In the modern industrial landscape, "Custom Casting Material" refers to much more than simple metal pouring. It represents a sophisticated intersection of metallurgy, fluid dynamics, and precision engineering. At JUNLONG Machinery Co., Ltd., we recognize that global industry leaders—from automotive giants to aerospace innovators—are no longer just looking for a "supplier." They are seeking a strategic partner capable of delivering Information Gain through material optimization and process transparency.
Since our founding in 2014 in Weifang, Shandong, we have evolved into a high-quality casting hub. Our facility doesn't just produce parts; we engineer reliability. By specializing in carbon steel, alloy steel, and stainless steel, we address the specific mechanical stresses required by heavy-duty commercial vehicles, railway systems, and petroleum machinery. Our 60,000 square meter facility serves as a testament to China's "Advanced Manufacturing" shift, moving from high-volume output to high-precision, tech-integrated solutions.
Equipped with internationally advanced automated production facilities, we enhance manufacturing efficiency and quality stability, meeting rigorous mechanical property testing for diverse materials.
Holding ISO 9001, TS 16949, and UL certifications, we ensure every detail of the production process is controlled, delivering products to Germany, USA, Italy, and Canada.
From mold manufacturing and precision casting to complex CNC machining and surface treatment, our vertical integration eliminates multi-factory collaboration risks.
The global procurement shift towards Chinese precision casting factories is driven by several macroeconomic factors. Custom casting material manufacturers in China have transitioned from being "low-cost alternatives" to "technology-first pioneers."
We are not just a casting supplier, but a one-stop precision manufacturing partner from concept to finished product. Through deep integration of advanced equipment, full-process quality control, and professional engineering support, we ensure high-quality, high-reliability casting solutions for our clients.
Integrated Manufacturing: Mold Manufacturing → Precision Casting → CNC Machining → Surface Treatment.
Machining Workshop: Equipped with horizontal/vertical machining centers, CNC lathes, and grinders to provide finished precision components.
Different sectors demand distinct "Custom Casting Material" profiles. Our engineering team specializes in tailoring metallurgical compositions to specific application environments:
Focus on weight reduction without compromising tensile strength. We provide brake levers, transmission components, and railway parts with superior fatigue resistance.
Equipment for farming requires extreme wear resistance. Our lost wax castings for harvesters and tractors withstand harsh soil and climate conditions.
Corrosion is the primary enemy. We utilize specialized stainless steel and alloy grades to produce pump valve accessories and ship parts that survive salt spray and high-pressure fluids.
Global procurement teams now prioritize E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness). They require factories that provide documented physical and chemical analysis, traceability of materials, and a commitment to green manufacturing trends. JUNLONG answers these needs by integrating ESG principles into our 20,000-ton annual production cycle.
1. Digital Twin Technology: Creating virtual replicas of casting molds to simulate metal flow, cooling rates, and potential porosity before physical production begins.
2. 3D Printed Sand Molds: For complex, low-volume custom material castings, 3D printing allows for geometries that were previously impossible with traditional tooling.
3. Sustainable Metallurgy: Increasing the ratio of recycled content and implementing energy-efficient induction furnaces to reduce the carbon footprint of precision castings.




Our facility is a hub of tech-innovation, featuring comprehensive testing equipment for mechanical properties, ensuring we remain a global leader in precision casting.
