Founded in 2014 and headquartered in the industrial hub of Weifang, Shandong, JUNLONG Machinery Co., Ltd. has established itself as a premier destination for high-complexity stainless steel pump valve investment castings. Spanning a state-of-the-art 60,000 square meter facility, our factory operates at an annual production capacity of 20,000 tons.
We are not just a manufacturer; we are an integrated engineering partner. Our team of 200+ dedicated professionals, including 30+ senior engineering technicians, utilizes advanced automated casting production lines and comprehensive physical-chemical analysis equipment to ensure every component exceeds international standards.
The global demand for stainless steel pump valve investment castings is experiencing an unprecedented surge, driven by the expansion of the chemical processing, desalination, and green energy sectors. Procurement heads at Fortune 500 companies now prioritize "Total Cost of Ownership" (TCO) over simple unit pricing, focusing on the longevity, corrosion resistance, and precision of components manufactured through the Lost Wax Casting process.
Global supply chains face the triple threat of logistics volatility, material scarcity, and tightening environmental regulations. JUNLONG Machinery mitigates these risks through:
Transitioning to 4.0 automation with robotic shell-building lines to eliminate human error in the investment casting process, ensuring 0.05mm tolerances.
Utilizing Spectrometer testing and X-ray flaw detection to guarantee the molecular integrity of every valve body and impeller casting we produce.
Future-proofing through wax recycling systems and energy-efficient induction furnaces to reduce the carbon footprint of industrial procurement.
Providing high-reliability solutions to global industry leaders across diverse specialized fields.
Wear-resistant components for modern harvesting and irrigation systems.
High-pressure valve bodies and fluid control parts for extreme environments.
Precision engine brackets and chassis components for Tier-1 suppliers.
Heavy-duty structural castings for excavators and material handling equipment.
Safety-critical precision steel parts for high-speed rail and metro networks.
Our commitment to reliability is backed by world-class certifications. JUNLONG Machinery is proud to hold ISO 9001 and TS 16949, alongside UL listings for specific product lines. These are not just badges; they represent our rigorous process control over every production detail—from raw material spectrum analysis to the final dimensional inspection of machined parts.
