High-precision hot-wedge welding for controlled industrial production
The Forsstrom HW-WS stationary hot-wedge welding machine is designed for manufacturers who require stable, repeatable weld quality in fixed production setups. Built for demanding industrial environments, HW-WS delivers precise seam control across PVC, TPU, PU, and PE foils, from thin films to multilayer technical textiles.
Powered by Siemens servo technology and advanced digital roller control, the HW-WS ensures consistent welding performance at speeds of up to 30 m/min. Its energy-efficient hot-wedge process reduces operating costs while maintaining a clean, low-noise working environment.
Why choose the Forsstrom HW-WS?
Stable, repeatable welding quality
The stationary configuration provides controlled and predictable welding conditions. Servo-controlled foil fusion and precise pressure regulation ensure uniform seams across long production runs.
Energy-efficient industrial welding
Compared to hot-air welding systems, the HW-WS consumes up to 92% less energy and 99.5% less compressed air, reducing total cost of ownership and improving workplace conditions.
Intelligent control for complex seams
Route Mode automatically adjusts speed and drive when welding curves or complex shapes, supporting consistent quality with reduced operator intervention.
Typical applications
The HW-WS Stationary 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
