View DetailsAs the economic epicenter of Peru and the gateway to the Andean mining corridor, the metropolitan area of Lima and Callao represents a rapidly upgrading industrial ecosystem. Demands for infrastructural efficiency, coupled with strict environmental regulations, have catalyzed a major shift toward high-grade stainless steel castings across several key sectors.
Particularly, Lima's vast coastal processing hubs, marine vessel maintenance shipyards (SIMA Callao), and desalination operations face severe saline-alkali atmospheric degradation. Standard cast irons or carbon steels fail prematurely under these aggressive chloride environments. By introducing optimized chromium-nickel-molybdenum alloy matrices (such as CF8M / 316L), local operators can extend component life cycles by up to 300%.
Founded in 2014, JUNLONG Machinery Co., Ltd. has established itself as an international benchmark for high-performance precision casting and finished machining. Located in Weifang, Shandong, our state-of-the-art facility covers an expansive 60,000 square meters and maintains an annual production capacity exceeding 20,000 tons of precision investment castings.
Our workforce features over 200 dedicated employees, including a specialized R&D engineering team of 30+ technicians. We bridge the gap between design and physical delivery by specializing in custom alloys, carbon steels, and corrosion-resistant stainless steels. Our operations are fully integrated, providing a single point of accountability from initial shell-mold design to ready-to-assemble components.
How automation and advanced logistics protect your operations from inflation and raw material volatility.
By using climate-controlled robotic shell assembly lines, we guarantee consistent drying times, eliminating structural defects and ensuring uniform surface finishes on complex castings.
We eliminate downstream machining overhead by housing high-precision 4-axis and 5-axis vertical machining centers inside our foundry. Get ready-for-assembly parts shipped straight to Peru.
Every casting heat is monitored via optical emission spectrometers, ultrasonic testing, and magnetic particle inspection, complete with mill test reports (MTR) matching EN 10204 3.1 standards.
To operate safely within high-risk industrial environments such as mining transport or fluid control, compliance is non-negotiable. JUNLONG Machinery operates under a strict, continuously audited QA structure. We hold certifications for ISO 9001, IATF 16949 (Automotive Standard), and UL, ensuring structural integrity and precise chemical profiles across all production runs.
We invest in top-tier machining and analysis equipment to maintain strict micron-level tolerances.
Our castings are engineered to address specific failures, reducing maintenance costs and operational downtime.
