The global Investment Casting Market is currently experiencing a profound paradigm shift. Valued at over USD 20 billion, the industry is transitioning from traditional "shape-making" to "performance-engineering." As industries such as aerospace, medical, and renewable energy demand components with near-zero porosity and extreme dimensional stability, the role of a precision supplier has evolved into a strategic R&D partner.
In North America and Europe, the focus has shifted toward high-mix, low-volume aerospace components. Conversely, for industrial machinery, automotive, and infrastructure, the global procurement focus is firmly on China’s precision casting hubs. This isn't just about cost—it's about the "Elastic Supply Chain" capability where a single factory can scale from prototype to 20,000 tons of annual output while maintaining TS16949 rigorous automotive standards.
China’s investment casting sector, particularly in regions like Shandong, has integrated the entire value chain. Unlike fragmented Western suppliers, Chinese "Mega-Factories" like JUNLONG Machinery integrate mold design, silica sol/water glass casting, heat treatment, and 5-axis CNC machining under one roof.
This integration provides an Information Gain for procurement officers: by reducing the number of sub-contractors, you eliminate 30-40% of the potential "Quality Drift" often found in multi-factory logistics.
We are seeing a surge in demand for specialized alloys. Carbon steel remains the backbone of construction machinery, but the rise of Nickel-Alloy Steel and High-Manganese Steel for railway and oilfield protectors highlights a trend toward "Extreme Environment Survivability."
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.
With over 200 employees, including more than 30 engineering technicians, we integrate Precision Casting and Deep Processing. Our focus materials include Carbon Steel, Alloy Steel, and Stainless Steel, serving global leaders in the automotive, rail, and petroleum industries.

Providing high-precision railway parts that meet fatigue resistance standards for high-speed rail and heavy freight logistics. Our components ensure safety and longevity in high-stress rail environments.
Custom lost wax casting for harvesters, tractors, and soil preparation equipment. Our parts are engineered to withstand abrasive soil conditions and high-torque mechanical loads.
Utilizing stainless steel and nickel alloys to produce connecting rods and spare parts that resist saltwater corrosion and thermal stress in marine propulsion systems.
A new frontier for precision casting. We supply structural components for PV solar trackers that require extreme weather resistance and 25-year structural integrity.
Specialized alloy steel cable protectors and clamps. Precision casting ensures that these safety-critical parts maintain their grip and structural form under thousands of meters of downhole pressure.
The "backbone" of modern infrastructure. We produce excavator buckets, load-bearing joints, and crane components designed for extreme duty cycles.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment. Our facilities include:
The company has obtained ISO 9001, TS 16949, and UL certifications. We employ a zero-defect quality management philosophy, ensuring that every batch of precision casting components meets or exceeds the mechanical property requirements of our global clients.
The precision casting industry is moving toward Sustainability (ESG). By reducing waste in the lost wax process and optimizing energy consumption in induction melting, modern factories are meeting the "Green Procurement" requirements of European and American OEMs.
Furthermore, "Digital Twin" technology is being applied to mold flow analysis. Before a single gram of metal is poured, AI-driven simulations predict potential shrinkage or porosity issues, reducing prototype lead times by up to 50%.
Silica Sol casting offers superior surface finish (Ra 3.2-6.3) and tighter dimensional tolerances, making it ideal for stainless steel and complex aerospace/medical parts. Water Glass is more cost-effective for larger, less complex carbon steel components.
Every heat is tested via spectrometer before pouring. We also perform non-destructive testing (NDT), including X-ray and Magnetic Particle Inspection (MPI) upon request, to ensure subsurface integrity.
Typically, mold manufacturing takes 3-4 weeks. With our in-house mold shop, we can fast-track urgent prototypes to 2 weeks, including initial sample inspection reports (ISIR).
Yes, we operate a full-process machining workshop with CNC lathes and vertical machining centers, allowing us to deliver "ready-to-assemble" components.
We recommend 316L Stainless Steel or specialized Duplex Stainless Steels, which provide excellent resistance to pitting and crevice corrosion in seawater.
We maintain ISO 9001 and TS 16949 standards and offer flexible shipping terms (FOB, CIF, DDP). Our location near major ports in Shandong facilitates rapid global logistics.
Our company will continue to strengthen research and development efforts for new products and technologies, integrate advanced management and technical resources, and strive to become a world-class precision casting supplier!
