FRIMO INFRARED WELDING MACHINES
The strongest bonds for large plastic parts with 3D weld contours
Thermoplastics can be welded together using INFRARED radiation. Some of the radiation in infrared welding is absorbed by the material and transformed into heat. As a result, the surface layer is melted and the plastic components can be joined by being pressed together. Infrared heat is transferred without contact. The heat input is fast, specific and energy-efficient.
Power-controlled and time-controlled INFRARED emitters allow for precise and controlled welding processes. Typical applications are instrument panels, door trims and center consoles with complex, 2D or 3D welding contours. Particle-free welding is particularly used for joining air-duct pipes, fluid containers, tank systems and filters or filter housings.
INFRARED WELDING PROCESS
Customized to suit your needs
The following quality and efficiency factors of joined plastics vary, depending on the final product and application:
- Particle purity, such as for air or oil duct components (increasingly strict OEM regulations and norms)
- Use of reinforced, high-performance plastics, such as fiberglass reinforced plastics in lightweight and structural components
- Higher yield strength in security-relevant areas
- 100 % gas-tight
- Weldability of different materials
- Design freedom, including welding complex, 3D-geometries
- Productivity, economic viability and energy efficiency
- And much more!

- Emitters must be close to material
INFRARED WELDING CONTROLS
Controls, monitoring, and documentation for your IR machine
Various part contours and materials produce numerous parameters in the electrical controls system. We offer sophisticated, intuitive controls technology for reliable, high-quality processing of both small and large welding zones, various materials and material strengths, visible edges, and controlling overlapping emitters.
Operation and parameter entry are completed on a comfortable TouchPanel, integrated into either the operating panel or controls cabinet, depending on the machine's layout.
The following monitors are installed in our machines:
- IR emitter power monitor
- Freely adjustable power and delayed power for every control loop
- Welding path and pressure monitor
- Welding depth monitored by automatic registration of material height
- Heat input into welding seam can be recorded with INFRARED cameras and evaluated with image comparison
- Scanning though infrared cameras
