From First Order to a Broader Fabrication Workshop: Indonesian Customer Expands with Weissenberg

Project at a Glance

A Customer Relationship Built Through Repeat Use

This Indonesian project is different from a one-time machine delivery.

The cooperation began in 2025 and gradually expanded across several different thermoplastic fabrication processes. Earlier purchases included plastic welding tools, followed by large-format sheet butt welding equipment and later CNC routing equipment.

As new production requirements developed, the customer continued adding equipment for different stages of the fabrication workflow rather than purchasing an entire workshop configuration at one time.

This gradual expansion is important because the later orders followed real workshop experience with previously supplied equipment.

Stage 1: Large-Format Sheet Welding with WeiBond 3000

One of the key machines added to the workshop was the WeiBond 3000 plastic sheet butt welder .

With a maximum working width of 3,000 mm, the WeiBond 3000 provides a dedicated platform for large-format thermoplastic sheet joining. For PE, PP and PVDF sheet, the machine is specified for welding thicknesses from 3 to 40 mm.

This gave the customer's workshop a controlled process for long sheet butt welds, while handheld extrusion and hot-air tools remained available for detail work and other fabrication tasks.

Stage 2: Expanding into CNC Sheet Preparation

The next major addition was CNC routing equipment for cutting, trimming and preparing thermoplastic sheet components.

Accurate sheet preparation is closely connected with the fabrication process. Before welding or forming, the sheet dimensions and mating edges need to match the intended component geometry.

Adding CNC routing therefore expanded the workshop beyond welding alone. It gave the customer another controlled process for preparing plastic components before subsequent forming, assembly and welding operations.

Stage 3: Extrusion Welding, Hot-Air Tools and Weldy Accessories

Large-format sheet butt welding is only one part of a thermoplastic fabrication workflow.

Fabricated components may also contain corners, attachments, reinforcements, local joints and other areas where a large sheet butt welding machine is not the appropriate tool.

The customer therefore continued purchasing extrusion welding equipment, hot air guns and various Weldy accessories for these additional workshop tasks.

These tools complement the larger machines rather than replacing them. The sheet butt welder handles suitable long sheet seams, while extrusion welding and hot-air tools provide flexibility for localized fabrication and assembly work.

Latest Requirement: Ø250 mm Ventilation Duct Fabrication

In October 2026, the customer returned with another production requirement: fabricating thermoplastic ventilation duct sections with a diameter of approximately 250 mm.

Although the workshop already operates a 3-meter WeiBond 3000 for larger sheet work, the new application involved significantly smaller components.

The customer therefore selected a WeiBond 1500M Manual Plastic Sheet Butt Welder as a more appropriately scaled machine for this type of fabrication.

This illustrates an important equipment-selection principle: the largest machine is not automatically the best machine for every fabrication task.

Component dimensions, handling requirements, working width and intended geometry all need to be considered when selecting a plastic sheet welding machine.

Factory Test for the Customer's Ø250 mm Duct Requirement

Because the latest project involved a specific small-diameter duct requirement, Weissenberg carried out a forming test before delivery.

The test demonstrated an approximately Ø250 mm rolled diameter, providing a direct check against the customer's intended ventilation duct application.

This type of application test is useful when machine selection depends not only on general specifications, but also on the geometry of the finished component.

Why Add a WeiBond 1500M When the Workshop Already Has a WeiBond 3000?

At first glance, adding another sheet butt welder may appear to duplicate equipment. In practice, the WeiBond 3000 and WeiBond 1500M serve different workpiece scales and workshop requirements.

The comparison shows why machine selection should not be based only on maximum working width. A workshop producing components of very different sizes may benefit from using different machines for large-format and small-format work.

How the Equipment Supports Thermoplastic Ventilation Duct Fabrication

Thermoplastic ventilation and exhaust duct production can involve several complementary fabrication processes.

One Customer, Multiple Thermoplastic Fabrication Processes

Looking at the customer's purchases together provides a clearer picture than viewing each order separately.

The workshop has gradually developed capabilities covering:

• large-format plastic sheet butt welding;
• small-format sheet butt welding;
• CNC sheet cutting and preparation;
• extrusion welding;
• hot-air fabrication;
• Weldy tools and accessories.

Each new purchase has addressed a different part of the fabrication process as the customer's production requirements have expanded.

What the Repeat Orders Show

The most important part of this case is not simply the number of machines purchased.

Since the first cooperation in 2025, the customer has continued adding equipment across multiple product categories after gaining practical experience with the previously supplied machines and tools.

The purchasing pattern has developed from welding tools into large-format sheet welding, CNC preparation, detail welding, hot-air equipment and now a dedicated WeiBond 1500M for smaller ventilation duct components.

This reflects a workshop that is developing its fabrication capability step by step, matching new equipment to actual production requirements as they emerge.
