In the modern industrial landscape, the demand for materials that can withstand extreme thermal stress, corrosive atmospheres, and high-pressure mechanical loads has skyrocketed. Nickel alloy steel investment casting—often referred to as "Superalloy Lost Wax Casting"—stands at the pinnacle of this technological evolution.
Globally, industries such as aerospace propulsion, deep-sea oil exploration, and advanced chemical processing are shifting toward nickel-based superalloys (like Inconel, Monel, and Hastelloy). These materials are not merely "preferred"; they are critical for operational safety and equipment longevity. As an experienced OEM Nickel Alloy Steel Investment Casting Supplier, we recognize that our components are the heart of machines that power the world.
JUNLONG Machinery Co., Ltd. was founded in 2014. Located in Weifang, Shandong, the company covers a total area of 60,000 square meters and has an annual production capacity of 20,000 tons of precision castings and machined finished parts. It specializes in materials such as carbon steel, alloy steel, and stainless steel.
With over 200 employees, including more than 30 engineering technicians, the company is a high-quality casting supplier integrating precision casting and deep processing. Our facilities are equipped with internationally advanced automated casting production lines and comprehensive physical and chemical analysis equipment.

Investment casting, or "lost wax casting," is the preferred method for producing complex nickel alloy parts because it allows for intricate geometries and thin-walled structures that are impossible to achieve with traditional sand casting or forging.
We work with various nickel-base grades including Inconel 625, 718, and Hastelloy C276. These alloys contain high percentages of Chromium and Molybdenum, providing unparalleled resistance to pitting and stress corrosion cracking.
Our Automated Precision Casting lines ensure consistency. Automated shell building and robotic wax injection minimize human error, ensuring that every batch of OEM parts meets the rigorous TS 16949 standards.
Physical and chemical analysis is mandatory. We utilize Spectrometers, X-ray flaw detection, and Ultrasonic testing to ensure that internal metallurgical integrity is perfect before the part ever leaves our factory.
Full Industrial Chain Integration: Unlike many Western suppliers who outsource finishing, JUNLONG provides a Seamless Connection from mold manufacturing to final surface treatment. This reduces lead times by up to 30%.
Cost-to-Performance Ratio: China’s mature supply chain for raw nickel and molybdenum, combined with large-scale industrial efficiency, allows us to offer high-tech precision castings at a highly competitive price point without compromising quality.
Engineering Depth: With over 30 dedicated engineering technicians, we assist global clients in "Design for Manufacturability" (DfM), optimizing part weight and strength through simulation software before the first wax pattern is even made.
Turbocharger components and high-temperature exhaust manifolds that require extreme thermal stability.
Downhole drilling tools and subsea valve bodies that must withstand sour gas and high-salinity environments.
Impellers, pump casings, and mixing components for processing highly corrosive acids and alkalis.
High-precision structural components that ensure the safety and efficiency of high-speed rail networks globally.
The industry is moving toward "zero-defect" manufacturing. By creating a digital twin of the casting process, we can predict thermal shrinkage and gas porosity before the metal is even poured. This is critical for expensive nickel alloys where scrap costs are high.
The global push for ESG (Environmental, Social, and Governance) means foundries must adopt green energy and waste recycling. Our facility focuses on wax recycling and energy-efficient induction furnaces to reduce our carbon footprint.
Hybrid manufacturing is the future. We use 3D-printed wax patterns for rapid prototyping, allowing clients to test nickel alloy components in weeks rather than months, significantly accelerating their R&D cycles.
As machinery becomes more compact, tolerances are tightening. We are now routinely delivering parts with dimensional accuracy that eliminates the need for secondary machining in 40% of cases.
Ensuring process control over every production detail: ISO 9001, TS 16949, and UL Certified.
