Engineered for High Performance and Extreme Durability
In the modern industrial era, precision casting (specifically lost-wax investment casting) has become the backbone of critical infrastructure and high-tech sectors. From the aerospace turbines of North America to the heavy-duty hydraulic systems of European construction machinery, the demand for dimensionally accurate, metallurgically sound components is at an all-time high. Custom precision casting parts are no longer just commodities; they are engineered solutions that determine the safety, efficiency, and longevity of the final assembly.
The global precision casting market is currently experiencing a "Precision Pivot." As industries like renewable energy (wind turbine components) and Electric Vehicles (EV lightweight chassis parts) expand, traditional casting methods are being replaced by high-precision investment casting. European and American enterprises are increasingly seeking Custom Suppliers and Manufacturers who can offer more than just a casting; they need a partner capable of co-engineering parts to reduce weight while increasing structural integrity.
China, particularly the Shandong region, has evolved from a mass-production hub to a center of High-Tech Precision Manufacturing. At JUNLONG Machinery Co., Ltd. (founded in 2014), we leverage the local industrial ecosystem to provide efficiencies that are unmatched globally. This is not just about labor costs—it is about "Supply Chain Density." Within a 100km radius of our Weifang facility, we have access to high-purity raw materials, advanced CNC tooling shops, and world-class surface treatment specialists.
Specializing in Carbon Steel, Alloy Steel, and Stainless Steel (including 304/316) for diverse industrial needs.
Comprehensive physical and chemical analysis equipment to ensure every batch meets ASTM and ISO standards.
Equipped with internationally advanced automated production lines to stabilize quality and reduce human error.
Our custom precision casting parts are designed for specific operational environments:
The industry is moving toward "Green Foundry" practices and "Digital Twins." By using AI-driven simulation software, we can predict shrinkage and porosity before the first mold is even created. This reduces material waste and speeds up the prototyping phase, a critical requirement for global enterprises aiming for shorter "Time-to-Market."
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. We are a high-quality casting supplier integrating precision casting and deep processing.
With over 200 employees, including more than 30 engineering technicians, we serve global industry leaders in Europe and America, including Germany, the United States, Italy, and Canada.

We are a key supplier for high-tech industries including:
Expert Insights into Precision Casting Procurement
We specialize in carbon steel (e.g., A27), alloy steel, and various grades of stainless steel (304, 316, 410). We can also customize chemical compositions to meet specific mechanical properties required by your engineering team.
Generally, mold design and sample production take 3-4 weeks. Once samples are approved, mass production usually takes 4-6 weeks depending on the order volume and complexity of machining required.
Every batch undergoes spectral analysis for chemical composition, mechanical property testing (tensile/hardness), and non-destructive testing (NDT) like Magnetic Particle Inspection or X-Ray if required. We strictly follow IATF 16949 standards for automotive components.
Yes, we provide a full range of surface treatments including zinc plating, hot-dip galvanizing, powder coating, painting, and electrophoresis to meet various corrosion resistance requirements.
While our annual capacity is 20,000 tons, we are structured to support both high-volume OEM production and specialized low-volume, high-complexity casting needs for mid-to-high-end clients.
Integrate advanced management and technical resources with our world-class precision casting services. Our engineering team is ready to review your blueprints and provide a competitive manufacturing solution.
