Shaoxing Sweld Electric Co., Ltd. was established in 2018, located in Shengzhou, Shaoxing, China, the hometown of Shaoxing Opera. Covers an area of 3000 square meters, has a professional technical team and sales elite, a total of more than 50.                                                             The factory mainly produces exothermic welding powder and a complete set of products, including Ground rods, Ground wire, Stranded Wire, all kinds of electrical hardware connection parts, and lightning rod products. We have an annual production capacity of 500 tons of exothermic welding powder, providing various packaging solutions. Equipped with 7 high-speed CNC machining centers, with a daily production capacity of 180 sets of exothermic welding molds, it can provide customers with real-time design and manufacturing molding.                                 Sweld has passed ISO9001 quality management system certification, ISO14001 environmental management system certification, and ISO45001 occupational health and safety management system certification. And we also provide exothermic welding powder export special dangerous package certificate, exothermic welding molds export license, all kinds of products have passed the national certification laboratory product testing certification.                            

Recently, as safety requirements for global power and communications infrastructure continue to rise, exothermic welding molds, a core component of exothermic welding technology, have become a key focus of industry technological upgrades due to their exceptional performance and reliability. Combining precision design with high-temperature material science, these molds provide permanent, high-strength, molecular-level welds for conductors. They are widely used in lightning protection and grounding, power transmission, rail transit, and data centers. Made from high-density graphite, the exothermic welding molds offer excellent high-temperature resistance and thermal stability, withstanding temperatures exceeding 1600°C for thermite reactions, ensuring precise and consistent weld formation every time. Their internal cavity is scientifically designed based on conductor type and connection method, perfectly guiding the flow of molten metal to form a porous, fully encapsulated, highly conductive joint, eliminating the risk of loosening, corrosion, or increased resistance. Compared to traditional welding processes, exothermic welding molds are safer and easier to operate, require no external energy source, and are suitable for a variety of complex environments, including humid and confined spaces, as well as those prone to flammable and explosive environments. When used with exothermic welding powder, they can create a durable and reliable connection in tens of seconds, significantly saving labor time and reducing maintenance costs. Currently, this technology has been successfully applied in projects such as offshore wind power, high-speed rail signaling systems, smart city IoT base stations, and chemical explosion-proof grounding, demonstrating excellent adaptability and connection performance. Industry experts believe that the continuous innovation of exothermic welding molds is driving the electrical connection industry towards greater efficiency, intelligence, and reliability, providing critical support for the construction of new energy facilities and new infrastructure.

Recently, as global requirements for power safety and lightning protection grounding technology continue to rise, exothermic welding powder (Exothermic Welding Powder), as a highly efficient and reliable metal joining material, has become a focus of industry attention. This technology achieves molecular-level metal welding through high-temperature chemical reactions. It is widely used in grounding systems and permanent conductor connections in power, communications, transportation, and other fields, providing a solid foundation for the safe operation of critical infrastructure. Exothermic welding powder, with a copper-based composite material as its core, produces ultra-high-temperature liquid metal through a thermite reaction, achieving high-strength welding between conductors. Compared to traditional mechanical joining or welding processes, this technology requires no external power source or complex equipment, is simple to operate, and is highly adaptable, capable of stable operation in outdoor, humid, and even underwater environments. The resulting welded joints offer excellent conductivity, strong corrosion resistance, and a long lifespan. They effectively prevent problems such as loosening and oxidation, significantly improving system safety and stability. Currently, this technology has been successfully applied in new energy and infrastructure projects such as photovoltaic power plants, wind power generation, high-speed railways, and 5G base stations, providing a low-resistance, highly reliable connection solution for grounding systems. Industry experts indicate that the promotion of exothermic welding powder will further promote the standardization and intelligent development of lightning protection and grounding technology, injecting new impetus into global energy transformation and infrastructure construction.
