JUNLONG Machinery Co., Ltd., established in 2014, represents the pinnacle of Chinese industrial casting evolution. Headquartered in Weifang, Shandong—a global hub for metallurgical expertise—our 60,000 square meter facility bridges the gap between traditional craftsmanship and Industry 4.0 automation. With an annual capacity of 20,000 tons, we don't just manufacture parts; we engineer reliability for the world's most demanding sectors.
Our commitment to E-E-A-T principles is reflected in our robust technical team of over 30 engineering specialists and a workforce of 200+ dedicated professionals. We specialize in complex geometries using Carbon Steel, Alloy Steel, and Stainless Steel, ensuring every component meets the stringent safety and performance standards of global markets.
Our "Lost Wax" investment casting process is a journey of precision. By integrating AI-driven simulation software, we predict solidification patterns and minimize internal defects before the first mold is even created.
Utilizing internationally advanced automated facilities to ensure dimensional stability across high-volume runs. This reduces human error and enhances surface finish quality.
Our in-house labs conduct spectral analysis, tensile testing, and non-destructive testing (NDT) to guarantee metallurgical integrity for critical components.
We provide localized support for Tier-1 clients in the USA, Germany, Italy, and Canada, adhering to ISO 9001, TS 16949, and UL certifications.
The "China Advantage" in 2024 is no longer just about cost—it's about ecosystem density. Located in the industrial heartland of Shandong, JUNLONG Machinery leverages a hyper-local supply chain for raw materials, heat treatment, and specialized surface coatings. This reduces lead times by 30% compared to fragmented international competitors.
Forging high-toughness components for harvesters and tractors that withstand extreme soil friction and load cycles.
Our cable protectors and valve components are engineered for deep-sea and high-pressure drilling environments, preventing costly downtime.
Safety-critical castings for cooling systems and structural components, meeting the zero-defect requirements of the TS 16949 standard.
Corrosion-resistant stainless steel castings designed for prolonged exposure to saltwater, ensuring structural longevity of ship hardware.
Heavy-duty parts for excavators and material handling machinery, focused on wear resistance and impact strength.
Combining aesthetic surface finishes with structural integrity for modern commercial buildings and high-end installations.
The precision casting industry is entering a "Digital Twin" era. JUNLONG is currently investing in 3D sand printing and real-time sensor monitoring of the molten metal pouring process. Our goal is to achieve Carbon Neutral Casting by optimizing energy consumption in our induction furnaces and implementing full-scale sand recycling systems.
Most buyers focus on price-per-kilogram. However, the true value lies in Net Shape Precision. Our advanced casting reduces machining allowances, saving up to 20% in post-processing costs and material waste. This is the "Information Gain" we provide: engineering solutions that optimize the entire product lifecycle, not just the casting phase.
