This article compares plastic welding and adhesive bonding, covering performance and applications. Welding offers 80%-100% strength for similar plastics, while adhesives suit dissimilar materials with 30%-50% strength. New trends include laser-assisted bonding and nano-adhesives. Weissenberg machines provide precise, durable welding solutions for industries like plating tanks and spray towers.

Welding same-thickness PE and PP plates is challenging due to melting point and chemical differences. Weissenberg’s welding machines use hot-plate and extrusion methods with precise control. Using compatibilizers, copolymer layers, surface treatments, and optimized settings, reliable PE-to-PP welds are possible for non-critical applications, improving joint strength despite material differences.

Extrusion welding machines are crucial for production efficiency and weld quality, with output ranging from 1.5 to 3.6 kg/h depending on filler wire diameter. Key factors include wire size, material properties, temperature control, and feed system. Advanced machines feature dynamic output adjustments for optimal welding. Weissenberg’s welders offer precision, stability, and durability, supporting various materials with innovative technology trusted globally.

This paper explores the technical superiority of butt fusion technology in joining HDPE potable water pipelines (DN63–DN1200). Case studies and data highlight how precise control of fusion temperature, pressure, and time improves weld strength, leak prevention, and hygiene, making it the top choice for modern water systems.

This guide compares hot air welding guns, extrusion welders, and hot plate welding machines—three core technologies in plastic welding. Learn their principles, strengths, limitations, and how to choose the right tool for repairs, industrial waterproofing, or precision manufacturing.
