Premium industrial fluid dynamics engineered for critical hydraulic pathways. Seamlessly integrated into local material-handling fleets and automotive stamping lines.
Analyzing Fluid Power and Polymer Seal Demands in Modern Smart Manufacturing & Heavy Infrastructure
Detroit, Michigan, represents more than the historical focal point of American automotive manufacturing. Today, it has evolved into a powerhouse of advanced multi-industry manufacturing, smart automation, aerospace design, defense contracting, and Great Lakes maritime infrastructure. The performance requirements for hydraulic fluid conveyance systems and advanced polymer seals in this industrial corridor have undergone a massive shift towards extreme resilience, environmental compatibility, and long-term durability under continuous cycle stresses.
Modern stamping operations, automated assembly plants, and forging systems operating throughout Wayne, Oakland, and Macomb counties require hydraulic lines that can withstand pressures exceeding 5,000 PSI while resisting chemical degradation from synthetic fire-resistant fluids. Furthermore, heavy machinery components in local mining, infrastructure expansion, and logistics hubs demand dynamic hydraulic seal kits engineered to minimize friction, stop oil leaks, and operate flawlessly under fluctuating temperatures from harsh Michigan winters to high-heat foundry settings.
Information Gain Matrix: Traditional standard hoses degrade 40% faster in high-frequency thermal cycling environments typical of Detroit's automated welding cells. Using advanced wire-braid and custom PTFE formulations ensures uninterrupted production uptime.
On a global scale, the industrial fluid power transmission market is shifting rapidly towards sustainability and digitalization. The rise of bio-degradable oils has mandated new polymer formulations for interior hose liners. Conventional elastomers often swell or degrade when exposed to synthetic esters and bio-oils, causing premature failure. Kelong's newly developed NBR and FKM compounds address these ecological transitions, providing leak-free performance without sacrificing pressure limits or line flexibility.
A Technological Pioneer in Advanced Elastomeric Seals & High-Pressure Hydraulic Hoses Since 1996
Shaanxi Kelong New Materials Technology Co., Ltd. was established in 1996, emerging from the Xianyang Kelong Rubber Products Institute. Over the last two decades, Kelong has built a reputation as a leading innovator in R&D, manufacturing, and global distribution of advanced hydraulic sealing systems, heavy-duty wire-braided hoses, and machinery repair solutions.
Kelong stands in the top three of the domestic coal mining machinery sealing industry, while our high-pressure rubber hoses and heavy transport systems are projected to secure top three spots within the next two years. Our key seal kits and high-pressure hose products currently command an 8% share of the domestic market, serving critical sectors such as Aerospace, High-Speed Rail, Wind Power Generation, and Heavy Construction Equipment globally.

Combining European Machine Precision with Premium Polymer Formulations
Kelong's commitment to high quality relies heavily on high-precision processing machinery. Our sealing product line integrates technology and production systems from DMH Company in Austria. This ensures that customized high-performance seals (ranging from 10mm to over 2000mm in diameter) maintain dimensional tolerances under 0.05mm. For the fluid conveyance line, our hydraulic hose facility features high-efficiency braided and spiral production equipment imported from Italy, ensuring consistent tension control, precise steel wire layout, and optimal adhesion between rubber layers.
DMH CNC systems allow for fast, tool-free machining of custom polyurethane, elastomer, and PTFE sealing profiles. This flexibility makes it easy to support prototype development and replace worn components on older industrial machinery in the Detroit area without long tooling delays.
We work with materials like NBR, FKM, POM, PA, and customized polyurethanes designed to handle temperatures from -45°C up to +200°C.
Our hose manufacturing plant uses Italian high-speed braiding systems to keep consistent wire angle offsets and layout tension. This precision results in a hydraulic hose that can withstand higher dynamic impulse cycles than typical industry standards, minimizing length changes under pressure.
Ideal for heavy industrial applications in automotive stamping presses, hydraulic gantries, and subsea material handling equipment.
Our facilities operate under ISO 9001 and IRIS quality management systems. More than 7% of annual revenue is reinvested back into our R&D center to develop advanced materials. This focus on product quality and technical innovation helps keep our engineering standards at the forefront of the industry.

Innovating Next-Generation Smart Fluid Power Technologies
As industrial automation enters the era of Industry 4.0, Kelong is focusing its research on smart predictive technologies. The integration of IoT sensors within hydraulic systems allows for real-time condition monitoring of fluid temperature, line pressure, and seal wear. This predictive maintenance approach helps identify potential component wear before a failure occurs, reducing unscheduled downtime in high-throughput automotive assembly plants and critical infrastructure projects.
Our material science roadmap includes developing bio-based polyurethanes and self-lubricating seal materials to reduce friction and wear. In our hose line, we are researching high-tensile carbon-fiber hybrid braids to reduce total hose weight by 30% while retaining high burst pressure limits. This weight reduction is particularly beneficial for lightweight robotic arms and aerospace hydraulic actuators.
With an engineering workforce of 180+ technicians and an annual R&D reinvestment of over 7%, we deliver consistent quality and scale for heavy industry demands.
Operating under ISO 9001 and IRIS standards, our quality control team tests every production run to ensure compliance with international hydraulic specifications.
