Engineered for High-Performance Industrial Applications
Investment casting, often referred to as the "Lost Wax" process, remains the gold standard for producing complex, near-net-shape metal components. In the current global industrial paradigm, stainless steel investment casting is no longer just a manufacturing method; it is a critical enabler for industries requiring high corrosion resistance, hygienic properties, and exceptional strength-to-weight ratios.
The global market for precision casting is witnessing a significant shift toward automated foundries. Enterprises in Europe and North America are increasingly sourcing from integrated OEM partners who can provide not just raw castings, but fully machined, surface-treated, and quality-tested assemblies. This move towards "Value-Added Manufacturing" is where the true competitive advantage lies.
JUNLONG Machinery Co., Ltd., founded in 2014, has evolved into a global benchmark for OEM Stainless Steel Investment Casting. Located in Weifang, Shandong—the heart of China's heavy industry corridor—we leverage over 60,000 square meters of state-of-the-art production space.
With a dedicated workforce of over 200 professionals, including a core team of 30+ engineering technicians, we specialize in transforming complex designs into reality using materials such as carbon steel, alloy steel, and premium stainless steel grades (304, 316, 17-4 PH).
Weifang, Shandong offers a unique ecosystem where raw material refiners, mold makers, and logistics hubs are within a 50km radius, reducing lead times by 30% compared to global competitors.
Our facility is equipped with internationally advanced automated casting production lines, ensuring consistent shell building and pouring, which minimizes human error and maximizes metallurgical stability.
Every batch undergoes comprehensive testing, including spectrometer chemical analysis, tensile testing, and non-destructive testing (MPI/UT) to meet the strict mechanical property requirements of mid-to-high-end clients.
High-durability components for harvesters and farming equipment designed to withstand abrasive soil conditions.
Corrosion-resistant stainless steel valves and pump components for offshore and onshore drilling environments.
Safety-critical chassis and engine components exported to Germany, the USA, and Italy.
Construction machinery such as excavators, loaders, and cranes relies on high-strength, wear-resistant castings to support heavy-duty operations. We provide customized precision casting services, producing structurally complex and high-load-bearing components to ensure machinery remains durable and efficient in harsh environments like mining and road construction.
1. Mold Manufacturing: In-house CNC tool shop ensures dimensional accuracy at the source.
2. Precision Casting: Lost wax process utilizing advanced robotic dipping for uniform ceramic shells.
3. Machining: Equipped with horizontal and vertical machining centers (HMC/VMC), CNC lathes, and grinders.
4. Surface Treatment: Pickling, passivating, electropolishing, and powder coating available on-site.
Customer Value: By consolidating the supply chain, we eliminate communication costs and quality risks associated with multi-factory collaboration, enabling full-process traceability with a single point of responsibility.
Staying ahead through innovation and ESG compliance
Using casting simulation software (like Magma or ProCAST) to predict porosity and shrinkage before a single drop of metal is poured.
3D printing wax patterns for rapid prototyping, allowing for low-volume production without the high cost of traditional tooling.
Transitioning to induction furnaces with higher energy efficiency and closed-loop water cooling systems to reduce environmental impact.
Expert insights into stainless steel investment casting
Stainless steel offers exceptional corrosion resistance, heat resistance, and high strength. Grades like 316L are ideal for marine and medical applications, while 17-4PH provides high hardness for structural industrial parts. Investment casting allows for intricate details that machining alone cannot achieve economically.
For new projects, mold design and sampling usually take 3-4 weeks. Once the sample is approved, mass production typically ranges from 4-6 weeks depending on volume and complexity. JUNLONG’s integrated facility can often compress these timelines by performing machining in-house.
We implement a strict quality management system certified by ISO 9001 and TS 16949. Every heat of metal is tested via spectrometer, and every batch of parts is tracked with unique heat numbers. We provide full material certifications and dimensional inspection reports for every shipment.
Yes, one of the greatest "Information Gains" of investment casting is the ability to consolidate multiple components into a single casting. This reduces weight, eliminates weld-point failures, and lowers overall assembly costs.
