Founded in 2014, JUNLONG Machinery Co., Ltd. has emerged as a powerhouse in the Shandong casting cluster, specializing in the high-precision "Lost Wax" investment casting process. Operating out of a 60,000 square meter facility in Weifang, we maintain an annual production capacity of 20,000 tons of finished components. Our engineering team, comprising over 30 senior technicians, bridges the gap between raw metallurgy and high-tolerance mechanical engineering.
Unlike regional foundries, Chinese factories like Junlong offer a vast spectrum of alloys—ranging from ASTM A216 Carbon Steel to Duplex Stainless Steel and specialized Chrome-Moly Alloy Steels—all under one roof.
Leveraging advanced mold-making technologies and 3D printing wax patterns, we reduce the lead time from design to "first article" by 40% compared to traditional Western manufacturing cycles.
Our commitment to automotive excellence is solidified by ISO 9001 and TS 16949 (IATF 16949) certifications, ensuring every part—from engine brackets to rail clips—meets the rigorous safety standards of the global automotive supply chain.
The global automotive sector is undergoing a paradigm shift towards Electric Vehicles (EV) and lightweight construction. As a leading China precision casting automotive parts factory, we are at the forefront of this transition. Precision investment casting allows for the creation of near-net-shape components that minimize waste and maximize structural integrity.
Lightweighting: By utilizing high-strength alloy steels, we enable manufacturers to reduce the weight of chassis components without compromising on tensile strength or fatigue resistance. This is critical for extending the range of modern EVs.
Digital Twin Integration: Our factory utilizes simulation software to predict metal flow and solidification, virtually eliminating defects like porosity before the first drop of molten steel is poured. This "zero-defect" philosophy is what defines the next generation of China automotive factories.
From infrastructure to extreme performance, our castings power the world's most critical systems.
Engine brackets, transmission housings, and turbocharger components requiring high thermal stability and precision.
Wear-resistant components for harvesters and tractors designed to withstand abrasive soil conditions.
Heavy-duty fastening systems and structural parts for high-speed rail networks across Europe and Asia.
Corrosion-resistant stainless steel spare parts and oilfield cable protectors (Alloy Steel).
Load-bearing components for excavators and cranes, engineered for extreme mechanical fatigue resistance.
Complex internal geometries for fluid control systems, cast with high dimensional accuracy.
We are not just a casting foundry; we are a one-stop precision manufacturing partner. By integrating mold design, investment casting, heat treatment, and CNC precision machining, we provide a seamless path from concept to finished assembly.
We implement a comprehensive testing regime including Spectrometric Analysis, Magnetic Particle Inspection (MPI), and Ultrasonic Testing (UT) to ensure internal metallurgical integrity for all exported components.
Located near major ports, we optimize shipping costs and timelines for our clients in the USA, Germany, Italy, and Canada, providing transparent tracking and customs documentation.
Our facility is equipped with internationally advanced automated casting production lines and physical/chemical analysis equipment, ensuring the highest stability in product quality.
