Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, which grew from Xianyang Kelong Rubber Products Institute.
It Is a Technological innovation company integrating R&D, production and sales, concentrates on hydraulic seal set, high-pressure hose, coal mine auxiliary transportation equipment, repairing coal mine auxiliary transportation equipment, technological service and etc.
Our products have been widely applied to Coal mining industry, Civil Aviation, High speed railway, Engineering machinery, Wind power, and the specific high-demand maritime requirements of Hamburg's industrial sector. The high-quality products and services are trusted by customers all over the world.
Hamburg, the "Gateway to the World," is not just a historic port city; it is a global powerhouse of industrial innovation. As the third-largest port in Europe, the Port of Hamburg creates a massive demand for high-performance rubber seal products. From the hydraulic cranes managing thousands of containers at the Altenwerder terminal to the massive dredging machines maintaining the Elbe River's depth, sealing technology is the invisible backbone of the city's logistics infrastructure.
The Aerospace Industry in Hamburg, anchored by the massive Airbus production facility in Finkenwerder, represents another critical market. Aviation-grade rubber seals must withstand extreme temperature fluctuations and pressure changes. Local exporters and companies in Hamburg are increasingly looking for suppliers who can provide NBR, FKM, and PTFE solutions that meet stringent European aviation safety standards.
Furthermore, Northern Germany is at the forefront of the Energy Transition. The offshore wind farms in the North Sea, serviced through Hamburg's specialized maritime companies, require seals that can survive the highly corrosive saltwater environment. Our rotary shaft seals and V-rings are specifically engineered to provide protection against contamination, a vital requirement for the longevity of wind turbine gearboxes.
Industry Trends in Hamburg: We are observing a shift toward "Smart Sealing." Companies in Hamburg are moving away from standard off-the-shelf components toward customized, AI-designed polymer solutions. There is also a significant trend toward sustainability—reducing friction to save energy and using biodegradable hydraulic fluids, which requires new chemical compatibility in rubber formulations.
The company is ranked among the top three in the domestic machine sealing industry. With high-pressure rubber hoses and frame-type handling vehicles expected to enter the top three globally within two years, we currently hold an 8% market share in domestic high-end sectors.
Ultra-tough, high-pressure hydraulic hoses installed in Hamburg's automated guided vehicles (AGVs) for rock-solid performance.
Rigorously tested seals ensure heavy-lift cranes on the Elbe River remain stable under extreme North Sea weather conditions.
Innovative sealing designs combining flexibility and strength for North Sea oil and gas platforms serviced from Hamburg.
Upgraded equipment efficiency with our specialized high-pressure hoses for offshore wind nacelle hydraulics.
Over 500 employees and 180+ technicians. We invest 7%+ of our annual revenue into R&D to stay ahead of European industrial standards.
With ISO and IRIS certifications, our professional team conducts strict multi-point checks throughout the production process.
Utilizing Austrian DMH equipment and production technology alongside Italian-imported hydraulic hose manufacturing lines.
The German industrial market, particularly in high-tech hubs like Hamburg and Bremen, is defined by a demand for "Null-Fehler-Qualität" (Zero-Defect Quality). For rubber seal exporters, this means that providing a standard product is no longer sufficient. Material science has become the primary differentiator. We utilize advanced Polyurethane (PU) with enhanced hydrolysis resistance, which is critical for the humid, maritime climate of Northern Germany.
In the Port of Hamburg, seals are often exposed to mineral oils, biodegradable hydraulic fluids, and seawater simultaneously. Our NBR (Nitrile Butadiene Rubber) and FKM (Viton) compounds are formulated to resist swelling and chemical degradation. For high-speed rail applications connecting Hamburg to the rest of Europe, our seals are tested for vibration damping and long-term fatigue resistance, ensuring safety at speeds exceeding 300 km/h.
Leveraging AI-driven design tools, we can simulate the deformation of a seal under pressure before the first prototype is ever molded. This reduces lead times for our Hamburg-based partners in the mechanical engineering sector. By optimizing the lip geometry of our Double Lip Wiper Seals, we minimize friction by up to 15%, directly contributing to the "Green Logistics" initiatives currently sweeping through German industry.
