Precision hot-wedge welding for large-scale industrial production
The Forsstrom HW-WT travelling hot-wedge welding machine is engineered for manufacturers who require consistent weld quality, high production speed, and low operating costs. Designed for demanding industrial environments, HW-WT delivers precise, repeatable seams across PVC, TPU, PU, and PE foils—whether welding thin films or multilayer technical textiles.
With Siemens servo technology, digital roller control, and an intelligent Route Mode, HW-WT ensures stable welding performance on straight runs, curves, and complex shapes. Its travelling design and long welding table make it ideal for joining large and heavy panels with accuracy and efficiency.
Why choose the Forsstrom HW-WT?
Consistent quality at high speed
HW-WT welds at speeds of up to 30 m/min while maintaining uniform seam quality. Servo-controlled foil fusion and precise pressure control ensure reliable results across varying material thicknesses.
Energy-efficient and cost-effective
Compared to hot-air welding systems, HW-WT consumes up to 92% less energy and 99.5% less compressed air. This reduces operating costs, lowers noise levels, and minimizes fumes in the production environment.
Intelligent control for complex welding
Route Mode automatically adapts speed and drive when welding curves and complex geometries. This reduces operator dependency and improves repeatability in demanding applications.
Typical applications
The HW-WT Travelling Hot-Wedge welder is well suited for:
Awnings and sun protection systems
Billboards and signs
Sports and leisure products
Inflatable structures
Tarpaulins and truck covers
Tents and lightweight structures
Software and control system
The 10.1” HMI multi-touch interface provides:
-
Real-time monitoring of welding parameters
-
Parameter memory for repeatable production
-
Intuitive navigation for fast setup and operation
Built on proven Siemens components, the control system ensures long-term reliability, low maintenance requirements, and consistent weld quality over time.
Available options
