An Industry White Paper on Precision, Performance, and Global Sourcing.
Lost wax casting, or investment casting, represents the pinnacle of metallurgical precision. At JUNLONG Machinery Co., Ltd., we transform industrial requirements into high-performance mechanical components using carbon steel, alloy steel, and stainless steel. Founded in 2014 in Weifang, Shandong, our 60,000 square meter facility serves as a hub for Information Gain in the casting industry, providing more than just parts—we provide technical certainty.
With an annual production capacity of 20,000 tons, our processes are optimized for high-tech industries including automotive, rail transportation, and aerospace. The synergy between our 30+ engineering technicians and automated casting lines ensures that every part meets the rigorous E-E-A-T standards required by global procurement officers in the US, Germany, and Italy.
From mold design and tool making to precision casting and CNC machining, we offer a vertical integration that reduces lead times by 30% compared to fragmented suppliers.
Operating under ISO 9001, TS 16949, and UL certifications, we ensure that every mechanical part complies with international environmental and safety regulations.
Located in Shandong’s industrial heartland, we leverage world-class logistics to provide door-to-door localization support for enterprises in Europe and North America.
Where Precision Meets Heavy-Duty Performance
Our castings serve as the backbone for excavators and harvesters, providing wear-resistant alloy steel components that withstand extreme soil friction and load cycles.
Supplying OEM train and railway parts requires 100% flaw detection. Our investment steel castings ensure safety at high speeds through superior grain structure.
Stainless steel 316 valves and connecting rods manufactured via lost wax casting offer unparalleled corrosion resistance for maritime and petroleum machinery.
JUNLONG utilizes internationally advanced automated casting production lines. Our physical and chemical analysis laboratory is equipped with:
Integrating AI-driven simulation for fluid dynamics during the pouring process to eliminate turbulence-induced defects before the first mold is even created.
Our facility is transitioning to carbon-neutral energy sources, satisfying the "Environmental, Social, and Governance" (ESG) requirements of modern global enterprises.
Combining 3D printed wax patterns with traditional lost wax casting allows for rapid iteration of mechanical parts without the initial cost of hard tooling.
For new projects, mold development typically takes 15-20 days, followed by sample production within 7 days. Mass production cycles range from 30 to 45 days depending on complexity and volume.
We specialize in carbon steel (WCB, LCC), alloy steel (4140, 8620), and stainless steel (304, 316, 17-4PH). We can also customize chemical compositions based on specific ASTM or DIN standards.
We provide full material heat number traceability, 3.1 certification, and third-party inspection reports (SGS/TUV) upon request, ensuring compliance with TS 16949 standards.
Yes, we are a one-stop supplier. Our workshop includes horizontal/vertical machining centers, CNC lathes, and grinding machines. Surface treatments include galvanizing, powder coating, and electropolishing.
