The global railway industry is undergoing a paradigm shift driven by high-speed rail expansion, urbanization in emerging economies, and the "Green Mobility" initiative. Investment steel casting, particularly the lost-wax process, has become the backbone of this transformation. As a leading Custom Railway investment steel casting Manufacturer, JUNLONG Machinery provides the critical components required to sustain safety, durability, and efficiency in modern transit systems.
The demand for high-strength, lightweight steel components is surging. North American freight and European high-speed networks require components that can withstand extreme fatigue cycles and varied climatic conditions.
Investment casting allows for near-net-shape production of complex geometries that are impossible or too costly via traditional forging or sand casting, reducing material waste by up to 30%.
Modern "Green Foundries" are integrating circular economy principles, recycling wax and scrap metal to minimize the carbon footprint of railway infrastructure.
Founded in 2014, JUNLONG Machinery Co., Ltd. has established itself as a premier high-quality casting supplier. Based in Weifang, Shandong, our facility spans 60,000 square meters, housing the latest in automated precision casting technology.
We specialize in carbon steel, alloy steel, and stainless steel, with an annual capacity of 20,000 tons. Our team of over 200 dedicated professionals, including 30+ senior engineering technicians, ensures that every piece meets the rigorous standards of global industry leaders.
Integrating AI into the mold-filling and solidification simulation process to predict and eliminate casting defects before physical production begins. This shortens the OEM development cycle from months to weeks.
Pioneering the use of low-alloy high-strength (LAHS) steels that provide superior impact resistance at sub-zero temperatures, essential for Siberian or Scandinavian rail routes.
Utilizing robotic grinding and CNC machining centers (Horizontal/Vertical) to ensure micron-level tolerances for railway braking systems and coupling components.
Delivering high-precision castings across diverse high-tech sectors.
Couplers, bogie components, brake system hardware, and track fasteners designed for longevity.
Custom lost-wax components for harvesters and tractors, optimized for wear resistance.
Conquering extreme conditions with excavator buckets, loader joints, and heavy-duty supports.
Corrosion-resistant stainless steel parts for ship propulsion and spare parts.
High-pressure valves and pump components for rigorous oil and gas extraction environments.
Precision cast engine and chassis parts for global OEM automotive leaders.
Our facility is equipped with internationally advanced automated casting production lines. We adhere to ISO 9001, TS 16949, and UL certifications, ensuring every production detail is traced. Physical and chemical analysis equipment allows us to verify mechanical properties, ensuring 100% compliance with client specifications.
