In the world of Hot Products Manufacturing, reliability is not just a buzzword—it's a safety requirement. At JUNLONG Machinery Co., Ltd., our decade of experience (Experience) in Shandong’s industrial heartland, combined with a 30-strong engineering team (Expertise), ISO/TS certifications (Authoritativeness), and a 20,000-ton annual output (Trustworthiness), ensures that every component exceeds global standards.
China's casting industry has transitioned from "Mass Production" to "Precision Engineering." By sourcing from a specialized China factory, global enterprises gain Information Gain—better material science insights, integrated mold design, and a 30-40% reduction in TCO (Total Cost of Ownership) through optimized logistics and material utilization.
Modern procurement directors aren't just looking for parts; they are looking for supply chain resilience. Our integrated manufacturing model—from 3D mold prototyping to CNC finishing—addresses the urgent need for shorter lead times and transparent quality tracking that European and American markets demand.

The industry is moving toward decarbonization. JUNLONG is integrating energy-efficient induction furnaces and sand recycling systems to meet the ESG (Environmental, Social, and Governance) requirements of global fortune 500 partners. We are helping our clients reduce their Scope 3 emissions at the source.
By using AI-simulated pouring analysis, we predict casting defects before the first drop of molten steel hits the mold. This digital transformation allows us to produce "Hot Products" with zero-defect tolerance for high-stakes industries like aerospace and high-speed rail.
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.
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. We serve as a key supplier for automotive, rail transportation, engineering machinery, and petroleum machinery.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment, the company significantly enhances manufacturing efficiency and product quality stability.
Leveraging strong engineering capabilities and a complete quality control system, we export to Germany, the United States, Italy, Canada, and other countries, maintaining a high-tech industry supplier status.
From mold manufacturing to surface treatment, we eliminate multi-factory delays. Our workshop includes horizontal/vertical machining centers, CNC lathes, and specialized grinders for final finished parts.
We specialize in a wide array of industrial metals, primarily focused on carbon steel, alloy steel, and various grades of stainless steel (including OEM 316). These materials are chosen for their durability in heavy-duty sectors like shipbuilding and auto manufacturing.
We utilize "Lost Wax Casting" (Investment Casting) technology. This process allows for extreme dimensional accuracy and a superior surface finish, reducing the need for extensive secondary machining while maintaining tight tolerances for parts like pump valves and engine components.
Thanks to our in-house mold manufacturing and automated lines, we typically deliver prototypes within 3-4 weeks. Mass production cycles depend on complexity but are significantly shorter than traditional sand casting methods due to our integrated 20,000-ton capacity.
Yes. We understand that a truck brake lever used in the extreme cold of Canada requires different heat treatment than one used in the oilfields of Texas. Our engineering team customizes material compositions and surface treatments based on the end-user's localized environment.
Our company continuously pursues and improves product quality to achieve high customer satisfaction through process control over every production detail.
