orientation can all influence machine configuration.
• • 90° welding expands the role of a sheet butt welder.
  The same platform can support both flat panels and suitable right-angle structures.
• • A movable beam can improve flexibility around large workpieces.
  Material handling becomes increasingly important as component size and complexity increase.
• • ATLA1200 CNC extends in-house fitting capability to 1200 mm.
  Large elbows, tees, crosses and wyes can be fabricated on a dedicated production platform.
• • Sheet fabrication and pipe fitting fabrication are complementary.
  Combining both capabilities gives a thermoplastic workshop greater flexibility when producing complex industrial systems.
