Engineered for excellence, delivered with precision.
The global demand for corrosion resistant investment castings has reached an inflection point. As industries ranging from chemical processing to renewable energy push the boundaries of operational environments, the requirement for components that can withstand saline, acidic, and high-temperature stress is paramount. Modern procurement strategies are no longer focused solely on cost-per-unit but on Total Cost of Ownership (TCO) and Information Gain regarding material lifecycle.
Leading enterprises in Germany, the United States, and Japan are increasingly seeking "Integrated Manufacturing Partners" rather than simple foundries. This shift is driven by the need for semantic quality—where the casting process is digitally traced, and the metallurgical integrity is verified through AI-driven physical and chemical analysis.
Tailored solutions for Marine, Oil & Gas, and Desalination plants where chloride-induced stress corrosion is a constant threat.
Integrating CNC vertical and horizontal machining centers to deliver finished parts with tolerances within microns.
Expertise in Duplex Stainless Steels, Superalloys, and OEM-specific carbon steel grades for diverse industrial stress profiles.
Founded in 2014 and located in the industrial hub of Weifang, Shandong, JUNLONG Machinery Co., Ltd. has established itself as a premier global casting leader. Covering 60,000 square meters, our facility represents the pinnacle of automated precision casting.
With an annual production capacity of 20,000 tons, we specialize in transforming raw materials like carbon steel, alloy steel, and stainless steel into high-tech precision components for global leaders in Europe and America.
The future of investment casting lies in the synergy between traditional "Lost Wax" techniques and Industry 4.0 digitalization. Our roadmap focuses on three pillars:
As a key supplier for photovoltaic power plants and heavy-duty commercial vehicles, we are committed to providing "Information Gain" through comprehensive mechanical property testing and non-destructive evaluation (NDE).
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment, we enhance manufacturing efficiency and product quality stability.
From mold manufacturing to surface treatment, all key processes are completed in-house. This eliminates communication costs and quality risks associated with multi-factory collaboration.
Brake systems & engine components.
Corrosion-resistant valves & pumps.
High-load structural investment parts.
Durable harvester & machinery parts.
Trust is built on verification. JUNLONG Machinery is proud to hold ISO 9001, TS 16949, and UL certifications. These aren't just badges; they represent our commitment to process control over every production detail.
Expert insights into corrosion-resistant casting technology.
We utilize specific grades of stainless steel (like 316L, 304, and Duplex) and specialized surface treatments like passivation and electropolishing to create a protective oxide layer that resists chemical and environmental oxidation.
By using automated wax injection and robotic shell building, we maintain extreme consistency. Our CNC machining centers then refine critical tolerances to ensure every part meets the sub-millimeter specifications required by industries like aerospace and automotive.
Yes. Our engineering team works with clients to develop custom metallurgical recipes, including high-manganese steel and specific carbon steel variants, to balance hardness, ductility, and corrosion resistance.
For standard components, tooling takes 2-4 weeks, with production following in 4-6 weeks. However, our integrated manufacturing process often allows us to beat industry averages by 15-20%.
Comprehensive casting services for every industrial challenge.
Integrate our advanced management and technical resources into your supply chain. Let’s build the future of precision manufacturing together.
