> How Ultrasonic Welding is Becoming the New Engine of Green Manufacturing？
As manufacturing pivots toward low-carbon transformation, ultrasonic welding—dubbed "green welding"—is quietly revolutionizing production lines. By eliminating traditional soldering materials and high energy consumption, it redefines the relationship between manufacturing and environmental protection.
Adhesive bonding: Relies on chemical agents, releasing VOC (Volatile Organic Compounds) emissions while increasing production costs and storage complexity.
Screw fastening: Requires additional drilling and metal parts, increasing material use, weight, and assembly time.
Hot melt welding: Energy-intensive, low thermal efficiency, with risks of smoke and odor emissions.
These conventional methods not only drive up long-term costs but also perpetuate environmental strain.
Energy efficiency: Completes bonds in 0.1–3 seconds, consuming only 30%–50% of the energy required by hot plate welding. A typical production line with 100,000 annual units can save ~150,000 kWh of electricity.

Near-zero emissions: No chemical adhesives used, eliminating VOC emissions and complying with stringent environmental standards.
Material savings: Requires no screws, glue, or auxiliary materials, reducing both cost and waste.
High-speed production: Rapid welding cycles significantly boost throughput and operational efficiency.
Ultrasonic welding uses high-frequency mechanical vibrations (typically 20–40 kHz) to generate frictional heat at the molecular level, achieving instantaneous melting and fusion. This process ensures not only eco-friendliness but also consistently high bond strength.
Domestication of high-end equipment:
While the global high-end ultrasonic plastic welding equipment and high-speed nonwoven ultrasonic welding equipment markets are predominantly dominated by a few international players such as Branson, Herrmann, and Dukane, SBT Ultrasonic Technology Co., Ltd. (SBT Ultrasonic, Stock Code: 688392) is actively expanding its presence and advancing the global expansion of high-end ultrasonic plastic and nonwoven welding solutions.
SBT Ultrasonic's self-developed equipment excels in energy consumption control while maintaining high welding precision and stability, offering companies a more cost-effective and sustainable manufacturing solution.
As environmental regulations tighten and carbon reduction becomes urgent, ultrasonic welding is emerging as a key enabler of sustainable manufacturing. From automotive and medical devices to consumer electronics and eco-packaging, this technology is demonstrating its environmental advantages across industries.
By 2025, ultrasonic welding is expected to see significantly broader adoption in plastic joining, solidifying its role as a cornerstone of green manufacturing.
