In the current era of "Software-Defined Vehicles" and "Electrification," the demand for precision casting has evolved from simple mechanical support to high-performance structural integration. As a leading China Automobile Casting Components Manufacturer, JUNLONG Machinery Co., Ltd. recognizes that global OEMs (Original Equipment Manufacturers) are no longer just seeking a low-cost vendor but a strategic partner capable of providing Information Gain through material science and process optimization.
Our role in this ecosystem is defined by our ability to handle complex geometries and high-integrity materials like 16Mn steel and specialized alloy steels, which are critical for lightweighting—the primary technical route for extending EV range.

Specializing in Carbon Steel, Alloy Steel, and Stainless Steel. We utilize physical and chemical analysis to ensure grain structure integrity and tensile strength compliance for safety-critical parts like engine brackets and axle components.
Equipped with internationally advanced automated production facilities. Our lost wax investment casting process ensures dimensional tolerances within ISO standards, reducing the need for secondary machining by 30%.
From mold manufacturing to deep CNC machining and surface treatment. We eliminate supply chain fragmentation, providing a single point of accountability for Tier 1 and Tier 2 automotive suppliers.
Leveraging AI-enhanced simulation and rigorous testing (X-ray, MPI, Ultrasonic) to achieve nearly zero-defect manufacturing for high-load handling and agricultural machinery parts.
JUNLONG Machinery Co., Ltd. was founded in 2014 in Weifang, Shandong. Our facility covers 60,000 square meters and boasts an annual production capacity of 20,000 tons of precision castings. With over 200 dedicated employees, including 30+ engineering technicians, we integrate precision casting with deep processing.
Leveraging strong engineering capabilities, a complete quality control system, and advanced management systems, we have become a well-known brand manufacturer. Our products are exported to global powerhouses including Germany, the United States, Italy, and Canada.
Stringent automotive quality management systems that ensure process consistency from raw material melt to final shipment.
Compliant with safety and reliability standards required by North American and European markets.
Technical support available for global design teams, assisting in DFM (Design for Manufacturing) to optimize part weight and cost.
Committed to green manufacturing practices, recycling scrap metal, and optimizing energy consumption in our electric furnaces.
We serve as a key high-tech supplier for diverse industries requiring high-strength precision components.
Engine brackets, transmission housings, and steering components.
Load-bearing joints for excavators and heavy cranes.
Durable components for harvesters and tractors.
Valve bodies and cable protectors for offshore environments.
The automotive industry is facing unprecedented challenges in thermal management and battery weight. Our R&D team is currently focusing on Thin-Walled Casting Technology and High-Toughness Alloys that can withstand high-impact energy while reducing overall vehicle weight. By integrating AI-driven topology optimization, we help our clients redesign heavy forged parts into single-piece precision castings.
