Waterstop Profile Extrusion Line for Infrastructure Sealing Project in North Macedonia

North Macedonia

Construction Material Supplier (Hydraulic & Underground Engineering Sector)

The customer is a construction material supplier based in North Macedonia, focusing on PVC-based products for infrastructure and underground engineering applications.

With increasing demand for reliable waterproofing systems in tunnels, underground structures, and municipal construction projects, the company planned to introduce a dedicated PVC waterstop profile extrusion production line to expand its product portfolio.

After technical discussions regarding profile geometry, sealing performance requirements, and continuous production stability, LangBo proposed a customized extrusion solution suitable for complex waterstop profile manufacturing.

The production line operates with stable extrusion performance and produces PVC waterstop profiles with consistent geometry and reliable sealing structure.

Even during long production cycles, the system maintains stable melt flow and uniform profile forming. The equipment is easy to operate, and the installation support from LangBo helped the customer quickly start production.

The final products are used in local infrastructure sealing projects, where dimensional accuracy and waterproof performance are critical.

• Designed for PVC waterstop profile extrusion in infrastructure sealing applications
• Stable profile forming with complex cross-section structures
• Reliable vacuum calibration and cooling system
• Continuous industrial production capability
• Suitable for tunnel, dam, and underground construction sealing
• Optimized for flexible PVC material processing

The extrusion system is configured with a conical twin screw extruder optimized for flexible PVC waterstop compounds.

The screw design ensures stable plasticization and uniform melt flow, supporting complex profile geometry required in sealing applications.

The waterstop profile die is customized according to the customer’s structural requirements.

It ensures accurate cross-section forming and stable output, suitable for various sealing profile designs used in construction joints.

A vacuum calibration and multi-stage cooling system is integrated to maintain dimensional stability.

The system ensures consistent profile shape during continuous extrusion, especially for long production cycles.

The haul-off system provides synchronized traction with stable pulling force, ensuring smooth profile movement without deformation during processing.

The cutting unit ensures precise length control for finished waterstop profiles, supporting downstream packaging and application in construction projects.

The PVC waterstop profile extrusion system in this case belongs to LangBo’s profile extrusion equipment series.
