Product Name
Leister 146.649 Welding shoe complete (FWP-Int. Air) corner outsite 12mm
Brief Description
This Leister 146.649 welding shoe is a complete accessory designed for extrusion welding of plastics. It is specifically engineered for creating 12mm outside corner seams and features internal air guidance (FWP-Int. Air). This original Leister part ensures a precise fit and optimal performance when used with compatible Leister extrusion welders.
Popular Applications & Uses
- Plastic tank fabrication- Aquaculture construction and repair- Boat construction and repair- Welding of geomembranes and other plastic sheets in construction projects- Creating durable outside corner seams in various plastic structures and containers
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services- Marine- Pool/Spa/Plumbing- General Manufacturing- Cladding- Distributers & Resellers
Special and Unique Features
- Specifically designed for 12mm outside corner seams, ensuring precise and consistent weld geometry.- Features internal air guidance (FWP-Int. Air) for efficient and controlled heating during the welding process.- As an original Leister accessory, it guarantees high quality, durability, and a perfect fit with compatible Leister tools.- Compatible with several Leister extrusion welders, including WELDPLAST S2, FUSION 2, FUSION 3, and FUSION 3C.
Key Properties
- Type: Complete Welding Shoe- Seam Geometry: Corner outside seam- Size: 12mm (equivalent to approximately 0.47 inches)- Air Guide: Internal Air (IA)- Brand: Leister- Country of Origin: Switzerland- Material: Typically constructed from PTFE (Teflon) for its non-stick properties and resistance to high temperatures, common for plastic welding shoes.
Surface Compatibility
This welding shoe is primarily compatible with thermoplastic materials commonly used in extrusion welding, such as Polyethylene (PE) and Polypropylene (PP). These materials are frequently encountered in applications like tank building, geomembrane installation, and general plastic fabrication.
Known backups / known substitutes
- Other Leister welding shoes designed for different seam geometries (e.g., fillet weld, V-seam, overlap seam) or sizes.- Leister also offers blank welding shoes (e.g., 146.239) that can be custom-machined by the end-user for specialized applications.- Welding shoes from other plastic extrusion welder manufacturers like Munsch or Wegener, though these would typically require their respective brand's extruders or specific adapters.
Comparison Note
This Leister 146.649 welding shoe stands out due to its specialized design for 12mm outside corner seams with internal air guidance. While other welding shoes offer different geometries (e.g., fillet, V-seam) or external air guides, this particular model is optimized for precision and efficiency in specific outside corner applications. Its internal air guide ensures consistent heat distribution directly to the weld area, which is crucial for strong and uniform plastic welds.
