Weissenberg Welder is an official distributor of Weldy plastic welding equipment, offering high-performance hot air guns, extrusion welders, and accessories. With over 19 years of experience, we provide original Weldy products, technical support, and after-sales service for efficient plastic welding in fabrication, civil engineering, and waterproofing projects.

In 2025, plastic pipe welding becomes faster, smarter, and more eco-friendly. Weissenberg's Riyang series supports various materials with automated and precise welding. Their machines are used worldwide in water, chemical, and municipal projects, providing reliable, leak-free welding solutions.

Since 2006, Weissenberg has been providing high-quality plastic sheet butt welding machines widely used in chemical processing, water treatment, construction, and other industries. Our products meet international standards and have been exported to over 30 countries, earning strong customer trust.

Weissenberg is the official distributor of Weldy extrusion welders, offering genuine models like Booster EX2, EX3, HT1600, and HT3400 for reliable HDPE and thermoplastic welding.

Weissenbergwelder, a global leader in plastic welding technology since 2006, explains how plastic sheet butt welding machines create strong, seamless joints for HDPE, PP, PVC, and more—without adhesives. Explore the process, supported materials, and industrial applications, and discover why Weissenberg's CE-certified, DVS-compliant solutions are trusted in over 30 countries.

Weissenberg delivered an RPH1500M welding machine to a French customer. The initial welds were poor. We quickly analyzed the issue and adjusted key settings like heating time, bead-up, cooling time, and pressure following the DVS 2207 standard. After these changes, weld quality improved greatly. This shows Weissenberg’s strong support and commitment. We will keep improving to provide better welding solutions.

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.

Weissenberg explores the DVS 2207 standard and how precise control of temperature, pressure, and heating time improves plastic welding quality. Covering PE, PP, PVC, and PVDF, the article shows real-world results with Weissenberg’s smart welding machines. Learn how PID control and PLC automation boost consistency, efficiency, and performance in industries like chemicals, construction, and new energy.

Discover Weissenberg's high-performance plastic sheet welding machines designed for PP, PE, PVC, and PVDF materials. With 19 years of expertise, we offer DVS 2207-11 compliant butt welders featuring synchronous drive, intelligent Mitsubishi PLC control, and precise temperature regulation for durable, high-strength welds in industrial applications.

An Australian customer faced low efficiency in making wastewater tank covers due to manual processes. To solve this, Weissenberg provided a customized solution by adjusting the machine's beam height to 80mm and designing a new press plate for precise dimensions. The upgrade enabled automation, improved productivity, and ensured consistency. This project reflects Weissenberg’s focus on customer needs and its strength in tailored, efficient sheet processing solutions.
